cerned, and the comparison with previous 

 years indicates that conditions affecting doc- 

 torates have regained a normal state. There 

 has been no increase in the number conferred, 

 nor any considerable decrease. 



In 1920 there were 328 doctorates conferred 

 in the natural and physical sciences by 31 in- 

 stitutions. In 1916 there were 332 conferred 

 by 28 institutions. It is interesting to note 

 that the small decrease in the number of 

 degrees conferred is practically equalled by 

 the small increase in institutions conferring 

 them. Those institutions which have always 

 been at the head of the list have changed their 

 order in some cases, but are still leading. 

 However, the degrees seem to be more widely 

 distributed than formerly. The University of 

 Chicago continues to confer the largest num- 

 ber of degrees, while Cornell University takes 

 second place. As usual, the eastern universi- 

 ties lead in numbers conferred, though the 

 western and middle western institutions fol- 

 low very closely with only 14 less. Johns 

 Hopkins University dropped from 23 in 1915 

 and 23 in 1916 to 17 in 1920, and Harvard 

 rose from 16 in 1916 to 28 in 1920. Wis- 

 consin and Illinois have taken their places 

 in the first group, with 24 and 22 degrees 

 respectively. There were 14 universities con- 

 ferring degrees in the past which conferred 

 none this year. 



Chemistry continues to head the list of sub- 

 jects in which the doctorates were conferred, 

 though with not so large a number as in 1916, 

 nor so great a per cent, of the total. In 1916 

 there were 115 conferred in chemistry and in 

 1920 there were 96. Small gains in many of 

 the other sciences bring up the total. The 

 most noticeable gain is in psychology, which 

 has risen from 22 in 1915, and 19 in 1916 to 

 40 in 1920. No doctorates were conferred 

 specifically in paleontology, mineralogy, metal- 

 lurgy or meteorology. 



A list of the names of the recipients of 

 the doctorates with the titles (sometimes 

 abridged) of their theses has been made, 

 classified by the subject in which the degree 

 was conferred, and grouped imider the subject 

 according to the university conferring them.
