A PROBLEM IN AMERICAN ANTHROPOLOGY.* 
WHILE engaged in writing the address 
which I am to read to you this evening the 
sad news reached me of the death, on July 
31st, of our President of five years ago, 
Doctor D. G. Brinton. Although not un- 
expected, as his health had been failing 
since he was with us at the Boston meeting, 
where he took his always active part in 
the proceedings of Section H and gave his 
wise advice in our General Council, yet his 
death affects me deeply. Iwas writing on a 
subject we had often discussed in an earnest 
but friendly manner. He. believed in an 
all-pervading psychological influence upon 
man’s development, and claimed that Amer- 
ican art and culture were autochthonous, 
and that all resemblances to other parts of 
the world were the results of corresponding 
stages in the development of man; while I 
claimed that there were too many root 
coincidences, with variant branches, to be 
fully accounted for without also admitting 
the contact of peoples. Feeling his influ- 
ence while writing, I had hoped that he 
would be present to-night, for I am certain 
that no one would have more readily joined 
with me in urging a suspension of judg- 
ment, while giving free expression to opin- 
ions, until the facts have been worked over 
anew and more knowledge attained. 
* Address of the retiring President of the American 
Association for the Advancement of Science, given at 
Columbus on August 21, 1899.
