Excerpt from Experiments on the Metabolism of Matter and Energy in the Human Body The ultimate purpose of the research to which these experiments belong is the study of some of the fundamental laws of nutrition. The plan Of the whole inquiry is based upon the principle that the chemical and physical changes which take place within the body, and to which the general term metabolism is applied, occur in obedience to the laws of the conservation of matter and energy. That the law of the conservation of matter applies within the living organism no one would question. It might seem equally certain that the metabolism of energy within' the body takes place in accordance with the law of the conservation of energy. The quantitative demonstration is, however, desirable, and an attested method for such demonstration is of funda mental importance for the study of the general laws of metabolism of both matter and energy.
