'Considering the obscurity which prevails as to the cause of the greater part of diseases, and the great probability that many among them owe their origin to the presence of chemical agents dispersed in the atmosphere, it becomes the duty of medical men and physiologists, who interest themselves in the progress of their science, to seize earnestly all the means by which they may hope to arrive at more exact notions upon the relations which exist between abnormal physiological phenomena and external circumstances.' Such is a summary of M.
