THE AMERICAN MEDICAL ASSOCIATION: 

 ITS ORIGIN, PROGRESS AND PURPOSE.^ 



Both established usage and the by-laws 

 of this association require the presiding 

 officer to deliver annually an address touch- 

 ing such matters as he may deem of impor- 

 tance. In the early years of the associa- 

 tion the president's address was devoted 

 to an epitome of the progress of medical 

 science in its various departments during 

 the preceding year. Since distinguished, 

 orators are now selected annually to per- 

 form this important service, the president's 

 address may be more appropriately directed 

 to subjects relating to the general welfare 

 of the profession and to the purposes for 

 which this great organization was estab- 

 lished. 



The annual session of the American 

 Medical Association is always an occasion 

 of special moment and universal interest to 

 the medical profession of America. That 

 several thousand physicians from all sec- 

 tions of our broad country assemble an- 

 nually for the advancement of medical sci- 

 ence and the elevation of our profession is 

 a splendid testimonial to the earnestness of 

 professional achievement and aspiration. 

 The occasion can not but command the re- 

 spect of all Avho are concerned in the prog- 

 ress of science and the betterment of the 

 human race. The spirit which pervades 

 such an assemblage is the desire for im- 

 provement, for the increase of scientific re-

 session of the American Medical Association at 

 Portland, Oregon, July 11-^14, 1905. From The 

 Journal of the American Medical Association.
