Tue British Medical Journal states that 
during the summer school, Cambridge, Sir 
William Osler, on August 7, gave a sketch of

among the early colonists, tracing the influ- 
ence of Edinburgh and of John Hunter, and 
coming down to the New England group illus- 
trated by Jacob Bigelow and James Jackson. 
The second, French, period extended from 
1820 to 1860, when the influence of Laénnec 
and Louis was supreme; of the third, German, 
period extended from 1860 to 1890, the main 
features were specialism at the Vienna school, 
the teaching of Virehow and Koch, and the 
work of Traube in experimental medicine. 
The fourth period is the American, from 1890 
to the present day, its chief features being the 
reorganization of hospitals as integral parts 
of the university system, and unit and team 
work illustrated in the clinics of Cushing, 
Halsted and the Mayo brothers.
