For just as, in those animals 15 III, 5 | simple tale, so much noised abroad, as Herodotus the storyteller, 16 I, 23| practically nothing, but beside absolute insensibility it seems most 17 II, 3 | separated from the mother) it absorbs nourishment and performs 18 II, 4 | by itself, if one should accept this cause. The real cause 19 V, 3 | heat per se and cold per accidens (since the moisture goes 20 IV, 4 | the parent. Therefore this accident also often invades animals 21 IV, 3 | not in reference to his accidental qualities (as for instance 22 II, 4 | takes place which is usually accompanied by pleasure in women as 23 I, 2 | change, many other changes accompany it, as would be the case 24 II, 4 | stated that the discharge accompanying sexual pleasure in the female 25 I, 23| it is necessary for it to accomplish the function of that which 26 I, 4 | internally, are all quicker in accomplishing copulation. But those which 27 IV, 4 | has burst open of its own accord or the physicians have removed 28 V, 2 | the region of breathing.~Accuracy then in judging the differences 29 IV, 6 | conspicuous and those who are accustomed to work bear children easily 30 II, 6 | but were not sufficiently acquainted with the facts. It is with 31 I, 21| and concoction, as the egg acquires nutriment so long as it 32 III, 9 | scolex, after progressing and acquiring their full size, become 33 II, 6 | pre-existing potentially but being actualized later by the same causes 34 I, 2 | mother as being female, but addressing Heaven and the Sun and other 35 IV, 4 | takes away from the size and adds the excess so gained to 36 I, 13| in the ovipara, the ducts adhere to the back and the region 37 III, 2 | brittle; this is so nicely adjusted that it is still soft when 38 V, 2 | workmanship of Nature is admirable also in the seal, for though 39 II, 6 | for the sake of the end admits of division into two classes, ( 40 III, 11| with putrefaction and an admixture of rain-water. For as the 41 I, 18| this view (if we are to adopt it), to a certain extent 42 III, 1 | seminal residuum. Hence the Adrianic fowls lay most eggs, for 43 V, 3 | by the time their age is advancing. Human beings also go grey 44 III, 4 | liquefies and the liquid is aerated. This is effected in animals 45 II, 2 | and the former is hot air (aerh); hence semen is liquid 46 V, 2 | catch the movement from afar and pass it on to the sense-organ.~ 47 II, 6 | very strong before it can affect parts so far from the first 48 II, 8 | which unite against their affinities. Democritus says that the 49 I, 20| have in their nature an affinity to the primitive matter.~ 50 III, 10| theories only if what they affirm agrees with the observed 51 IV, 6 | are not pregnant they are afflicted with ailments whenever the 52 III, 1 | residual matter, nature cannot afford to spend much upon both. 53 I, 3 | is the description of the aforesaid parts of animals.~ 54 IV, 6 | the eyes grow and sprout afresh. And in general the production 55 V, 1 | it is found more in the aged, for this part also like 56 V, 5 | hair and all weak things ageing sooner. It is said, however, 57 II, 7 | cotyledons are gradually aggregated from many into a few the 58 IV, 4 | the embryo, whenever it aggregates more material at any point 59 I, 14| bloodless animals do not agree either with the sanguinea 60 III, 1 | foods the concocted is more agreeable. It has been sufficiently 61 III, 2 | kind of heat. For the earth aids in the concoction by its 62 IV, 6 | they are afflicted with ailments whenever the catamenia do 63 IV, 10| other principles. It is the aim, then, of Nature to measure 64 II, 4 | must overflow. Then Nature, aiming at the best end, uses it 65 III, 2 | and what is asserted by Alcmaeon of Crotona. For it is not 66 V, 8 | however, consider it not alien to the discussion of generation 67 I, 17| or a few. Secondly, the alleged fact that mutilations are 68 IV, 6 | takes up some of it and so alleviates the mother. In the other 69 I, 18| excessive in quantity, is an alleviation (just as in the case of 70 IV, 3 | resolved into the movement next allied to it—if less, into that 71 I, 20| dryness of their bodies; this allows but little matter to be 72 III, 6 | mounts and is mounted in alternate years. This is untrue, for 73 I, 19| itself. I mention these alternatives here because we have not 74 II, 7 | in those birds that are amative, as partridges and hens. 75 II, 2 | drying that it becomes like amber. But this does not happen, 76 III, 6 | the raven family is not amorous, for they are birds that 77 II, 6 | formed the flesh or its analogues, being solidified by cold, 78 I, 1 | virtue of a similarity and analogy. For there is a slight distinction 79 I, 2 | ability or faculty, and anatomically by certain parts; essentially 80 IV, 3 | the likeness of the nearer ancestor than the more remote, both 81 III, 11| when a naval armament cast anchor at Rhodes a number of clay 82 IV, 3 | individual existence than is his animalhood. In generation both the 83 III, 1 | seems to be what happens to annuals, as leguminous plants, corn, 84 V, 5 | fact that it is aided by anointing with a mixture of oil and 85 III, 11| former. Because their nature answers to that of plants, therefore 86 IV, 1 | colder or hotter, more "antique" or more "recent". Democritus 87 I, 16| cicadae, spiders, wasps, and ants. Others unite indeed and 88 IV, 4 | the bladder, and when the anus was cut open it quickly 89 V, 8 | arts, e.g. the hammer and anvil in the smith’s art, so does 90 I, 21| Hence some of those who are anxious to rear fine birds act thus; 91 | Anyhow 92 | anywhere 93 II, 4 | the great vessel and the aorta, divide higher up, and many 94 III, 10| with bees, to judge from appearances. For they must (1) either 95 V, 1 | existent. For life most of all appertains to wakefulness, on account 96 IV, 3 | whom comes more semen, this applying equally both to the body 97 II, 7 | As the embryo grows and approaches perfection the cotyledons 98 IV, 1 | original appearance and approximate closely to the female form. 99 I, 22| concerned, as, for instance, architecture is in the buildings it makes.~ 100 I, 17| are inherited, for they argue that since the parent is 101 I, 17| proofs from which it can be argued that the semen comes from 102 IV, 1 | Democritus and any one else who argues on the same lines. For then 103 III, 6 | mouth? But this opinion has arisen because the young of the 104 III, 11| water; thus when a naval armament cast anchor at Rhodes a 105 I, 15| another and enfolding their arms. This attitude is necessary, 106 IV, 3 | all, so as to increase and arrange their form symmetrically; 107 I, 7 | but also of this elaborate arrangement in uniting.~ 108 I, 1 | has united them together, arranging the discussion of these 109 IV, 6 | but after birth it quickly arrives at maturity and old age 110 I, 17| confused and not clearly articulated. That is pretty much the 111 II, 4 | means of the tools of the artist, or to put it more truly 112 IV, 2 | not solidify it; for the artistic or natural product we need 113 V, 4 | antithesis of hoar-frost; if the ascending vapour be frozen it becomes 114 III, 11| In others again, as the ascidians, nothing of the sort is 115 II, 1 | as is said in the verse ascribed to Orpheus, for there he 116 II, 8 | solstice, in order that the ass-foals may be born in a warm season, 117 IV, 1 | him to fall into error in assigning this cause of his; but if 118 IV, 1 | in quality in those who assimilate nourishment properly. In 119 III, 10| leaders. The bees, then, are assimilated to them their power of generation, 120 III, 11| But the form which fire assumes never appears to be peculiar 121 I, 18| first efficient cause. For assuredly it is not in the sense of 122 IV, 3 | multiform, as happens with athletes because they eat so much. 123 V, 2 | in wet weather or a damp atmosphere.... And the ears seemed 124 V, 7 | they stretch the warp by attaching to it what are called "laiai". 125 IV, 4 | catamenia has arrived pain has attacked them, till either the passage 126 V, 1 | kind of sight. Cataract attacks the blue-eyed more, but 127 IV, 5 | latter when the foetus has attained to some size, for then they 128 II, 6 | nature-philosolphers made an attempt to state which part comes 129 V, 1 | Becoming or development attends upon Being and is for the 130 IV, 4 | once.~If, then, we must attribute the cause to the semen of 131 I, 20| are capable of pleasure by attrition. And those who have been 132 V, 3 | winter and summer, spring and autumn of man are defined by his 133 II, 1 | we should not say that an axe or other instrument or organ 134 II, 6 | they have been as it were baked in an oven by the heat in 135 IV, 9 | suspended from the cord as in a balance, inclines towards the heavy 136 I, 21| the wood, or in which a ball comes into being from the 137 IV, 5 | mares both because of the barrenness of their nature and because 138 II, 8 | empty. For all theories not based on the special principles 139 V, 8 | particular cases.~Now we assume, basing our assumption upon what 140 II, 7 | union of the "rhini" and "batus". And the proverb about 141 III, 2 | where the two cotyledons of beans and of similar seeds are 142 IV, 3 | compare some one who is not beautiful to a "goat breathing fire", 143 III, 10| the third stage. And so beautifully is this arranged by Nature 144 | became 145 II, 7 | puberty; the same thing may befall others as their years advance, 146 IV, 2 | of body are more wont to beget females, and a liquid semen 147 I, 21| cock before the egg has begun to whiten and while it is 148 III, 7 | cock. And if the eggs be behindhand in growth, then, if the 149 I, 17| the evidence on which some believe that the semen comes from 150 III, 10| theory and from what are believed to be the facts about them; 151 III, 4 | eggs, as the fish called "belone", for its eggs are large 152 II, 3 | When such a principle has ben imparted to the secretion 153 I, 20| and all quadrupeds which bend their hind-legs outwards, 154 II, 3 | soulless or in every sense bereft of life (since both the 155 | beside 156 III, 8 | uterus of the carabi is also bifid. All these animals also 157 IV, 5 | foetus of the elephant is as big as a calf. But superfoetation 158 II, 1 | cross-division. Not all bipeds are viviparous (for birds 159 II, 3 | of an animal have every bit as much life as a plant), 160 II, 8 | and lioness or of lion and bitch will be different from both 161 IV, 8 | must become of necessity bitter and ill-flavoured. As the 162 V, 7 | result being what some call "bleating"" when the voice is uneven. 163 I, 19| neither from haemorrhoids nor bleeding at the nose nor anything 164 I, 19| some cases to issue in a bloody condition if one forces 165 V, 5 | A sign of this is that a blow to this spot is fatal to 166 IV, 2 | than when south winds are blowing. For in the latter case 167 V, 1 | sight. Cataract attacks the blue-eyed more, but what is called " 168 III, 2 | of the hen later than the blunt end; for the part attached 169 III, 11| into being on the side of boats when the frothy mud putrefies. 170 I, 20| from one semen comes one bodys—for example, one stalk of 171 III, 1 | something of the kind and boil them over a fire so as not 172 III, 1 | sides, as when a liquid boils; for the white is naturally 173 II, 7 | the fertile sinks to the bottom, for that which is well 174 V, 1 | condition, being as it were a boundary between living and not living, 175 I, 20| diarrhoea is caused in the bowels by the insufficient concoction 176 III, 11| nor in the fresher among brackish waters, but only exceptionally, 177 V, 3 | curly-haired, for their brains and the surrounding air 178 II, 4 | from these smaller vessels branch off to the uterus. These 179 I, 17| Chalcedon where the father had a brand on his arm and the letter 180 I, 20| have risen two fingers’ breadth that the catamenia generally 181 II, 8 | from the male (wherefore breeders put the horse to the mare 182 I, 18| reason they thin them before breeding from them, and say that 183 III, 5 | union of such fishes is brief, so that it is not observed 184 V, 1 | nor a weak sight can see bright things because the liquid 185 II, 1 | softness, stickiness and brittleness, and whatever other qualities 186 V, 8 | is much nutriment in the broad part of the bones, whereas 187 III, 2 | concoction by its heat, and the brooding hen does the same, for she 188 II, 2 | smaller and less visible the bubbles in it, the whiter and firmer 189 III, 11| All those which do not bud off or "spawn" are spontaneously 190 III, 11| slips, planted out, some by budding off alongside, as the class 191 III, 11| original, and from this buds off each of the creatures 192 II, 1 | does this, as the act of building builds the house. Plainly, 193 I, 22| architecture is in the buildings it makes.~From these considerations 194 II, 1 | as the act of building builds the house. Plainly, then, 195 III, 1 | bodies are more fluid and bulkier, whereas those of game-fowl 196 IV, 2 | in cooking; too much fire burns the meat, too little does 197 III, 9 | and after this the latter bursts and there comes forth as 198 IV, 3 | fire", or again to a "ram butting", and a certain physiognomist 199 II, 1 | should move B, and B move C; that, in fact, the case 200 III, 8 | nature.~In the sepias and calamaries or squids the eggs appear 201 II, 7 | blood-vessel as along a canal; and each embryo is enclosed 202 V, 8 | shed any teeth except the canines, e.g. lions. This mistake, 203 I, 16| such are fleas, flies, and cantharides. Others again are neither 204 IV, 4 | a vine which some call "capneos"; if this bear black grapes 205 III, 2 | animals a special sense of care for their young: in the 206 I, 2 | Nature; but we must observe carefully the way in which this semen 207 V, 8 | further, all the animals with carnivorous dentition suckle, but some 208 IV, 1 | secrete and discharge a semen carrying with it the principle of 209 I, 4 | mounting immediately after castration has caused conception in 210 III, 6 | taken more frequently; this casual observation has given rise 211 V, 2 | passage long; these also catch the movement from afar and 212 II, 8 | neighbouring country and among the Celts beyond Iberia, for this 213 II, 5 | to them they develop in a chain one after another, as the 214 I, 17| and there was a case at Chalcedon where the father had a brand 215 III, 11| themselves; when certain Chians carried some live oysters 216 I, 21| cock, the whole brood of chicks turn out like the second 217 II, 4 | nothing to the embryo. The chief argument for the opposite 218 IV, 6 | the ease or difficulty of child-birth. These circumstances then, 219 II, 4 | called membranes and others choria, the difference being one 220 I, 16| sanguinea; such are the locusts, cicadae, spiders, wasps, and ants. 221 III, 3 | cannot harden and dry its circumference, being colder than birds), 222 III, 5 | from those of birds in one circumstance. Birds and all oviparous 223 I, 18| they say, they ought not to claim that it comes from all parts 224 III, 11| straits of the sea where tides clash, they became no more numerous 225 I, 19| in this class the fact is clearest in women, for the discharge 226 III, 8 | form and spherical, the cleavage being obscure when it is 227 V, 3 | others the nature of the climate is the cause. A proof of 228 V, 3 | condition of sheep in cold climates is opposite to that of man; 229 I, 18| contraries. Fourthly, as in the "climax" of Epicharmus; thus from 230 I, 1 | and animals that live by clinging to something else, inasmuch 231 II, 7 | catamenia are secreted, are clogged and closed. For the region 232 I, 14| alongside the intestine, cloven on each side, in which the 233 IV, 6 | and also it is more often cloven-hoofed, striving as it were with 234 II, 2 | water. What Ctesias the Cnidian has asserted of the semen 235 II, 2 | in their composition that coagulate and thicken on boiling, 236 I, 20| material. In fact, as in the coagulation of milk, the milk being 237 V, 3 | plain in man; the hair gets coarser as time goes on, and some 238 IV, 8 | umbilical cord lies as a coat collapse as the nourishment 239 IV, 5 | the hypozoma; but with the cock-birds it is the other way, for 240 V, 3 | the surrounding air and so coiled up together. For what is 241 IV, 4 | end of the penis has not coincided with the end of the passage 242 III, 2 | umbilicus running the chorion collapses first, because it is here 243 II, 4 | semen. The discharge and collection of the catamenia also excite 244 IV, 8 | becomes useful.~The milk collects in the upper part of the 245 III, 10| small in the cells of the comb, whereas, whenever insects 246 IV, 1 | from each parent and the combination of the two becomes male 247 III, 11| others the more complicated combinations of these, so that what the 248 III, 10| mould the first part of the combs, but they generate by copulation 249 I, 18| also makes the body more comfortable), and so it may be also 250 V, 4 | superficial. And so the comic poets make a good metaphor 251 V, 7 | sometimes, having complete command over it, make the movement 252 III, 4 | by the heat of the juice commingled with them. The eggs then 253 IV, 4 | depart a little from Nature commonly live; not so those which 254 I, 21| female? Or does the semen communicate nothing to the material 255 II, 7 | movements from the pudenda are communicated to the chest, and the smells 256 III, 11| water, of others the more complicated combinations of these, so 257 II, 2 | phlegm.~Semen, then, is a compound of spirit (pneuma) and water, 258 I, 16| observations are not yet comprehensive enough to enable us to make 259 II, 2 | air is forced together and compressed, as..., by the cold, the 260 II, 4 | force from the breath or compulsion of any other cause, as some 261 II, 7 | towards the uterus, the concavity towards the embryo. Between 262 I, 19| is that often the female conceives without the sensation of 263 I, 2 | material of it. The most conclusive proof of this is drawn from 264 IV, 1 | the two sexes is only a concomitant result; not this but something 265 IV, 3 | is no difficulty in both concurring, for Socrates is an individual 266 V, 3 | not only hardens but also condenses, heat makes a substance 267 V, 8 | teeth quicker, heat being conducive to growth.~They are shed, 268 II, 4 | part. Hence it acts like cone-shaped vessels which, when they 269 IV, 2 | other male. Observed facts confirm what we have said. For more 270 I, 19| secretion as the semen is, and confirmation of this view may be drawn 271 I, 21| This a priori argument is confirmed by the facts. For it is 272 I, 12| hard so that it will not conform to the size of anything 273 II, 6 | then, are made in the first conformation of the parts from the seminal 274 II, 4 | embryo may be moulded in conformity with those of the mother. 275 IV, 1 | something of the sort, we must confront them in the same way as 276 III, 2 | white on the contrary is not congealed by frost but rather liquefies ( 277 V, 3 | and petrified through the congealing effect of the cold. In the 278 III, 2 | that of the yolk; the yolk congeals in frosts but liquefies 279 I, 17| to their parents, not in congenital but also in acquired characteristics; 280 I, 5 | of the female, but they conjugate standing upright because 281 II, 6 | touch the bones they are not connate with them. They are formed, 282 I, 2 | case of each, and we must connect our account with what has 283 II, 4 | development is completed by connection with the uterus, and therefore 284 I, 16| other; such are gnats, "conopes", and many similar kinds. 285 I, 18| secretion. For the exhaustion consequent on the loss of even a very 286 III, 10| rate the whole class would consist of leaders. The bees, then, 287 II, 4 | this is a blood-vessel, consisting of one or more vessels in 288 II, 7 | to the uterus. The cord consists of blood-vessels in a sheath, 289 I, 20| pungently-flavoured foods cause them to be conspicuously increased. And as to the 290 I, 22| but further material must constantly be added that it may increase 291 IV, 6 | and elsewhere; for work consumes the residual matter, but 292 IV, 7 | her size reduced, but she continued thus for three or four years 293 II, 1 | touched something though not continuing to touch it. In a way it 294 I, 13| of the back, which gives continuity and stability. Now in those 295 II, 6 | for even if they had grown continuously they would still have been 296 V, 3 | curliness will then be a contraction owing to deficiency of moisture 297 V, 7 | are the reasons of these contrarieties, that neither are all young 298 II, 7 | in the parts and regions contributory to copulation. Some such 299 IV, 3 | contributed by the mother is not controlled by them, at last there remains 300 II, 4 | the uterus chance to be conveniently placed and hot on account 301 I, 18| body of the male either. Conversely, if it does not come from 302 IV, 5 | secretion of the female is converted to the first formed embryo 303 II, 7 | found the cotyledons). Their convexity is turned towards the uterus, 304 II, 4 | from the nourishment they convey, nor is the female nature 305 II, 3 | from the male the spiritus conveying the principle of soul. Of 306 IV, 2 | meat, too little does not cook it, and in either case the 307 IV, 7 | the womb as to meats half cooked in roasting, and it is not 308 IV, 2 | Otherwise it will be as in cooking; too much fire burns the 309 II, 6 | little moisture and heat, cool as the moisture evaporates 310 IV, 5 | generative discharge is copious, and because the body is 311 III, 1 | annuals, as leguminous plants, corn, and the like. For they 312 III, 5 | the facts. They say quite correctly that no animal which copulates 313 IV, 2 | they also need a certain correspondence with one another to produce 314 I, 18| actually die of it. For corrupt humours collect here as 315 IV, 8 | is blood concocted (not corrupted; Empedocles either mistook 316 I, 18| contrary, are always due to corruption or decay and to a departure 317 II, 7 | into a few the body of the cotyledon becomes like an eruption 318 III, 11| element of fire, for this is counted in as the fourth of the 319 II, 1 | for horses, cattle, and countless others are viviparous), 320 V, 3 | Aethiopians and men in hot countries are curly-haired, for their 321 V, 6 | account the fact that it is covered by the mouth but looking 322 V, 5 | protected by hats or other coverings goes grey sooner (for the 323 III, 1 | nature, as is shown by the cowardice of the bird, whereas a generative 324 III, 1 | hot and moist. That it is cowardly is plain, for it is pursued 325 V, 5 | It is said, however, that cranes become darker as they grow 326 I, 18| resemblance. If again something creates this composition later, 327 I, 18| Empedocles accounts for the creation of animals; in the time 328 I, 18| of it, but only from the creative part—from the workman, so 329 IV, 10| animal of which we have any credible experience except the elephant, 330 II, 1 | viviparous (for lizards, crocodiles, and many others lay eggs). 331 III, 1 | fruit, wither away after the crop when nutriment is not reserved 332 II, 1 | These classes admit of much cross-division. Not all bipeds are viviparous ( 333 II, 8 | and the offspring of both crosses are barren, according to 334 II, 8 | are produced also from the crossing of horse and ass when the 335 III, 2 | asserted by Alcmaeon of Crotona. For it is not the white 336 IV, 4 | ended below, so that they crouch sitting to void it, and 337 IV, 6 | which lay many eggs, as crows and rooks, jays, sparrows, 338 IV, 3 | and what crushes is itself crushed again. Sometimes it is altogether 339 IV, 3 | way pushed again and what crushes is itself crushed again. 340 II, 1 | such are those of fishes, crustaceans, and cephalopods, for their 341 II, 6 | invertebrates is testaceous or crustaceous, in the vertebrates it is 342 V, 1 | asleep they both laugh and cry. For animals have sensations 343 II, 2 | it is made of water. What Ctesias the Cnidian has asserted 344 III, 1 | year four, and again three cubs, then the next number down 345 II, 4 | parts attract the semen like cupping-glasses, aided by the force of the 346 II, 7 | copulation. Some such cases are curable, others incurable, but the 347 IV, 4 | not separated if it has to curdle a large quantity of milk, 348 IV, 4 | much the greater is the curdled mass. Now it is no use to 349 II, 3 | that of the fig-juice which curdles milk, for this too changes 350 I, 21| form; so the medical art cures the patient.~This a priori 351 II, 1 | automatic machines shown as curiosities. For the parts of such machines 352 V, 3 | men in hot countries are curly-haired, for their brains and the 353 IV, 4 | contrary to the general and customary rule.~Man belongs to all 354 I, 12| are visible, they have a cuticular covering known as the scrotum. 355 IV, 3 | it acts; thus that which cuts is blunted by that which 356 V, 8 | long time, the last of them cutting the gum at about twenty 357 I, 18| plant or animal.~Again, the cuttings from a plant bear seed; 358 I, 18| we must reflect that the daily nutriment by which animals 359 V, 2 | happens in wet weather or a damp atmosphere.... And the ears 360 V, 6 | of the white-haired and dark-haired are white and dark in each 361 V, 5 | through its weakness and is darkened by sun and wind, while the 362 V, 5 | however, that cranes become darker as they grow old. The reason 363 IV, 4 | a certain motion, if it dash against anything two systems 364 I, 23| forms the embryo in several days. And after emitting this 365 II, 1 | equivocal sense (as the eye of a dead man is still called an " 366 V, 4 | liquid nutriment in the hair decays because it is not concocted, 367 III, 5 | being.~What helps in the deception is also the fact that the 368 V, 3 | evergreens while others are deciduous, and birds which hibernate 369 I, 18| says agrees with it when he declares that there is a sort of 370 I, 19| develop. So, too, in the decline of life the generative power 371 V, 4 | of heat. For as the body declines in vigour we tend to cold 372 III, 1 | are taken out to act as decoys, whether they have ever 373 V, 7 | the same animals will be deep-and loud-voiced, and the same 374 V, 1 | unfathomable water is dark or deep-blue on account of its depth). 375 V, 7 | the high-voiced becoming deeper-voiced than they were, and the 376 V, 3 | surface of the skin, not deeply rooted in it, and so is 377 IV, 1 | its proper form, but is defeated in this respect, then must 378 IV, 4 | upon its leg. Changes and deficiencies are found also in the internal 379 IV, 1 | But the animal becomes definitely female or male by the time 380 I, 7 | cooled if it were further delayed by testes. (This happens 381 II, 8 | intelligibly. For they offer their demonstration in the case of all these 382 V, 3 | and old age, as the word denotes, is earthy because the heat 383 V, 3 | the pores, but if it is denser they are thin because of 384 II, 8 | hollows in each fit into the densities of the other, and in such 385 V, 8 | animals with carnivorous dentition suckle, but some of them 386 III, 10| tendance of these creatures deny this, it remains that the 387 IV, 3 | cases Nature has in a way departed from the type. The first 388 I, 2 | changes in other things depending on it. This is plain in 389 II, 1 | eggs they lay, for they deposit a quantity of sticky material 390 III, 8 | the cephalopoda grow after deposition like those of fishes.~The 391 II, 6 | Cooling, again, is mere deprivation of heat. Nature makes use 392 II, 3 | animals neither is fire nor derives its origin from fire.~Let 393 II, 4 | heat and the uterus to have descended. But generally speaking 394 I, 11| as in birds, for the egg descends and the young is hatched 395 IV, 4 | intercourse, it is better not to desert the short road to go a long 396 II, 4 | from that moment does this deserve to be called its principle 397 II, 4 | locomotive. So Nature has first designed the two blood-vessels from 398 IV, 1 | the faculty produces the desired results in a lower degree 399 I, 23| in plants, their nature desiring that they shall become one; 400 I, 18| less semen and are less desirous of intercourse. Like this 401 I, 20| indicates that the parts destined to receive each of these 402 II, 6 | being in proportion to their detrition. And so Nature has contrived 403 III, 10| certain extent, but are devoid of the extraordinary features 404 II, 6 | right angles, or that the diagonal of a square is incommensurable 405 II, 6 | body as in the anatomical diagrams which are represented on 406 I, 18| of this, others actually die of it. For corrupt humours 407 III, 1 | two eggs in a day, have died after this. For both the 408 II, 6 | so also the quantitative differentia comes into being, pre-existing 409 II, 3 | potentially even those parts which differentiate the female from the male, 410 I, 20| question are on the point of differentiating they are distended by the 411 I, 11| Thirdly, parturition would be difficult because of the length of 412 I, 18| repeated the pleasure is diminished in the persons concerned). 413 III, 5 | comes down the ducts and diminishes in quantity at the same 414 II, 6 | motion is not connected directly with it, as that of the 415 I, 2 | only the generative part is disabled, yet pretty well the whole 416 II, 8 | sterility. The ass has all the disadvantages already mentioned, and if 417 IV, 10| say, the full moon and her disappearance and the halves of the times 418 IV, 4 | rather evaporates and at last disappears and is dried up. Now since 419 IV, 6 | gestation is attended with discomfort. Their way of life is partly 420 I, 18| comes into being. We must discover then, in which of the two 421 II, 3 | from another in honour and dishonour, so differs also the nature 422 V, 7 | the rest the air is better dispensed. As their age advances this 423 V, 1 | because the movement is not dispersed in space but comes straight 424 IV, 5 | birds the hens are less disposed that way than the cocks, 425 I, 18| the mutual proportion or disproportion of that comes from the woman 426 III, 5 | cartilaginous, for they do not dispute the sexes in these. And 427 IV, 1 | between male and female.~It is disputed, however, whether the embryo 428 I, 11| such animals the uterus is dissimilar to that of both the vivipara 429 II, 6 | which is why it is also dissolved by fire. But all the particles 430 II, 3 | This material of the semen dissolves and evaporates because it 431 I, 20| differentiating they are distended by the spiritus; this is 432 II, 4 | the heart appears first distinctly marked off in all the sanguinea, 433 I, 2 | any rate, when that which distinguishes male and female suffers 434 III, 6 | for observation in some districts, but hyenas have under the 435 V, 1 | neither too little so as to be disturbed and hinder the movement 436 IV, 2 | with one another, but if divorced and remarried to others 437 II, 7 | of a dog with some wild dog-like animal. A similar thing 438 II, 4 | fox and dog, partridge and domestic fowl, but as time goes on 439 III, 6 | family; this is plain with domesticated jackdaws. Birds of the pigeon 440 I, 2 | the semen; for there is no doubt that it is out of this that 441 V, 1 | perception is not like a dream. So infants presumably have 442 V, 1 | and do many things without dreaming. For there are some who 443 III, 2 | eggs, for if the bird be drenched with water or suddenly chilled 444 V, 6 | to the water which they drink, for hot waters make the 445 III, 1 | only bird of prey which drinks, and its moisture, both 446 V, 3 | advances as a stream, not in drops. For this reason the Scythians 447 V, 8 | has been drawn off from a dropsical patient on account of the 448 II, 6 | heaviness through sleepiness or drunkenness or anything else of the 449 IV, 4 | other female]. When such duplication occurs the one is always 450 V, 1 | they see less well in the dusk, for the nocturnal light 451 II, 8 | ginnus", that is to say, a dwarf mule; for "ginni" are produced 452 II, 8 | pig. The origin of human dwarfs is similar, for these also 453 II, 4 | outside at later period to dwell in it, not only may the 454 III, 11| the season advances they dwindle and at last disappear altogether; 455 IV, 7 | three or four years until dysentery came on, endangering her 456 V, 1 | is a difficulty about the earliest period of development, whether 457 III, 11| if ever they were really "earth-born" as some say, they came 458 IV, 6 | upon which depends the ease or difficulty of child-birth. 459 I, 18| is, for then it will be easier to inquire into its operations 460 V, 2 | and project far like the eaves of a house, as in some quadrupeds, 461 II, 5 | neither male nor female, as eels and a kind of mullets found 462 III, 4 | liquid is aerated. This is effected in animals by the nature 463 I, 20| the male stands for the effective and active, and the female, 464 V, 4 | diseases produce the same effects as old age.~Men go grey 465 V, 4 | inadequate the part loses its efficiency, and destruction or disease 466 I, 20| not lay eggs) have this effluxion is the dryness of their 467 II, 6 | while some of them, as egg-shells, are soluble in liquids. 468 IV, 4 | than one at a time, as in Egypt. And they are commoner in 469 IV, 4 | between, for even those of eight months do live though less 470 IV, 8 | On the tenth day of the eighth month the milk comes into 471 II, 8 | admit the impregnation, but ejects the semen with her urine, 472 I, 7 | the ducts but also of this elaborate arrangement in uniting.~ 473 IV, 5 | birth even if a long time elapses between the two impregnations, 474 II, 6 | soft, the sinews solid and elastic, the bones solid and brittle. 475 III, 11| in as the fourth of the elementary bodies. But the form which 476 I, 18| the case of the woman in Elis who had intercourse with 477 III, 1 | that walk, and all may be embraced in the same general statement; 478 III, 11| honourable in kind depends on the embracing of the psychical principle; 479 III, 1 | as in birds is found an embryonic formation without impregnation, 480 IV, 4 | monstrosities arose because two emissions of seminal fluid met together, 481 II, 1 | the movement of the tools employed, this movement containing 482 I, 16| comprehensive enough to enable us to make a distinction 483 II, 1 | the same as the power that enables an animal or plant to generate 484 III, 2 | one to the membrane which encloses the yolk, the other to the 485 I, 12| too hard to be adapted for enclosing them or for being soft like 486 IV, 5 | intercourse. In females then it encourages copulation to have the uterus 487 III, 3 | the flesh in like manner encroaches upon and grows round it.~ 488 IV, 7 | until dysentery came on, endangering her life, and she produced 489 I, 19| since that which Nature endows with a smaller portion of 490 I, 15| against one another and enfolding their arms. This attitude 491 II, 1 | realization in actuality as engaged in mathematics than when 492 V, 8 | animals those young which enjoy hotter milk grow their teeth 493 I, 4 | for their testes are much enlarged at the time of copulation, 494 III, 5 | number of eggs in these is enormous.
