size to the Bison priscus of the old world as to leave little reason for 
questioning its distinctness. 
For notes on the Osteology of Bison antiquus, and a comparison of 
the remains of B. antiquus and B. latifrons, reference may also be made 
to a memoir by Alban Stevvart*in which he discusses the wide geograph- 
ical distribution of B. antiquus, showing that the animal had a range 
over the greater part of North America.

The meeting of the American Association for the Advancement of 
Science, held in Boston, under the presidency of Prof. F. W. Putnam, 
on August 22d to the 27th of this year, the fiftieth anniversary since 
the formation of this Association, was one of the most interesting and 
successful in its history. The enrolled attendance was 903, represent-

Britain, France, New South Wales, and Japan. The number of new 
members elected was 273, bringing the membership up to about 1,900. 
The number of papers presented was 443, of which 55 were read in 
the sessions of Section E (Geology and Geography), as hereafter 
noted. 
By the invitation of Section E, meetings of the Geological Society 
of America and the National Geographic Society were held with this 
Section, the former in three sessions on Tuesday forenoon, afternoon,

final session on Friday forenoon, which was held in the geological 
lecture room of the Museum of Comparative Zoology, in Cambridge. 
The address by the vice president of Section E, Prof. Herman L. 
Fairchildj of Rochester, N. Y., on "Glacial Geology in America,"

A. S. Packard, of Providence, R. I., vice president of Section F 
(Zoology), entitled, "A Half-century of Evolution, with Special Ref- 
erence to the Effects of Geological Changes on Animal Life," pub-
