UNDERGRADUATE COURSE: The course of instruction extends over four annual sessions, the 

 work so graded that the first and second years are largely occupied by the fundamental medical subjects. The 

 third and fourth years are largely devoted to the practical branches, prominence being given to clinical instruction, 

 and the classes sub-divided into small groups so that the Individual students are brought into particularly close and 

 personal relations with the instructors and with the patients, at the bedside and in the operating room. It is strongly 

 recommended that after graduation further hospital work be undertaken by the members of the class ; and at least 

 90 per cent, as a rule attain by competitive examination or by appointment positions as internes in hospitals in this 

 city or elsewhere.
