  Bloodless animals are all inferior in point of size to blooded animals; but there are found in the sea some few bloodless creatures of larger size, as in the case of certain molluscs. And of these bloodless genera, those are the largest that dwell in [25] milder climates, and those that inhabit the sea are larger than those living on dry land or in fresh water.

  All creatures that are capable of motion move with four or more points of motion; the blooded animals with four only: as, for instance, man with two hands and two feet, birds with two wings and two feet, quadrupeds and fishes severally [30] with four feet and four fins. Creatures that have two fins, or that have none at all like serpents, move all the same with four points of motion; for they have four joints, or two plus their fins. Bloodless many-footed animals, whether furnished with wings or feet, move with more than four points of motion; as, for instance, the dayfly moves with four feet and four wings—for this creature is exceptional not only in [490b1] regard to the duration of its existence, whence it receives its name, but also because though a quadruped it has wings also.

  All animals move alike, four-footed and many-footed; they all move cross-corner-wise. And animals in general have two feet in advance; the crab alone has [5] four.

  6 · Very extensive genera of animals, into which other subdivisions fall, are the following: one, of birds; one, of fishes; and another, of cetaceans. Now all these creatures are blooded.

  There is another genus of the hard-shell kind, which is called the shell-fish; [10] another of the soft-shell kind, not designated by a single term, such as the crayfish and the various kinds of crabs and lobsters; and another of molluscs, as the two kinds of calamary and the cuttle-fish; that of insects is different. All these are bloodless, and such of them as have feet have a large number of them; and of the [15] insects some have wings as well as feet.

  Of the other animals the genera are not extensive. For in them one species does not comprehend many species; but in one case, as man, the species is simple, admitting of no differentiation, while other cases admit of differentiation, but the species lack particular designations.

  So, for instance, creatures that are quadrupedal and unprovided with wings [20] are blooded without exception, but some of them are viviparous, and some oviparous. Such as are viviparous are hair-coated, and such as are oviparous have a horny tessellation—the tessellation holds the place of scales.

  An animal that is blooded and terrestrial, but is naturally unprovided with feet, belongs to the serpent genus; and animals of this genus possess tessellation. Serpents in general are oviparous; the adder alone is viviparous; for not all [25] viviparous animals are hair-coated, and some fishes also are viviparous.

  All animals, however, that are hair-coated are viviparous. For one must regard as a kind of hair such prickly hairs as hedgehogs and porcupines carry; for these spines perform the office of hair, and not of feet as is the case with similar parts in [30] sea-urchins.

  In the genus that combines all viviparous quadrupeds are many species, but under no common appellation. They are only named as it were one by one, as man is—e.g. the lion, the stag, the horse, the dog, and so on; though there is actually8 a single genus in the case of the so-called bushy-tailed animals, such as the horse, the [491a1] ass, the mule, the jennet, and the animals that are called mules in Syria,—from their resembling mules, though they are not strictly of the same species, for they mate with and breed from one another.

  For all these reasons, we must take animals species by species, and discuss [5] their peculiarities severally.

  These preceding statements, then, have been put forward thus in a general way, as a kind of foretaste of the number of subjects and of the properties that we have to consider in order that we may first get a clear notion of their actual differences and common properties. By and by we shall discuss these matters with [10] greater accuracy.

  After this we shall pass on to the discussion of causes. For to do this when the investigation of the details is complete is the natural method; for from them the subjects and the premisses of our proof become clear.

  In the first place we must look to the constituent parts of animals. For it is [15] relative to these parts, first and foremost, that animals in their entirety differ from one another: either in the fact that some have this or that, while they have not that or this; or by peculiarities of position or of arrangement; or by the differences that have been previously mentioned, depending upon form, on excess, on analogy, or on contrariety of qualities.

  To begin with, we must take into consideration the parts of man. For, just as [20] any group tests coinage against that with which it is most familiar, so must we do in other matters. And, of course, man is the animal with which we are the most familiar.

  Now the parts are obvious enough to perception. However, with the view of observing due order and sequence and of combining reason with perception, we [25] shall proceed to enumerate the parts: firstly, the organic, and afterwards the uniform.

  7 · The chief parts into which the body as a whole is divided, are the head, the neck, the thorax, two arms and two legs.

  [30] Of the parts of which the head is composed the hair-covered portion is called the skull. The front portion of it is termed the sinciput, developed after birth—for it is the last of all the bones in the body to acquire solidity,—the hinder part is termed the occiput, and the part intervening between the sinciput and the occiput is the crown. The brain lies underneath the sinciput; the occiput is hollow. The skull [491b1] consists entirely of thin bone, rounded in shape, and contained within a wrapper of fleshless skin.

  The skull has sutures: one, of circular form, in the case of women; in the case of men, as a general rule, three meeting at a point. Instances have been seen of a man’s [5] skull devoid of suture altogether. In the skull the middle line, where the hair parts, is called the crown. In some cases the parting is double; that is to say, some men are double-crowned, not in regard to the bony skull, but in consequence of the parting of the hair.

  8 · The part that lies below the skull is called the face: but in the case of man [10] only, for the term is not applied to a fish or to an ox. In the face the part below the sinciput and between the eyes is termed the forehead. When men have large foreheads, they are slow; when they have small ones, they are quickly moved; when they have broad ones, they are apt to be distraught; when they have foreheads rounded, they are quick-tempered.9

  9 · Underneath the forehead are two eyebrows. Straight eyebrows are a sign [15] of softness of disposition; such as curve in towards the nose, of harshness; such as curve out towards the temples, of humour and dissimulation.

  Under the eyebrows come the eyes. These are naturally two in number. Each of them has an upper and a lower eyelid, and the hairs on the edges of these are termed eyelashes. The inner part of the eye includes the moist part whereby vision is [20] effected, termed the pupil, and the part surrounding it called the iris; the part outside this is the white. A part common to the upper and lower eyelid is a pair of nicks, one in the direction of the nose, and the other in the direction of the temples. When these are long they are a sign of bad disposition; if the side toward the nostril be fleshy, as in the case of kites,10 they are a sign of dishonesty. [25]

  All the other animals are provided with eyes, excepting the ostracoderms and other imperfect creatures; at all events, all viviparous animals have eyes, with the exception of the mole. And yet one might assert that, though the mole has not eyes in the full sense, yet it has eyes in a kind of way. For in point of fact it cannot see, [30] and has no eyes visible externally; but when the outer skin is removed, it is found to have the place where eyes are usually situated, and the black parts of the eyes rightly situated, and all the place that is usually devoted on the outside to eyes: showing that the parts are stunted in development, and the skin allowed to grow over.

  10 · Of the eye the white is pretty much the same in all creatures; but what is called the iris differs. In some it is black, in some
distinctly blue, in some [492a1] greyish-blue, in some greenish; and this last colour is the sign of an excellent disposition, and is particularly well adapted for sharpness of vision.

  Man is the only, or nearly the only, creature, that has eyes of diverse colours. [5] The others have eyes of one colour only. Some horses have blue eyes.

  Of eyes, some are large, some small, some medium-sized; of these, the medium-sized are the best. Moreover, eyes sometimes protrude, sometimes recede, sometimes are neither protruding nor receding. Of these, the receding eye is in all animals the most acute; but the last kind are the sign of the best disposition. Again, [10] eyes are sometimes inclined to blink, sometimes to stare, and sometimes neither. The last kind are the sign of the best nature, and of the others, the latter kind indicates impudence, and the former indecision.

  11 · Furthermore, there is a portion of the head, whereby an animal hears, a part incapable of breathing, the ear. For Alcmaeon is mistaken when he says that goats inspire through their ears. Of the ear one part is unnamed, the other part is [15] called the lobe; and it is entirely composed of gristle and flesh. The ear is constructed internally like the trumpet-shell, and the innermost-bone is like the ear itself, and into it at the end the sound makes its way, as into a jar. This does not communicate by any passage with the brain, but does so with the palate, and a vein [20] extends from the brain towards it. The eyes also are connected with the brain, and each of them lies at the end of a little vein.11 Of animals possessed of ears man is the only one that cannot move this part. Of creatures possessed of hearing, some have [25] ears, whilst others have none, but merely have the passages for ears visible, as, for example, feathered animals or animals with horny tessellation.

  Viviparous animals, with the exception of the seal, the dolphin, and those others which after a similar fashion to these are cetaceans, are all provided with ears; [for the shark-kind are also viviparous. But man alone does not move his ears. [30] Now, the seal has the passages visible whereby it hears; but the dolphin can hear, but has no ears. All other animals can move them.]12 And the ears lie on the same circumference as the eyes, and not in a plane above them as is the case with some quadrupeds. Of ears, some are smooth, some are shaggy, and some are of medium texture; the last kind are best for hearing, but they serve in no way to indicate [492b1] character. Some ears are large, some small, some medium-sized; again, some stand out far, some not at all, and some take up a medium position; of these the medium sort are indications of the best disposition, while the large and outstanding ones indicate a tendency to irrelevant talk or chattering. The part between the eye, the ear, and the crown is termed the temple.

  [5] Again, there is a part of the countenance that serves as a passage for the breath, the nose. For a man inhales and exhales by this organ, and sneezing is effected by its means—this is an outward rush of collected breath, and is the only mode of breath used as an omen and regarded as supernatural. Both inhalation and exhalation go right on towards the chest; and with the nostrils alone and separately [10] it is impossible to inhale or exhale, owing to the fact that the inspiration and respiration take place from the chest along the windpipe, and not by any portion connected with the head; and indeed it is possible for a creature to live without using its nose.

  Again, smelling takes place by means of the nose—that is, perception of odour. [15] And the nostril admits of easy motion, and is not, like the ear, intrinsically immovable. A part of it, composed of gristle, constitutes a septum, and part is an open passage; for the nostril consists of two separate channels. The nostril of the elephant is long and strong, and the animal uses it like a hand; for by means of this organ it draws objects towards it, and takes hold of them, and introduces its food [20] into its mouth, whether liquid or dry food, and it is the only living creature that does so.

  Furthermore, there are two jaws; the front part of them constitutes the chin, and the hinder part the cheek. All the animals move the lower jaw, with the exception of the river-crocodile; this creature moves the upper jaw only.

  [25] Next after the nose come two lips, composed of flesh, and facile of motion. The mouth lies inside the jaws and lips. Parts of the mouth are the roof and the pharynx.

  The part that is sensible of taste is the tongue. The sensation has its seat at the tip—if something is placed on the flat surface of the organ, the taste is less. The tongue can also perceive everything that flesh in general can—e.g. hardness, or warmth and cold, in any part of it, just as it can appreciate taste. The tongue is [30] sometimes broad, sometimes narrow, and sometimes of medium width; the last kind is the best and the clearest. Moreover, the tongue is sometimes loosely hung, and sometimes fastened: as in the case of those who mumble and who lisp.

  The tongue consists of flesh, soft and spongy, and the so-called epiglottis is a part of this organ.

  That part of the mouth that splits into two bits is called the tonsils; that part [493a1] that splits into many bits, the gums. Both the tonsils and the gums are composed of flesh. In the gums are teeth, composed of bone.

  Inside the mouth is another part, shaped like a bunch of grapes, a pillar streaked with veins. If this pillar gets moistened and inflamed it is called the uvula, and it then has a tendency to bring about suffocation.13

  12 · The neck is the part between the face and the trunk. [Of this the front [5] part is the larynx and the back part the gullet.]14 The front part, composed of gristle, through which respiration and speech is effected, is termed the wind-pipe; the part that is fleshy is the gullet, inside just in front of the chine. The part to the back of the neck is the shoulder-point.

  These then are the parts to be met with before you come to the thorax. [10]

  To the trunk there is a front part and a back part. Next after the neck in the front part is the chest, with a pair of breasts. To each of the breasts is attached a nipple, through which in the case of females the milk percolates; and the breast is soft. Milk is found at times in the male; but with the male the flesh of the breast is [15] tough, with the female it is spongy and porous.

  13 · Next after the thorax and in front comes the stomach, and its root the navel. Underneath this root the bilateral part is the flank; the undivided part below the navel is the abdomen, the extremity of which is the region of the pubes; and above the navel the hypochondrium; the part common to the hypochondrium and [20] the flank is the gut-cavity.

  Serving as a brace-girdle to the hinder parts is the pelvis, and hence it gets its name (ὀσφύς), for it is symmetrical (ἰσoφυές) in appearance; of the fundament the part for resting on is termed the buttock, and the part whereon the thigh pivots is termed the socket.

  The womb is a part peculiar to the female; and the penis is peculiar to the male. [25] This latter organ is external and situated at the extremity of the trunk; it is composed of two separate parts: of which the extreme part is fleshy, hardly alters in size, and is called the glans; and round about it is a skin devoid of any specific title, which never grows together again if it is cut any more than does the jaw or the eyelid. And the connexion between the latter and the glans is called the frenum. The [30] remaining part of the penis is composed of gristle; it is easily susceptible of enlargement; and it protrudes and recedes in the opposite way to that of the cat.15 Underneath the penis are two testicles, and the integument of these is a skin that is termed the scrotum.

  [493b1] Testicles are not identical with flesh, and are not altogether diverse from it. But by and by we shall treat in an accurate way regarding all such parts.

  14 · The privy part of the female is in character opposite to that of the male. In other words, the part under the pubes is hollow, and not, like the male organ, protruding. Further, there is an urethra outside the womb which serves as a passage [5] for the sperm of the male, and as an outlet for liquid excretion to both sexes.

  The part common to the neck and chest is the throat; the armpit is common to side, arm, and shoulder; and the groin is common to thigh and abdomen. The part i
nside the thigh and buttocks is the perineum, and the part outside the thigh and [10] buttocks is the hypoglutis.

  The front parts of the trunk have now been enumerated.

  The part behind the chest is termed the back.

  15 · Parts of the back are a pair of shoulder-blades, the back-bone, and, underneath on a level with the stomach in the trunk, the loins. Common to the upper and lower part of the trunk are the ribs, eight on either side, for as to the so-called [15] seven-ribbed Ligyans we have not received any trustworthy evidence.

  Man, then, has an upper and a lower part, a front and a back part, a right and a left side. Now the right and the left side are pretty well alike in their parts and [20] identical throughout, except that the left side is the weaker of the two; but the back parts do not resemble the front ones, neither do the lower ones the upper: only that these upper and lower parts may be said to resemble one another thus far, that, if the face be plump or meagre, the abdomen is plump or meagre to correspond; and that the legs correspond to the arms, and where the upper arm is short the thigh is [25] usually short also, and where the feet are small the hands are small correspondingly.

  Of the limbs, one set, forming a pair, is arms. To the arm belong the shoulder, upper-arm, elbow, forearm, and hand. To the hand belong the palm, and the five fingers. The part of the finger that bends is the knuckle, the part that is inflexible is the phalanx. The thumb is single-jointed, the other fingers are double-jointed. The [30] bending both of the arm and of the finger takes place inwards in all cases; and the arm bends at the elbow. The inner part of the hand is the palm, and is fleshy and divided by joints: in the case of long-lived people by one or two extending right [494a1] across, in the case of the short-lived by two, not so extending. The joint between hand and arm is the wrist. The outside or back of the hand is sinewy, and has no specific designation.
