"The vegetable stores up energy. It is from the vegetable world—the coal and the wood—that the energy is derived which runs our steam engines, pulls our trains, drives our steamships, and does the work of civilization. It is from the vegetable world that all animals, directly or indirectly, derive the energy which is manifested by animal life through muscular and mental work. The vegetable builds up, the animal tears down. The vegetable stores up energy; the animal expands energy. Various waste and poisonous products result from the manifestation of energy, whether by the locomotive or the animal. The working tissues of the animal are enabled to continue their activity only by the fact that they are continually washed clean by the blood, a never-ceasing stream flowing through and about them, carrying away the poisonous products resulting from their work as rapidly as they are formed. The venous blood owes its character to these poisons, which are removed by the kidneys, lungs, skin and bowels. The flesh of a dead animal contains a great quantity of these poisons, the elimination of which ceases at the instant of death, although their formation continues for some time after death. An eminent French surgeon recently remarked that ‘beef tea is a veritable solution of poisons.’"
