III. WHY DO HERDSMEN SET SALT BEFORE CATTLE? WHETHER (as many think) to nourish them the more, and fatten them the better? For salt by its acrimony sharpens the appetite, and by opening the passages brings meat more easily to digestion. Therefore Apollonius, Herophilus’s scholar, would not have lean persons, and such as did not thrive, be fed with sweet things and gruel, but ordered them to use pickles and salt things for their food, whose tenuity, serving instead of frication or sifting, might apply the aliment through the passages of the body. Or is it for health’s sake that men give sheep salt to lick, to cut off the redundance of nutriment? For when they are over fat, they grow sick; but salt wastes and melts the fat. And this they observe so well, that they can more easily flay them; for the fat, which agglutinates and fastens the skin, is made thin and weak by the acrimony. The blood also of things that lick salt is attenuated; nor do things within the body stick together when salts are mixed with them. Moreover, consider this, whether the cattle grow more fruitful and more inclined to coition; for bitches do sooner conceive when they are fed with salt victuals, and ships which carry salt are more pestered with mice, by reason of their frequent coition.
