THE MEDICAL PROFESSION AND THE 

 ISSUES WHICH CONFRONT IT.^ 



The American Medical Association be- 

 gins its fifth-seventh annual session under 

 the most auspicious circumstances. After 

 an interval of forty-one years it again meets 

 in Boston, the guest of this great common- 

 wealth which has ably upheld the highest 

 medical traditions since the founding of 

 New England. 



Another cause of felicitation — the sec- 

 tional differences in New York have been 

 overcome and the Empire State for the 

 first time in twenty-five years presents a 

 unified delegation. 



The house of delegates of the American 

 Medical Association (which technically is 

 the American Medical Association) repre- 

 sents directly about 55,000 and indirectly 

 the 120,000 regular practitioners of medi- 

 cine in the United States. The official 

 organ, the Journal, reaches each week over 

 43,000 subscribers, and under the able 

 editorship of Dr. George H. Simmons, has 

 become the leading professional magazine 

 in the world. 



The medical profession is to be congratu- 

 lated upon these evidences of a useful or- 

 ganization, biit much remains to be done. 

 In his individual capacity the medical man 

 has not been found wanting. Go where 

 you will in civilized lands, you will find 

 the doctor, self-sacrificing, patient and 

 charitable, upholding the honor and 

 dignity of his noble calling. Collectively, 

 medical men do not have the influence
