Book II Chapter 5

The differences between lard and suet correspond to differences of blood. For both are blood concocted¹ into these forms as a result of abundant nutrition, being that surplus blood that is not expended² on the fleshy part of the body, and is of an easily concocted and fatty character. This is shown by the unctuous³ aspect of these substances; for such unctuous aspect in fluids is due to a combination of air and fire. It follows from what has been said that no non-sanguineous animals have either lard or suet; for they have no blood. Among sanguineous animals those whose blood is dense⁴ have suet rather than lard. For suet is of an earthy nature, that is to say, it contains but a small proportion of water and is chiefly composed of earth; and this it is that makes it coagulate, just as the fibrous matter of blood coagulates, or broths⁵ which contain such fibrous matter. Thus it is that in those horned animals that have no front teeth in the upper jaw⁶ the fat consists of suet. For the very fact that they have horns and huckle-bones shows that their composition is rich in this earthy element; for all such appurtenances are solid and earthy in character. On the other hand in those hornless animals that have front teeth in both jaws⁷, and whose feet are divided into toes, there is no suet, but in its place lard; and this, not being of an earthy character, neither coagulates nor dries up into a friable⁸ mass.

Both lard and suet when present in moderate amount are beneficial; for they contribute to health and strength, while they are no hindrance⁹ to sensation. But when they are present in great excess, they are injurious and destructive. For were the whole body formed of them it would perish. For an animal is an animal in virtue¹⁰ of its sensory¹¹ part, that is in virtue of its flesh, or of the substance analogous¹² to flesh. But the blood, as before stated, is not sensitive; as therefore is neither lard nor suet, seeing that they are nothing but concocted blood. Were then the whole body composed of these substances, it would be utterly¹³ without sensation. Such animals, again, as are excessively fat age rapidly. For so much of their blood is used in forming fat, that they have but little left; and when there is but little blood the way is already open for decay. For decay may be said to be deficiency of blood, the scantiness¹⁴ of which renders it liable, like all bodies of small bulk, to be injuriously affected¹⁵ by any chance excess of heat or cold. For the same reason fat animals are less prolific¹⁶ than others. For that part of the blood which should go to form semen and seed is used up in the production of lard and suet, which are nothing but concocted blood; so that in these animals there is either no reproductive excretion at all, or only a scanty¹⁷ amount.
