It has been observed that one's nose is never so happy as when thrust into the affairs of others from which some physiologists have drawn the inference that the nose is devoid of the sense of smell.
As a progressive discipline [biochemistry] belongs to the present century. From the experimental physiologists of the last century it obtained a charter, and, from a few pioneers of its own, a promise of success; but for the furtherance of its essential aim that century left it but a small inheritance of facts and methods. By its essential or ultimate aim I myself mean an adequate and acceptable description of molecular dynamics in living cells and tissues.
