DOCTORATES CONFERRED IN BOTANY BY AMERI- 
CAN UNIVERSITIES IN i912 
For the past fifteen years it has been the custom of Science 
to publish annually records of the doctorates of philosophy con- 
ferred by American Universities. The total number of docto- 
rates conferred in all subjects during the first five of these years 
was 233. During the last ten years the number more than 
doubled, being 492. According to the last statement (Science N.S. 
36: 129-139. 2 Ag 1912), the number of degrees conferred 
in the natural and exact sciences increases more rapidly than 
in other subjects. In this group chemistry has always led in 
the total number of degrees conferred, with physics second, and, 
until 1912, zoology third. During the present year, however, more 
degrees were conferred in botany than in zoology. Agriculture 
and bacteriology are not considered as “botany,” in making up 
this total. 
Out of a total of 30 degrees conferred in botany in 1912, 
the University of Chicago conferred 7, Columbia 3, Cornell 6, 
and California, Johns Hopkins, Michigan, Indiana, and Iowa, 2 
each.
