Philosophy of Eating, 1868

1868. We have excellent practical treatises on agriculture and horticulture, and every intelligent farmer or gardener may learn what element is deficient, in order to successfully cultivate his grapes, his vegetables, or his grains; and having also chemical analyses of these fruits and grains, and of the materials from which to obtain his deficient elements, he has the means of adapting his soil to all desirable productions. So perfectly ignorant are people generally of the laws of nature, that they give their pigs the food which their children need to develop muscle and brain, and give their children what their pigs need to develop fat. To supply this deficiency in practical science, and to correct these erroneous and dangerous habits of society, is the object of this treatise.
