CHAP. 77.—THE DIAPHRAGM. THE NATURE OF LAUGHTER.
The entrails of serpents and lizards are of remarkable length. It is related that—a most fortunate omen—Cæcina of Volaterræ beheld two dragons arising from the entrails of the victim; and this will not be at all incredible, if we are ready to believe that while King Pyrrhus was sacrificing, the day upon which he died, the heads of the victims, on being cut off, crawled along the ground and licked up their own blood. In man, the entrails are separated from the lower part of the viscera by a certain membrane, which is called the “præcordia,”[288] because it is extended in front of the heart; the Greeks have given it the name of “phrenes.” All the principal viscera have been enclosed by Nature, in her prudent foresight, in their own peculiar membranes, just like so many sheaths, in fact. With reference to the diaphragm, there was a peculiar reason for this wise provision of Nature, its proximity to the guts, and the chances that the food might possibly intercept the respiration. It is to this organ that is attributed quick and ready wit, and hence it is that it has no fleshy parts, but is composed of fine sinews and membranes. This part is also the chief seat of gaiety of mind, a fact which is more particularly proved by the titillation of the arm-holes, to which the midriff extends; indeed, in no part of the body is the skin more fine; for this reason it is, also, that we experience such peculiar pleasure in scratching the parts in its vicinity. Hence it is, that in battles and gladiatorial combats, many persons have been known to be pierced through the midriff, and to die in the act of laughing.[289]
CHAP. 78.—THE BELLY: ANIMALS WHICH HAVE NO BELLY. WHICH ARE THE ONLY ANIMALS THAT VOMIT. In those animals which have a stomach, below the diaphragm the belly is situate. In other animals it is single, but in those which ruminate it is double; in those, again, which are destitute of blood, there is no belly, for the intestinal canal commences in some of them at the mouth, and returns to that part, as is the case with the sæpia and the polypus. In man it is connected with the extremity of the stomach, and the same with the dog. These are the only creatures that have the belly more narrow at the lower part; hence it is, too, that they are the only ones that vomit, for on the belly being filled, the narrowness at its extremity precludes the food from passing; a thing that cannot possibly be the case with the animals in which the belly is more capacious at the extremity, and so leaves a free passage for the food to the lower parts of the body. CHAP. 79.—THE SMALL GUTS, THE FRONT INTESTINES, THE ANUS, THE COLON. THE CAUSES OF THE INSATIATE VORACITY OF CERTAIN ANIMALS.
After the belly we find in man and the sheep the “lactes,”[290] the place of which in other animals is occupied by the “hillæ:”[291] it is through these organs that the food passes. We then find the larger intestines, which communicate with the anus, and which in man consist of extremely sinuous folds. Those animals which have the longest intestinal canal, are the most voracious; and those which have the belly the most loaded with fat, are the least intelligent. There are some birds, also, which have two receptacles; the one of which is the crop, in which they stow away the food which they have just swallowed, while the other is the belly, into which they discharge the food when it is duly prepared and digested; this is the case with the domestic fowl, the ring-dove, the pigeon, and the partridge. The other birds are in general destitute of crop, but then they have a more capacious gorge, the jackdaw, the raven, and the crow, for instance: some, again, are constituted in neither manner, but have the belly close to the gorge, those, for instance, which have the neck very long and narrow, such as the porphyrio.[292]
In the solid-hoofed animals the belly is rough and hard, while in some land animals it is provided with rough asperities like teeth,[293] and in others, again, it has a reticulated surface like that of a file. Those animals which have not the teeth on both sides, and do not ruminate, digest the food in the belly, from whence it descends to the lower intestines. There is an organ in all animals attached in the middle to the navel, and in man similar in its lower part to that of the swine, the name given thereto by the Greeks being “colon,” a part of the body which is subject to excruciating pains.[294] In dogs this gut is extremely contracted, for which reason it is that they are unable to ease it, except by great efforts, and not without considerable suffering. Those animals with which the food passes at once from the belly through the straight intestine, are of insatiate appetite, as, for instance, the hind-wolf,[295] and among birds the diver. The elephant has four[296] bellies; the rest of its intestines are similar to those of the swine, and the lungs are four times as large as those of the ox. The belly in birds is fleshy, and formed of a callous substance. In that of young swallows there are found little white or pink pebbles, known by the name of “chelidonii,” and said to be employed in magical incantations. In the second belly of the heifer there is a black tufa found, round like a ball,[297] and of no weight to speak of: this, it is generally thought, is singularly efficacious in laborious deliveries, if it happens not to have touched the ground.
CHAP. 80.—THE OMENTUM: THE SPLEEN; ANIMALS WHICH ARE WITHOUT IT. The belly and the intestines are covered with a caul known as the “omentum,” consisting of a fatty, thin membrane; except in the case of those animals which are oviparous. To this membrane is attached the spleen, which lies on the left side, and opposite the liver: sometimes, indeed, it changes place with the liver, but such a case is looked upon as nothing less than a prodigy. Some persons imagine that a spleen of extremely diminutive size exists in the oviparous animals, as also in serpents; at all events, it is to be detected in the tortoise, the crocodile, the lizard, and the frog; though it is equally certain that it does not exist in the bird known as the “ægocephalos,”[298] nor yet in those animals which are destitute of blood. The spleen sometimes offers a peculiar impediment in running, for which reason the region of the spleen is cauterized[299] in runners who are troubled with pains there. It is said also, that if the spleen is removed[300] by an incision, animals may survive. There are some persons who think that with the spleen man loses the power of laughing, and that excessive laughter is caused by the overgrowth of it. There is a territory of Asia, known as Scepsis,[301] in which it is said that the spleen of the cattle is remarkably small, and that from thence it is that remedies for diseases of the spleen have been introduced.
CHAP. 81.—THE KIDNEYS: ANIMALS WHICH HAVE FOUR KIDNEYS. ANIMALS WHICH HAVE NONE. About Briletum and Tharne[302] the stags have four kidneys: while, on the other hand, those animals which have wings and scales have[303] none. The kidneys adhere to the upper part of the loins. Among all animals, the kidney on the right side is more elevated than the other, less fat, and drier. In both kidneys there is a certain streak of fat running from the middle, with the sole exception of those of the sea-calf. It is above the kidneys, also, that animals are fattest, and the accumulation of fat about them is often the cause of death in sheep. Small stones are sometimes found in the kidneys. All quadrupeds that are viviparous have kidneys, but of those which are oviparous the tortoise is the only one that has them; an animal which has all the other viscera, but, like man, has the kidneys composed, to all appearance, of several kidneys, similar to those of the ox. Nature has placed the breast, or, in other words, certain bones, around the diaphragm and the organs of life, but not around the belly, for the expansion of which it was necessary that room should be left. Indeed, there is no animal that has any bones around the belly. Man is the only creature that has a broad breast; in all others it is of a carinated shape, in birds more particularly, and most of all, the aquatic birds. The ribs of man are only eight in number; swine have ten, the horned animals thirteen, and serpents thirty.
