Animal Substances being already assimilated, are more easily transmutable into other Animals, and therefore more nourishing than Vegetables; accordingly we find such Animals as are nourished by animal Food, to be more couragious, robust, active, bold, strong, than those which are nourished by Vegetables only. And even in Men, who have proper Organs for digesting both animal and vegetable Food, and consequently by Nature designed to use both, we find a remarkable Difference according to their Diet. The Inhabitants of fishing Towns, who may well be supposed to feed thereon, are strong, nervous and prolifick; and their Discharges, especially their Sweat, are often attended with a very strong rancid Smell. The Difference between these People, and some poor Peasants in the Country, who have no other than vegetable Food, is too obvious to mention. As to the Preparation of animal Diet, by the Arts of Cookery, for Use, it is needless to repeat what was before said under this Head in relation to Vegetables, the Manner being pretty much the same. I shall only just observe, that in boiling, the Salts and a good Portion of Oyl is dissolved, and attenuated in the Decoction, which makes the Decoction it self very nourishing; the animal Substance it self is much relaxed and softned, so that it may almost all be reduced to a Jelly or thick Oyl; by roasting, the Salts are more brought into Action, and the fluid Parts lessened; so that what remains is more highly impregnated therewith; in baking no Part evaporates, but both Salts and Oyls are loosened and exalted by the Heat in the Oven; these Differences are observable by the Taste, affect the digestive Powers in different Degrees, and are usefully attended to, in many different Habits of the human Body, too tedious now to be enumerated. It is to be observed here (as before concerning Vegetables) that the nearer the nutritious Juices are to their Roots, the more they partake of the Nature of their Origine; but the more they are mixed with animal Juices, and the greater Number of animal Circulations they pass through, the more they acquire an animal Nature. The Chyle in Animals feeding upon Vegetables is Acid, and generally speaking it is so in Men, because their Diet is more so than otherwise. The Milk is less Acid than the Chyle, but turns perfectly so by standing. In the Blood this Tendency is lost, and the Salts from fixed become volatile. But there are Juices in animal Bodies, that have Salts of a much higher Degree of Volatility than the Blood, but when they arrive at too high a state of Alkalescence, they are discharged generally by Urine, or some other Excretion.
