For the former remain paired some part of a day, while 1002 II, 6 | boiling that they may be more palatable or for any other purpose. 1003 V, 1 | the eye of all sheep is pale, of others again the whole 1004 I, 19| other animals. Wherefore her pallor and the absence of prominent 1005 I, 18| comes from, i.e. after, the Panathenaea; nor yet as contraries come 1006 III, 10| is a thing which may be paralleled in other animals, but that 1007 II, 1 | and non-existence, and can partake in the better and the worse. 1008 I, 18| the discharge of the semen participates in both characteristics 1009 I, 6 | when it is received by and passes through this latter part, 1010 IV, 5 | intercourse cease from their passion for it when they have borne 1011 III, 1 | leaner and drier, since a passionate spirit is found rather in 1012 I, 4 | them so small when this is past that they are almost indiscernible, 1013 V, 6 | vari-coloured, as leopards and peacocks, and some fish, e.g. the 1014 III, 11| sometimes smaller; in others as pectens, mussels, and the so-called 1015 I, 1 | and with reference to the peculiarities of each kind, explaining 1016 I, 3 | others outside, either pendent as in man or towards the 1017 II, 7 | smells from the chest are perceived through the respiration.~ 1018 IV, 8 | ill-flavoured. As the embryo is perfecting, the residual matter left 1019 V, 7 | for if the breath of the performer is hotter, that is to say 1020 II, 3 | absorbs nourishment and performs the function of the nutritive 1021 IV, 4 | animals; there was a cow in Perinthus which passed fine matter, 1022 II, 5 | the existent, and that of perishing is back again from the existent 1023 V, 1 | colour which is to be theirs permanently. But in the case of other 1024 II, 7 | see if the smells thereof permeate from below upwards to the 1025 IV, 1 | several times.~Some again, persuaded of the truth of a view resembling 1026 V, 6 | course of development is perverted, for what is small is easily 1027 V, 3 | formed; they are hard and petrified through the congealing effect 1028 II, 6 | is in worse condition or physically defective, in like manner 1029 IV, 4 | of its own accord or the physicians have removed the impediment; 1030 IV, 3 | butting", and a certain physiognomist reduced all faces to those 1031 V, 5 | it is dark, if they are piebald in consequence of a mixture 1032 III, 11| in some testacea, as in pinnae, whelks, and purple-fish; 1033 III, 2 | cord, and projects like a pipe from them while they are 1034 V, 7 | opposite. This is clear also in pipe-playing, for if the breath of the 1035 V, 1 | eyes, height and depth of pitch in the voice, and differences 1036 V, 1 | further; in fact, men in pits or wells sometimes see the 1037 III, 2 | shell. These details are plainer in the larger creatures; 1038 III, 11| from seed, some from slips, planted out, some by budding off 1039 III, 11| nature of liquid is more plastic than that of earth and yet 1040 II, 8 | might appear to be more plausible than those already given; 1041 III, 11| to be formed still more plentifully in proportion if some are 1042 II, 2 | is a compound of spirit (pneuma) and water, and the former 1043 V, 4 | superficial. And so the comic poets make a good metaphor in 1044 III, 8 | alone has its front and back pointing in the same direction. For 1045 II, 6 | they breathe. Moreover, all polydactylous quadrupeds, as dog, lion, 1046 V, 3 | concerned is weak and in poor condition. Thus if we reckon 1047 I, 18| all, as by the willow and poplar. This condition is due to 1048 V, 3 | moisture and besides is very porous.~The cause of the hairs 1049 IV, 4 | such cases seem to be more portentous, because they are contrary 1050 II, 6 | Other animals are born in possession of teeth or their analogue ( 1051 II, 2 | not discriminated all the possibilities. It is not only the liquids 1052 I, 1 | this is only a reasonable postulate to make, for it is plainly 1053 V, 7 | accordance with the distinction postulated, the result will be that 1054 V, 7 | small in size, are great in potency; this, indeed, is what is 1055 I, 22| with his timber and the potter with his clay, and generally 1056 III, 8 | shape of the uterus in the poulp is round in form and spherical, 1057 II, 2 | entangled in it by the act of pounding them together, and oil itself 1058 I, 18| mixing, as wine when water is poured into it. For in that case 1059 V, 7 | these ages are weak and powerless for movement. And bulls 1060 II, 6 | differentia comes into being, pre-existing potentially but being actualized 1061 I, 20| coming together of which precedes the emission. This is plain 1062 II, 6 | perfected, and the lung and the preceding parts are differentiated 1063 III, 2 | different in nature. The precise details of the relation 1064 II, 2 | only substances having a predominance of earth in their composition 1065 II, 3 | impossible for them all to preexist is clear from this consideration. 1066 I, 18| is formed from something preexisting which is only put into shape. 1067 III, 7 | for copulation, as Nature prefers to expend the milt in helping 1068 IV, 6 | troubled (for if they are not pregnant they are afflicted with 1069 IV, 1 | its opposite. After these premisses it will perhaps be now clearer 1070 IV, 2 | certain ratio. Now if the hot preponderates too much it dries up the 1071 I, 4 | spermatic secretion steadier, preserving the folding back of the 1072 II, 2 | they named the goddess who presides over union.)~This then is 1073 V, 3 | them, for as the heat is pressed out the moisture evaporates, 1074 V, 1 | like a dream. So infants presumably have sense-perception and 1075 I, 2 | in copulation that differ primarily in their forms, we must 1076 I, 18| up the question what the primary nature of what is called 1077 I, 20| nature an affinity to the primitive matter.~ 1078 V, 3 | kind of hair occurs. The principal cause then of thickness 1079 IV, 1 | vaticinating what will happen from probabilities and jumping at the conclusion 1080 IV, 3 | female and resembling most probably its mother, but, if the 1081 IV, 10| and of the end of these processes. Just as we see the sea 1082 I, 18| proves sometimes incapable of procreation because the seminal element 1083 III, 10| freed from the labour of procuring necessaries, and also that 1084 II, 1 | this is that, in all the productions of Nature or of art, what 1085 I, 8 | them imperfect, for it is profitable that it should be so. And 1086 III, 9 | nature of a scolex, after progressing and acquiring their full 1087 III, 2 | resembles an umbilical cord, and projects like a pipe from them while 1088 I, 14| one supine and the other prone. For the flaps attached 1089 I, 17| this question first.~The proofs from which it can be argued 1090 II, 2 | in it (for shininess is a property of air, not of earth or 1091 IV, 4 | male need to stand in some proportionate relation to one another ( 1092 II, 2 | explanation of the problem proposed, and it is plain too that 1093 V, 5 | statement is the fact that hair protected by hats or other coverings 1094 III, 2 | so rather for the sake of protecting them than of incubation.~ 1095 I, 12| well suited to keep the protective part separate.~[The position 1096 V, 5 | this would be, if it should prove true, that their feathers 1097 II, 7 | rhini" and "batus". And the proverb about Libya, that "Libya 1098 II, 4 | necessary for the female to provide a body and a material mass, 1099 V, 3 | with the exception of the pubic hair; for women also grow 1100 II, 4 | either causing illness or pulling down the patient; hence 1101 V, 2 | causes in some animals the pulsation of the heart and in others 1102 I, 20| discharges; for instance some pungently-flavoured foods cause them to be conspicuously 1103 II, 1 | the so-called chrysalis or pupa is equivalent to an egg); 1104 II, 8 | parents, e.g. male and female puppies from male and female dog. 1105 II, 7 | later). And the seminal purgations are from the region of the 1106 II, 4 | health, for they act as a purification of the secretions which 1107 I, 20| but needs working up to purify it. Thus the catamenia cause 1108 V, 2 | and smells depends on the purity of the sense-organ and of 1109 III, 1 | cowardly is plain, for it is pursued by all the birds and lays 1110 II, 6 | the lower, for the roots push out from the seed before 1111 IV, 3 | pushes is itself in a way pushed again and what crushes is 1112 IV, 3 | motion in return; e.g. what pushes is itself in a way pushed 1113 I, 15| entwine together at the mouth, pushing against one another and 1114 III, 11| putrefaction and the thing putrefied is only a residue of that 1115 III, 11| boats when the frothy mud putrefies. In many places where previously 1116 I, 19| character of the female—putting all these considerations 1117 III, 11| some live oysters over from Pyrrha in Lesbos and placed them 1118 I, 8 | the eggs of birds and the quadrupedal ovipara are perfect when 1119 III, 11| matter is present in large quantities, and consequently the testaceous 1120 III, 11| proportion as liquid has more quickening power than solid, water 1121 V, 7 | cause of the slowness or quickness. For some say that what 1122 I, 18| thus from slander comes railing and from this fighting, 1123 III, 11| putrefaction and an admixture of rain-water. For as the sweet is separated 1124 III, 10| drones are produced but in rainy reasons a large brood of 1125 III, 3 | the young, the passages ran to the uterus. This happens 1126 III, 1 | not given to flight nor rapine but which produce many young, 1127 IV, 2 | exist in virtue of a certain ratio. Now if the hot preponderates 1128 II, 3 | of the sensitive and the rational soul. For all three kinds 1129 II, 4 | when this is so there is a readier way for the semen of the 1130 I, 21| those who are anxious to rear fine birds act thus; they 1131 V, 3 | from the brain, we should reasonably expect baldness to come 1132 III, 6 | are deceived by a false reasoning, because the copulation 1133 IV, 1 | any part you please.~To recapitulate, we say that the semen, 1134 IV, 1 | quantity, wherefore the recipient parts of this secretion 1135 V, 3 | poor condition. Thus if we reckon up these points, that the 1136 V, 4 | hairs. But when men have recovered health and strength again 1137 V, 5 | of age, they go grey. The reddish hairs go grey sooner than 1138 V, 5 | grey sooner than the black, redness also being a sort of weakness 1139 IV, 1 | and the other is unable to reduce the residual secretion to 1140 V, 8 | neglecting the final cause, reduces to necessity all the operations 1141 V, 1 | animal’s being, but we must refer the causes to the material 1142 I, 18| of nutriment. But we must reflect that the daily nutriment 1143 IV, 1 | as the cause without any reflection, yet, as the form of the 1144 I, 18| likely, for it is not hard to refute the above arguments and 1145 I, 18| put, whether it is to be regarded as matter, and therefore 1146 I, 3 | sanguinea are not all alike as regards testes and uterus. Taking 1147 V, 7 | deep one, since it easily regulates the breath, becoming itself 1148 IV, 4 | entering into the uterus reinforced the earlier so that the 1149 IV, 3 | resembling none of their relations, yet do at any rate resemble 1150 V, 7 | sometimes absolutely, sometimes relatively to one another. Whether 1151 V, 7 | the voice is relaxed. This relaxation is just as if one should 1152 V, 8 | blunted, so that a fresh relay is needed for the work, 1153 III, 1 | independently but as mere relics from a previous impregnation. 1154 I, 18| and weakness rather than relief, for the reason given. Moreover, 1155 I, 19| has been evacuated, the remainder is formed into a foetus. 1156 IV, 4 | before now the os uteri has remained closed, so that when the 1157 IV, 2 | another, but if divorced and remarried to others do generate; and 1158 V, 3 | sea-urchins which are used as a remedy in stranguries. For these, 1159 V, 4 | being cold and dry. We must remember that the nutriment coming 1160 I, 18| are always morbid, but the removal of the secretion is useful; 1161 III, 11| it is in the one case art removes the useless material, in 1162 V, 1 | Moreover it is possible to render another account of the cause 1163 I, 18| this intercourse is often repeated the pleasure is diminished 1164 II, 2 | and Herodotus does not report the truth when he says that 1165 III, 11| one may say practically no representatives in the sea and such places, 1166 II, 1 | Something then of the sort we require exists in the embryo itself, 1167 III, 1 | crop when nutriment is not reserved for themselves, and this 1168 I, 18| the passage of the solid residua. Moreover, waste-products 1169 V, 4 | hairs instead of them after restoration to health. The reason is 1170 II, 4 | altogether is as much as what is retained within those animals which 1171 I, 14| crustacea copulate like the retromingent quadrupeds, fitting their 1172 IV, 4 | of the excess of material returning to that place whence it 1173 V, 1 | of seeing keenly or the reverse, but also the nature of 1174 IV, 10| birth and death.~As for the revolutions of the sun and moon, they 1175 II, 7 | spring from the union of the "rhini" and "batus". And the proverb 1176 II, 7 | sea, but the so-called "rhinobates" especially is thought to 1177 III, 11| armament cast anchor at Rhodes a number of clay vessels 1178 IV, 6 | of its body, being like a rich soil—which has sufficient 1179 IV, 6 | along with the young, as ring-doves, turtle-doves, and pigeons. 1180 I, 1 | themselves, yet contribute to the ripening of the fruits of those which 1181 I, 20| for it is when they have risen two fingers’ breadth that 1182 III, 2 | heats from the sediment rising (for this is the cause of 1183 III, 2 | If exposed to heat and roasted it does not become hard, 1184 IV, 7 | to meats half cooked in roasting, and it is not due to heat, 1185 IV, 6 | many eggs, as crows and rooks, jays, sparrows, swallows, 1186 V, 3 | of the skin, not deeply rooted in it, and so is not long 1187 V, 7 | the trachea or when it is roughened by any affection, for then 1188 I, 19| those of men, and women are rounder and smoother because the 1189 IV, 4 | they may be seen lying in a row in animals that produce 1190 IV, 4 | or possessing them in a rudimentary condition, or too numerous 1191 IV, 4 | have ended in death if the rupture has been made too violently 1192 III, 1 | their bodies chance to be in rut they emit semen at the mere 1193 I, 12| it is expedient for the safety and growth of the foetus 1194 II, 7 | to see if they colour the saliva. If these results do not 1195 III, 7 | that this has not yet been satisfactorily observed. But as it is both 1196 IV, 3 | face appears like that of a satyr owing to a quantity of unconcocted 1197 IV, 3 | also the disease known as satyrism, in which the face appears 1198 V, 3 | is soft but that of the Sauromatic sheep is hard. The reason 1199 II, 6 | there were not some means of saving them; even as it is they 1200 III, 11| therefore the oysters are savoury at these periods. A proof 1201 V, 3 | curliness, quantity and scantiness, and in addition to these 1202 I, 19| to some extent, but are scanty and do not last during all 1203 I, 17| mark in the form of the scar in the same place, and there 1204 I, 17| when the parents have had scars, the children have been 1205 IV, 3 | instance if the parent is a scholar or the neighbour of some 1206 II, 8 | into questions of natural science in this fashion any more 1207 I, 21| creatures give birth to scoleces.~What occurs in birds and 1208 V, 3 | much the same state as the scrapings from linen, for these also 1209 I, 12| cuticular covering known as the scrotum. If the nature of the skin 1210 II, 8 | cannot bear cold, as in Scythia and the neighbouring country 1211 V, 3 | also what happens in the sea-urchins which are used as a remedy 1212 V, 2 | is admirable also in the seal, for though a viviparous 1213 I, 22| able to do anything by any secondary means, but the movements 1214 III, 1 | excited condition, and the secreting activity takes place quickly 1215 I, 6 | passage resembles the last section of the reflected part of 1216 | seemed 1217 II, 4 | seeds of plants are always segregated to the places where they 1218 I, 18| single coition and a single segregation of the semen scattered throughout 1219 III, 3 | given,’ but the so-called "selache" or cartilaginous fishes 1220 I, 19| a single mixture of two semens, or whether no semen is 1221 III, 2 | the inner membrane which separates the white and the yolk from 1222 III, 8 | like those of fishes.~The sepia while developing is attached 1223 II, 6 | lastly, the organic parts serving these for certain uses. 1224 V, 2 | moves the breath, for while setting the breath in motion it 1225 V, 7 | is uneven. After this it settles into the deep or high voice 1226 IV, 10| and all bodies of water settling and changing according to 1227 IV, 6 | This is plain also with seven-months children, for since they 1228 IV, 8 | milk is useless before the seventh month and only then becomes 1229 I, 18| semen, but, as it were, a severance from a new plant or animal.~ 1230 V, 1 | even that it may not cast a shade the liquid behind it by 1231 V, 2 | sight do with those who shadow the eyes with the hand.~ 1232 III, 9 | but we must not judge by shapes nor yet by softness and 1233 I, 13| the liquid excretion also shares the same passage. This is 1234 III, 2 | not perfectly round but sharper at one end, is that the 1235 II, 7 | consists of blood-vessels in a sheath, more numerous in the larger 1236 II, 1 | by the protection of the shell-like covering. Hence fishes, 1237 III, 3 | to them since the mother shelters them, and the shell is a 1238 IV, 2 | colder as it wanes.~The shepherds also say that it not only 1239 II, 2 | mass and makes the white shine through, as in foam and 1240 II, 2 | has much air in it (for shininess is a property of air, not 1241 V, 6 | water in them, and the air shining through causes whiteness, 1242 V, 1 | by "black", what is not shone through, and that is why 1243 IV, 10| to them, though living a shorter time than man, yet carry 1244 V, 3 | and softness, length and shortness, straightness and curliness, 1245 III, 8 | themselves, which is why the side-flaps of the females are larger 1246 I, 11| their eggs are high up and sideways, but the living young are 1247 II, 6 | as the moving power, but simultaneous with the whole embryo if 1248 II, 7 | surface, but the fertile sinks to the bottom, for that 1249 IV, 4 | below, so that they crouch sitting to void it, and if the testes 1250 III, 1 | birth she produces five or six, then in the next year four, 1251 V, 3 | depth (for they are found in sixty fathoms and even more). 1252 IV, 4 | generally speaking, their sizes correspond to this difference.) 1253 II, 6 | for painters, too, first sketch in the animal with lines 1254 II, 4 | animals. Round these is a skin-like integument, because the 1255 V, 5 | first hairs grow on the skull of horses, and a wound is 1256 II, 6 | residue of the best for the slaves, and the worst is given 1257 V, 1 | and not living, and the sleeper being neither altogether 1258 II, 6 | little heaviness through sleepiness or drunkenness or anything 1259 IV, 8 | moulding the embryo but only on slightly increasing its growth, it 1260 III, 11| emit masses of a liquid slime as if originated by something 1261 III, 11| produced from seed, some from slips, planted out, some by budding 1262 II, 7 | the mouth and by colours smeared upon the eyes to see if 1263 V, 8 | hammer and anvil in the smith’s art, so does breath in 1264 III, 11| appears to be either air or smoke or earth. Such a kind of 1265 V, 3 | arising in them. If it be smoke-like, it is hot and dry and so 1266 V, 8 | be blunted but are only smoothed in time by wearing down), 1267 I, 19| and women are rounder and smoother because the secretion which 1268 IV, 4 | is one and indivisible.~A snake has also been observed with 1269 II, 1 | lizards and tortoises and most snakes; for the eggs of all these 1270 V, 7 | and in like manner some soft-voiced ones are deep-voiced, and 1271 II, 6 | and therefore they are softened by fire but none of them 1272 V, 3 | animals. The cold hardens and solidifies them by drying them, for 1273 III, 11| hardening round them and solidifying in the same manner as bones 1274 II, 8 | horses, but about the summer solstice, in order that the ass-foals 1275 V, 7 | the nobler nature, and in songs the deep note is better 1276 II, 6 | become white, black, and all sorts of colours according to 1277 II, 3 | the unfertilized embryo as soulless or in every sense bereft 1278 V, 7 | meant by "voice" and by "sound" generally, has been stated 1279 V, 2 | judging the differences of sounds and smells depends on the 1280 III, 2 | for just as wines turn sour in the heats from the sediment 1281 II, 6 | the colours.~Because the source of the sensations is in 1282 IV, 2 | place during northern or southerly winds, but even if the animals 1283 II, 4 | country in which they are sown. For it is the soil that 1284 IV, 5 | bear many their uterus is spacious, because they are spermatic 1285 II, 6 | Nature has some residue to spare.~The bones, then, are made 1286 II, 5 | been seen, but females, and specimens full of roe, have been seen. 1287 III, 5 | and not obvious, and so, speculating on a small induction, they 1288 I, 6 | their copulation should be speedy. Such is the nature of fish 1289 III, 4 | the whole development were spent in this growth; even as 1290 III, 8 | poulp is round in form and spherical, the cleavage being obscure 1291 I, 13| back and the region of the spine. For they must not wander 1292 I, 21| laid her eggs, the male spinkles the milt over them, and 1293 V, 2 | quadrupeds, with the internal spiral passage long; these also 1294 II, 7 | between embryo and uterus and split up into smaller vessels 1295 I, 15| to the eye but afterwards splits up into many; each of these 1296 III, 2 | applies to the eggs that are spoiling because of the yolk. It 1297 IV, 4 | curdling milk, which we spoke of before, is no longer 1298 II, 8 | such deficiency occurs sporadically, but the whole of the mule 1299 I, 18| Love", says he, "many heads sprang up without necks," and later 1300 II, 7 | thin and cold is quickly spread out on the surface, but 1301 III, 5 | outside are preserved by the sprinkling of the milt over them, even 1302 IV, 6 | so that the eyes grow and sprout afresh. And in general the 1303 II, 6 | hoofs, horns, beaks, the spurs of cocks, and any other 1304 II, 6 | or that the diagonal of a square is incommensurable with 1305 III, 5 | manifest that semen can be squeezed out of males of both classes 1306 I, 8 | the shell is made by heat squeezing out the moisture for the 1307 III, 8 | sepias and calamaries or squids the eggs appear to be two, 1308 I, 13| which gives continuity and stability. Now in those which have 1309 II, 5 | kind of mullets found in stagnant waters. But whenever the 1310 V, 1 | clean garment even small stains are visible, so also in 1311 I, 20| one bodys—for example, one stalk of wheat from one grain, 1312 V, 2 | were of one and the same stamp, so that a man can say what 1313 I, 5 | female, but they conjugate standing upright because of their 1314 I, 20| differ. If, then, the male stands for the effective and active, 1315 II, 5 | the point from whence she started. For the process of becoming 1316 II, 1 | perhaps some one of the statements made cannot be made without 1317 I, 18| another if we say that a statue is made from bronze and 1318 II, 5 | changing place, but that they stay where they are and the movement 1319 I, 4 | the spermatic secretion steadier, preserving the folding 1320 II, 1 | that hardness and softness, stickiness and brittleness, and whatever 1321 I, 12| for them, if chilled and stiffened, to be drawn up and discharge 1322 III, 10| and while the drones are stingless all the bees have a sting. 1323 III, 1 | having bulky bodies and their stomachs being hot and very active 1324 I, 4 | to them, as women fasten stones to the loom when weaving; 1325 V, 3 | harder, more earthy, and stony, if the region in which 1326 V, 1 | in the eye, being strong, stops that from outside, and in 1327 II, 4 | results that this time is stormier than the middle of the month. 1328 III, 6 | 6~A similar story is told also of the generation 1329 III, 5 | abroad, as Herodotus the storyteller, as if fish were conceived 1330 V, 3 | softness, length and shortness, straightness and curliness, quantity 1331 I, 5 | Wherefore also the legs are strained in intercourse, both the 1332 III, 11| and placed them in narrow straits of the sea where tides clash, 1333 V, 3 | are used as a remedy in stranguries. For these, too, though 1334 V, 7 | state, like a sinewy string stretched tight.
