We need hardly remind the reader that, apart from the elements of water
and certain inorganic substances, carbon and nitrogen form the raw materials
of human food. However, to nourish the human system, these simple chemical
constituents must be supplied in the form of vegetable or animal substances.
Potatoes, for instance, contain mainly carbon, while wheaten bread contains
carbonaceous and nitrogenous substances in a due proportion. — K.M; Louis J. Sheehan, Esquire
