501 II, 8 | jackasses to the females at the equinox, as they do with horses, 502 II, 1 | will be a part except in an equivocal sense (as the eye of a dead 503 II, 1 | or soul in it; it is only equivocally that they will be called 504 III, 5 | his milt upon them. Some erroneously assert that all fish are 505 IV, 1 | natural for him to fall into error in assigning this cause 506 II, 7 | cotyledon becomes like an eruption or inflammation. So long 507 IV, 7 | does occur and has entirely escaped observation. We must suppose 508 IV, 3 | Now that which is acted on escapes and is not mastered by the 509 II, 1 | since the male and female essences are the first principles 510 I, 2 | anatomically by certain parts; essentially the male is that which is 511 III, 11| exceptionally, but it is in estuaries and at the mouths of rivers 512 II, 6 | always happens or what exists eternally; it is an eternal truth 513 I, 19| the greater part has been evacuated, the remainder is formed 514 II, 6 | large, but in course of evaporation and concoction it becomes 515 IV, 5 | after the first, for such an event has been observed before 516 V, 3 | unctuous plants are more evergreen. (However we must elsewhere 517 V, 3 | among plants also some are evergreens while others are deciduous, 518 I, 18| the opposite. Now it is evident that it cannot be of the 519 II, 2 | difficulty. If it is water, water evidently does not thicken through 520 IV, 1 | abundance is an evidence of the exact opposite of what some suppose, 521 I, 20| semen comes one bodys—for example, one stalk of wheat from 522 II, 7 | studied with the aid of the examples drawn in the Anatomy and 523 IV, 4 | between these limits that they exceed or fall short of one another 524 IV, 5 | in males) and mares have exceedingly little. And in all the vivipara 525 I, 20| emission of semen and far exceeds it. Moreover, different 526 I, 23| insensibility it seems most excellent; for it would seem a treasure 527 III, 11| brackish waters, but only exceptionally, but it is in estuaries 528 I, 1 | in the sanguinea with few exceptions the creature, when its growth 529 IV, 1 | have one or other testis excised, not speaking truth but 530 II, 4 | collection of the catamenia also excite heat in this part. Hence 531 III, 1 | small when they are in this excited condition, and the secreting 532 I, 1 | from decaying earth and excrements. To speak generally, if 533 II, 4 | than man’s; so the blood is excreted through very fine vessels 534 II, 4 | force the secretions or excretions are discharged in sleep 535 V, 4 | between the two extremes is exempt from both states. The cause 536 IV, 6 | travail is painful. But work exercises them so that they can hold 537 II, 4 | bring the same to pass and exert the same formative power 538 II, 4 | than they do without the exertion of such a force. Their reason 539 V, 3 | moisture evaporating and exhaling in them, and therefore thick 540 III, 1 | birds the plants become exhausted, and this condition is an 541 I, 19| and healthy blood is an exhausting thing; for this reason also 542 IV, 3 | from the forces of all such existences that the efficient movements 543 III, 3 | so it would prevent their exit. And while the egg of the 544 III, 7 | copulation, as Nature prefers to expend the milt in helping to perfect 545 I, 20| because the pleasure she experiences is sometimes similar to 546 II, 4 | conceive, however, without experiencing the pleasure usual in such 547 V, 2 | less well during a yawn or expiration than during inspiration, 548 IV, 4 | bear most fruit.~We have explained then why some animals naturally 549 IV, 3 | it aims at what is better expressed by saying that what is called " 550 II, 8 | Democritus, of whom the former expresses himself obscurely, the latter 551 I, 4 | spermatic secretion, so that its expulsion is slower than in fishes. 552 II, 6 | heart the blood-vessels extend throughout the body as in 553 I, 18| to suppose that the last extract of the nutriment which goes 554 IV, 4 | deficiency in such parts, e.g. an extremity or one of the other members, 555 II, 6 | the legs is not. Now the eyelid is such a part. But since 556 IV, 3 | physiognomist reduced all faces to those of two or three 557 I, 20| is found in those who are fair-skinned and of a feminine type generally, 558 V, 1 | come into being without falling under the heads just mentioned, 559 III, 2 | in intelligence we find familiarity and love shown also towards 560 IV, 1 | whole character seems to be fanciful. If, however, the facts 561 I, 4 | attached to them, as women fasten stones to the loom when 562 V, 3 | they are found in sixty fathoms and even more). The spines 563 V, 3 | feathers and scales in the feathered and scaly kinds. For their 564 II, 4 | breath, but this is a common feature of all cases when it is 565 III, 10| devoid of the extraordinary features which characterize bees; 566 V, 3 | should expect the brain to feel the effect of it first, 567 IV, 2 | advanced age, alike as concerns fertility or infertility, and as concerns 568 I, 21| them, and those eggs are fertilized which it reaches, but not 569 I, 20| sometimes divided into more or fewer parts, and sometimes not 570 V, 1 | suppose that the blue are fiery, as Empedocles says, while 571 II, 1 | and the cephalopods. The fifth and coldest class does not 572 III, 5 | as olive and oleaster, fig and caprifig. They think 573 I, 1 | do, as in the case of the fig-tree and caprifig.~The same holds 574 III, 10| idle as having no weapon to fight for the food and because 575 II, 4 | blood-vessels, and this filling the channels of the finest 576 V, 3 | thick-skinned animals are fine-haired for the cause previously 577 II, 4 | filling the channels of the finest vessels must overflow. Then 578 IV, 4 | larger than the others, as a finger or hand or foot or any of 579 I, 20| when they have risen two fingers’ breadth that the catamenia 580 II, 1 | potentially such as the finished product. Now the semen is 581 II, 2 | bubbles in it, the whiter and firmer does the mass appear. The 582 IV, 1 | state. And as one part of first-rate importance changes, the 583 III, 5 | overlooked the fact that fish-eggs differ from those of birds 584 IV, 10| these that the moon’s orbit fits in with that of the sun [ 585 II, 4 | brings into one mass and fixes the similar material, and 586 I, 13| of the female, and this fixing must take place at either 587 I, 14| the other prone. For the flaps attached to the sides of 588 V, 6 | are both hotter and better flavoured for the same reason; the 589 I, 11| in all the vivipara it is fleshy, whereas when the uterus 590 III, 1 | birds which are not given to flight nor rapine but which produce 591 II, 2 | bears it up and makes it float, being the cause of its 592 II, 2 | water). This too is why it floats on the surface of the water, 593 II, 8 | urine, wherefore men follow flogging her after intercourse. Again 594 I, 18| during a short time in the flower of their youth the loss 595 III, 10| spontaneously generated in the flowers or whether some animal generates 596 III, 1 | grows through this matter flowing to it through the uterus. 597 II, 6 | rid of its coldness and fluidity; this applies to all animals 598 II, 3 | included in the semen and the foam-like, and the natural principle 599 I, 4 | steadier, preserving the folding back of the passages in 600 III, 6 | also are those who make a foolish statement about the trochus 601 II, 6 | to this argument, which forbids us to seek the cause, there 602 II, 2 | but because the air is forced together and compressed, 603 | formerly 604 II, 7 | the cord run backwards and forwards between embryo and uterus 605 IV, 1 | the semen, which is the foundation of the embryo, is the ultimate 606 II, 7 | they occur with dogs and foxes and wolves; the Indian dogs 607 I, 19| which the foetus can be framed by the power coming from 608 IV, 1 | the flesh lies as round a framework. It is not reasonable that 609 III, 10| young, should remain within, freed from the labour of procuring 610 II, 2 | oil is thickened without freezing in cold weather and frosts; 611 IV, 4 | so-called "metachoera" are most frequent, and the condition of these 612 III, 11| produced in lakes nor in the fresher among brackish waters, but 613 I, 18| because there is a strong friction (wherefore if this intercourse 614 III, 3 | externally perfected (the frog-fishes) and those internally, and 615 III, 2 | contrary is not congealed by frost but rather liquefies (the 616 V, 6 | causes whiteness, as also in froth. As, then, skins which are 617 V, 4 | the ascending vapour be frozen it becomes hoar-frost, if 618 III, 5 | bears fruit but the other is fruitless, as olive and oleaster, 619 IV, 4 | occurs the one is always functional but not the other, because 620 I, 2 | organs are needed for all functioning, and since the bodily parts 621 I, 3 | as in man or towards the fundament as in swine. They have been 622 I, 15| arm of the male into the funnel of the female, by which 623 I, 18| Further, if the parts of the future animal are separated in 624 V, 7 | part which moves the air gains more strength in each animal, 625 IV, 4 | also which naturally have a gall-bladder are found without one; others 626 V, 7 | testes are themselves a ganglion of many principles, but 627 V, 1 | eye itself; as on a clean garment even small stains are visible, 628 I, 22| considerations we may also gather how it is that the male 629 I, 21| if we take the highest genera under which they each fall, 630 I, 18| recur at an interval of many generations, as in the case of the woman 631 II, 8 | Democritus says that the genital passages of mules are spoilt 632 IV, 1 | germs or seeds; for the germ, they say, comes from the 633 II, 4 | continuous and excessive, prevent girls from growing. This secretion 634 I, 16| with each other; such are gnats, "conopes", and many similar 635 I, 19| the two sexes reach their goal together, yet often no conception 636 V, 1 | grey-eyed, and some are yellow (goat-eyed), as the majority of goats 637 II, 2 | from this they named the goddess who presides over union.)~ 638 III, 1 | impregnation in chickens and goslings. Also the female partridges 639 IV, 3 | this, then into that of her grandmother; and similarly also with 640 IV, 1 | if it could be taken for granted that all blood is equally 641 IV, 4 | capneos"; if this bear black grapes they do not judge it a monstrosity 642 III, 10| not yet been sufficiently grasped; if ever they are, then 643 V, 5 | hair does not whiten as grass does by withering, is shown 644 V, 1 | the whole kind is blue or grey-eyed, and some are yellow (goat-eyed), 645 V, 7 | if it is expelled as by a groan, the note is deeper.~The 646 IV, 3 | responsible for the following groups of facts. (1) Some children 647 III, 10| from their own kind. The grubs of the kings are produced 648 I, 12| egg or foetus, which needs guarding, shelter, and maturation 649 II, 3 | is clear that we must be guided by this in speaking of the 650 V, 8 | last of them cutting the gum at about twenty years of 651 V, 7 | heat or cold also of their habitat contributes to make some 652 III, 1 | are thick owing to their habits, so that for all these reasons 653 IV, 4 | where a phenomenon occurs habitually, as in fruits; for instance, 654 II, 4 | the result is a sort of haemorrhage. The period is not accurately 655 I, 19| women suffer neither from haemorrhoids nor bleeding at the nose 656 IV, 5 | wherefore among men also the hairy are given to sexual intercourse 657 IV, 7 | of its hardness, as with half-cooked meat, for this half-dressing 658 IV, 7 | half-cooked meat, for this half-dressing of meat is also a sort of 659 IV, 10| her disappearance and the halves of the times between these, 660 V, 8 | uses in the arts, e.g. the hammer and anvil in the smith’s 661 V, 7 | string and make it taut by hanging some weight on to it, as 662 IV, 3 | changes not into anything haphazard but into its opposite, therefore 663 III, 3 | soft-shelled (for they cannot harden and dry its circumference, 664 IV, 7 | become so hard that they can hardly be cut through even by iron. 665 IV, 5 | than the smooth. In the hare it often happens that some 666 I, 18| waste-product it would be always harmful; as it is, it is not so.]~ 667 I, 4 | desire being too violent and hasty. It is for this that the 668 | hath 669 V, 5 | fact that hair protected by hats or other coverings goes 670 II, 7 | hens. Among birds of prey hawks of different form are thought 671 I, 18| too much nutrition, for he-goats when fat are less inclined 672 III, 2 | vivipara; the latter are born head-first, the part where is the first 673 IV, 9 | birth of all animals is head-foremost, because the parts above 674 V, 7 | particularly sinewy, even their hearts, and therefore that part 675 I, 2 | being female, but addressing Heaven and the Sun and other like 676 II, 5 | female animal needs the help of the male, for in these 677 III, 5 | animal comes into being.~What helps in the deception is also 678 III, 1 | secretion corresponding in hen-birds to catamenia, and the semen 679 III, 6 | hyena, and Herodorus the Heracleot says that the trochus, has 680 | hereafter 681 III, 6 | say that the hyena, and Herodorus the Heracleot says that 682 II, 5 | class of fishes makes us hesitate. No male of the so-called 683 I, 18| manner of generation? For the heteroeneous parts are composed of the 684 V, 1 | other, then the result is heteroglaucia.~The cause of some animals 685 V, 3 | baldness, although both hibernating animals recover their feathers 686 I, 13| but they have their testes hidden under the abdominal cavity.~ 687 V, 7 | loud-voiced, and the same will be high-and not loud-voiced; but this 688 V, 7 | note is better than the high-pitched ones, the better lying in 689 V, 7 | the air being slow and its highness on its being quick, there 690 I, 20| quadrupeds which bend their hind-legs outwards, for all these 691 I, 19| from the distinctions drawn hitherto whether it is the matter 692 V, 5 | fatal to them, wherefore Homer also has said: "where the 693 I, 18| parts are composed of the homogneous, so that to come from the 694 II, 3 | differs from another in honour and dishonour, so differs 695 IV, 4 | a goat being born with a horn upon its leg. Changes and 696 III, 3 | have said in the "smooth hound".~In these respects and 697 V, 2 | are long, as the Laconian hounds, are keen-scented, for the 698 II, 6 | anything useful. Now in a household the best part of the food 699 II, 6 | For Nature, like a good householder, is not in the habit of 700 IV, 3 | quantity of unconcocted humour or wind being diverted into 701 I, 18| actually die of it. For corrupt humours collect here as in the urine, 702 IV, 7 | had intercourse with her husband and supposed she had conceived, 703 II, 4 | to both parents, as the hybrid between fox and dog, partridge 704 III, 6 | observation in some districts, but hyenas have under the tail a line 705 II, 8 | and among the Celts beyond Iberia, for this country also is 706 III, 6 | say that the raven and the ibis unite at the mouth, and 707 V, 1 | necessity (for the fundamental idea of the animal is of such 708 III, 10| that the drones should be idle as having no weapon to fight 709 III, 11| elements, for that which is ignited appears to be either air 710 II | Book II~ 711 III | Book III~ 712 IV, 8 | of necessity bitter and ill-flavoured. As the embryo is perfecting, 713 I, 18| make this clearer by an illustration, take a written name; if 714 III, 10| investigated with the aid of the illustrations to the Enquiries.~ 715 II, 6 | always happens so", and imagine that this is a first principle 716 III, 11| that from which it came, by imparting motion to which the principle 717 IV, 4 | physicians have removed the impediment; some such cases have ended 718 III, 9 | their nature, because of its imperfection, oviposits as it were before 719 III, 2 | Nature seems to wish to implant in animals a special sense 720 I, 18| body in copulation, they imply that it is a kind of waste-product. 721 I, 18| arguments and the view involves impossibilities. First, then, the resemblance 722 III, 6 | female, and that the trochus impregnates itself but the hyena mounts 723 IV, 5 | elapses between the two impregnations, if their kind is spermatic, 724 V, 6 | things by the vaporous air imprisoned in them. Hence also in all 725 I, 20| with the semen, as this impure nutriment in plants is nutritious 726 I, 18| not found to carry off the impurity, and though some recover 727 V, 4 | the part; if the heat is inadequate the part loses its efficiency, 728 I, 7 | intertwine because of their inaptitude to cast themselves alongside 729 V, 3 | human beings to whom it is incident. For leaves are shed by 730 V, 8 | which the lancet made the incision.~We have thus spoken of 731 IV, 9 | the cord as in a balance, inclines towards the heavy end, and 732 I, 3 | for the membranes which include their so-called eggs are 733 I, 20| all discharges of blood, including that of the catamenia, for 734 III, 11| generate it is from the incoming nourishment that the heat 735 II, 6 | diagonal of a square is incommensurable with the side, and nevertheless 736 III, 2 | moment of giving birth to the incompletely developed animal; in others 737 IV, 5 | those women also who are incontinent in regard to such intercourse 738 III, 2 | the egg by the mother’s incubating and aiding the concoction, 739 II, 7 | cases are curable, others incurable, but the subjects especially 740 III, 1 | as not coming into being independently but as mere relics from 741 II, 7 | and foxes and wolves; the Indian dogs also spring from the 742 I, 19| The following signs also indicate that this discharge in females 743 I, 20| catamenia in the female; this indicates that the parts destined 744 I, 4 | past that they are almost indiscernible, but during the season they 745 III, 5 | speculating on a small induction, they think the same must 746 II, 7 | intercourse, and those who indulge too much in this are seen 747 V, 7 | voice, and of all similar inequality, is that the part or organ 748 I, 1 | this would have gone on to infinity. But Nature flies from the 749 II, 7 | becomes like an eruption or inflammation. So long as the embryo is 750 V, 7 | roughness, flexibility and inflexibility. We must inquire then into 751 IV, 6 | developed, when the injury is inflicted, so that the eyes grow and 752 I, 18| that is lost but also other influences come away mingled with it, 753 I, 19| coming from the male and inherent in the semen, and in the 754 I, 17| fact that mutilations are inherited, for they argue that since 755 II, 1 | has in itself the movement initiated by the other.)~It is possible, 756 II, 7 | this state is caused by injuries in the parts and regions 757 II, 4 | are excessive, they are injurious, either causing illness 758 III, 2 | sharp end. Under this is the inner membrane which separates 759 I, 18| the cause of this must be inquired into later, for this problem 760 II, 1 | into being, but we now are inquiring not out of what the parts 761 I, 23| nothing, but beside absolute insensibility it seems most excellent; 762 II, 4 | analogous to the uterus being inserted into the male.~It has been 763 I, 15| uterine passage. But the insertion, in the case of the poulps, 764 II, 6 | and hence the bones are insoluble by fire like pottery, for 765 I, 11| uterus must be gathered from inspection of the drawings of dissections 766 V, 2 | or expiration than during inspiration, because the starting-point 767 II, 7 | but many close together insteadall these have in the uterus 768 I, 20| caused in the bowels by the insufficient concoction of the blood, 769 IV, 4 | other, because it is always insufficiently supplied with nourishment 770 III, 2 | the greatest portion in intelligence we find familiarity and 771 II, 8 | his principles from the intelligible. How do the "hollows" and " 772 II, 8 | obscurely, the latter more intelligibly. For they offer their demonstration 773 II, 8 | again, the argument is intended to apply to both male and 774 I, 17| reduced to four. First, the intensity of the pleasure of coition; 775 I, 19| kind occurs the flow is interfered with because the discharge 776 III, 1 | have eggs almost without intermission, though very small ones. 777 I, 7 | and others not. Serpents intertwine because of their inaptitude 778 I, 7 | suppleness of their bodies, intertwining. Wherefore also they seem 779 II, 8 | horse to the mare again at intervals). Indeed, both the mare 780 II, 6 | formed completely, for in the intervening time they collapse. The 781 V, 4 | white the whiteness does not invade the skin. The reason is 782 IV, 4 | this accident also often invades animals of such a nature. 783 II, 2 | spirit, for it is also an invariable rule that it is white, and 784 II, 6 | reason the covering of the invertebrates is testaceous or crustaceous, 785 V, 8 | cause too generally without investigating the facts in all cases. 786 V, 1 | earlier than that in the investigations concerning soul—if this 787 II, 2 | sense that each bubble is invisible, which is what happens when 788 II, 5 | in question was seen to involve the male quality. Certainly 789 IV, 4 | the period of gestation is irregular; whereas the period is fixed 790 IV, 3 | therefore their limbs develop irregularly, sometimes indeed almost 791 II, 1 | exists in the product itself, issuing from another nature which 792 IV | Book IV~ 793 II, 8 | stallion and she-ass or jackass and mare, why in the last 794 II, 8 | cause they do not put the jackasses to the females at the equinox, 795 III, 6 | plain with domesticated jackdaws. Birds of the pigeon kind 796 IV, 6 | eggs, as crows and rooks, jays, sparrows, swallows, and 797 V, 4 | make a good metaphor in jest when they call grey hairs " 798 IV, 3 | defect of growth. Hence often jesters compare some one who is 799 II, 4 | and shelter. The vessels join on to the uterus like the 800 V, 7 | young being weaker in the joints and sinews; moreover, in 801 IV, 3 | if one should mix many juices in one liquid and then take 802 IV, 1 | happen from probabilities and jumping at the conclusion that it 803 V, 2 | the Laconian hounds, are keen-scented, for the sense-organ being 804 IV, 4 | nor could they succeed in keeping it open.~We have now spoken 805 V, 5 | decay and the protection keeps off the winds), and the 806 III, 1 | tread nor lay much. The kestrel is the most fertile; for 807 IV, 4 | two spleens or with one kidney; there is no case again 808 V, 1 | working upon the animal kingdom as a whole, nor yet characteristic 809 IV, 3 | is that this is closely knit up with the individual characteristics; " 810 II, 1 | being in the same way as the knitting of a net. That the former 811 V, 7 | there is a difficulty in knowing whether it is that which 812 IV, 6 | nations where the women live a laborious life gestation is not equally 813 V, 2 | nostrils are long, as the Laconian hounds, are keen-scented, 814 V, 7 | attaching to it what are called "laiai". For in this way are the 815 III, 1 | This is what we find in lake birds, for they are of a 816 III, 11| nature are not produced in lakes nor in the fresher among 817 I, 6 | copulation, as viviparous land-animals do, but they have it all 818 III, 11| plants were, so to say, land-oysters, oysters water-plants.~For 819 V, 1 | through, and that is why lanterns cannot give light if they 820 III, 1 | residual matter is secreted largely in the heavy birds not given 821 IV, 4 | all cases; for it is the largeness and smallness of the body 822 III, 1 | And such birds are of a lascivious and fertile nature, so that 823 II, 6 | old age and death. If life lasted for a thousand or ten thousand 824 II, 6 | and the end; thirdly and lastly, the organic parts serving 825 II, 2 | to air. And if oxide of lead is mixed with water or even 826 III, 10| case the facts about their leadership would be unreasonable), 827 III, 2 | where is the first principle leading, but the egg is discharged 828 I, 15| to void the excrement and leads to the part like a uterus, 829 V, 3 | bald" and "the fall of the leaf" and "moulting". The cause 830 I, 19| produce less semen than lean ones, as observed before. 831 III, 1 | whereas those of game-fowl are leaner and drier, since a passionate 832 II, 6 | as the teacher before the learner, and the other later, as 833 II, 6 | pipes are later than he who learns to play upon them, for it 834 III, 7 | treads the hen again after leaving off treading for a time, 835 III, 1 | so that the so-called "lecithus" or yolk in the eggs of 836 IV, 4 | born with a horn upon its leg. Changes and deficiencies 837 III, 6 | they have not had the same legend told of them. But the raven 838 V, 6 | kind is vari-coloured, as leopards and peacocks, and some fish, 839 IV, 1 | respectively; so at least Leophanes asserted. And some say that 840 V, 4 | for in what is called leprosy the hairs become white; 841 III, 11| oysters over from Pyrrha in Lesbos and placed them in narrow 842 I, 17| brand on his arm and the letter was marked on the child, 843 I, 18| if from these, from the letters and their composition. So 844 III, 1 | the partridge, and the Libyan ostrich lay many eggs, while 845 IV, 1 | Empedocles has made a rather light-hearted assumption in thinking that 846 II, 2 | being the cause of its lightness. So too oil is thickened 847 IV, 4 | of all this, but a number limited by the appropriate size 848 V, 3 | state as the scrapings from linen, for these also are not 849 II, 2 | and water, it ought not to liquefy entirely and turn to water.~ 850 I, 23| union.~And animals seem literally to be like divided plants, 851 II, 6 | would grow as long as they lived, for these set the limit 852 I, 1 | animals which change their locality, some by swimming, others 853 I, 2 | the part used for sight or locomotion—which part is also plain 854 IV, 10| that the development of the long-lived animals should take a longer 855 IV, 10| yet the larger are not all longer-lived.
