Excerpt from Science, Vol. 20: A Weekly Journal Devoted to the Advancement of Science, Publishing the Official Notices and Proceedings of the American Association for the Advancement of Science; July-December, 1904 And so the situation remained until about 1860, when the views of Pasteur on alcoholic fermentation and the isolation by the German physiologists of several active soluble ferments or enzymes of the animal body began to attract wide attention and point the way toward an explanation of many processes taking place in the organ ism. With the growing recognition of the character and importance of the work of the enzymes I think we have the first real tangible evidence of the dependence of medicine on the new chemistry. The doc trine of the ferments as applied to the chemical changes taking place Within the body is one, apparently, of indefinite ex tension, and at the present day, 'after forty years of trial, it seems more than ever likely to hold its own and be capable of even wider development. In passing, I must add that it would not be fair to claim that the great advances just suggested were all due to the eiforts of chemists. On the contrary, many of 'themwere conceived and largely worked out by men who had been trained primarily in medicine rather than in chemistry.
