TEE CABEEB OF THE INVESTIGAIOB^ 

 Scarcely more than a generation ago 

 the graduate in medicine had his profes- 

 sional career marked out for him with a 

 fair degree of definiteness. Private prac- 

 tise, as exemplified in the functions of the 

 family physician, offered, apart from sur- 

 gery, almost the only opportunity for the 

 use of a medical training. During the 

 past thirty years how extensively have 

 medical activities become diversified. The 

 paths of service that now invite the young 

 physician are so varied that every grad- 

 uate should be able to select a way for 

 employing his peculiar powers to the best 

 advantage. Quite apart from the conven- 

 tional career of the physician, the surgeon, 

 or the different specialists, are the oppor- 

 tunities for usefulness in the widespread 

 movements which are socializing medicine. 

 In professional service at hospitals and 

 sanatoriums important work can be done; 

 in boards of health, municipal, state and 

 national ; in public propaganda for temper- 

 ance, for the prevention of infant mor- 

 tality, for industrial hygiene, for the care 

 of school children; in the campaigns 

 against tuberculosis and venereal disease 

 — in all these activities the possibilities of 

 applying a medical education usefully to 

 social needs are numerous and are yearly 

 increasing. 



Still another new career open to the 

 young graduate is that of research in the 

 medical sciences. For attracting young 

 men into scholarly careers the medical sci- 

 ences are, I suspect, at some disadvantage 

 compared with other natural sciences.
