THE EARLY PRESIDENTS OF THE AMERICAN 
ASSOCIATION.* 
I. 
For a second time in its history the Sec- 
tion on Social and Heonomic Science in the 
American Association for the Advancement 
of Science has chosen for its presiding offi- 
cer one whose early training was that of a 
chemist. It had been my hope to present 
before you an address that should treat of 
certain phases of the development of indus- 
trial chemistry in the United States. The 
suggestion, however, made at the mid- 
winter meeting in New York by Professor 
Putnam, that I prepare an account of the 
early history of the Association, appealed 
to me so strongly that I was very glad to 
yield to the wishes of the Council, who 
promptly accepted the recommendation of 
our distinguished President, and, therefore, 
I have the honor of addressing you on 
The Early Presidents of the American 
Association. 
HISTORY. 
The American Association for the Ad- 
vancement of Science came into formal ex- 
istence in the city of Philadelphia, on Sep- 
tember 20, 1848. The prevalent fondness 
for genealogical research affords us an ex-
