"I will not bore you with chemical and physiological facts," continued Wanlee, "but you must know that the food which we take, in whatever form, resolves itself into what are called proximate principles- starch, sugar, oleine, flurin, albumen, and so on. These are selected and assimilated by the organs of the body, and go to build up the necessary tissues. But all these proximate principles, in their turn, are simply combinations of the ultimate chemical elements, chiefly carbon, nitrogen, hydrogen, and oxygen. It is upon these elements that we depend for sustenance. By the old plan we obtained them indirectly. They passed from the earth and the air into the grass; from the grass into the muscular tissues of the ox; and from the beef into our own persons, loaded down and encumbered by a mass of useless, irrelevant matter. The German chemists have discovered how to supply the needed elements in compact, undiluted form- here they are in this little box. Now shall mankind go direct to the fountainhead of nature for his aliment; now shall the old roundabout, cumbrous, inhuman method be at an end; now shall the evils of gluttony and the attendant vices cease; now shall the brutal murdering of fellow animals and brother vegetables forever stop- now shall all this be, since the new, holy cause has been consecrated by the lips I love!"
