Excerpt from Southern Medical Journal, Vol. 12: October, 1919 HE history of medicine reveals constant changes with periods of marked progress. Compara tively, no era in the past can by any means equal the present in the rapid progress which is being made in true scientific medicine. This has been made possible bv the achievements in the collateral branches, by the many new and applied clinico-labora tory methods, the introduction of various instruments of precision, and the admirable modern clinical laboratories with their scores of earnest, sincere and determined workers, inspired with the spirit of original investiga tion. Truly, the impossibilities or the day-dreams of yester day have become the demonstrated and accepted facts of today. Compared with this marvelous progress, the S present is equally remarkable for the varied and diver siiied activities in the various fields of medicine, each manifest in some locality most favorable to the growth of science by some particularly qualified individual or group of workers.
