638 Proceedings of Societies. [ October, 
the case ten years ago, that exception had been taken to scarcely a sin- 
gle point. Unquestionably the most remarkable paper presented before 
this section was that by Dr. W. K. Brooks, of Boston, on proposed mod- 
ifications in Darwin’s theory of pangenesis, but space will not here per- 
mit a fair abstract; simpler even than that proposed by Darwin, it ex- 
plained many points which were not met by the latter. One hundred 
and seventy-four papers were presented to the standing committee, of 
which all but about a dozen were read in full or by title; and these 
were almost equally divided between the physical and natural history 
sections. 
The association was invited to meet at Nashville, Atlanta, and St. 
Louis; the first place was chosen, and August 29, 1877, selected as the 
opening day ; the following are the officers elect: President, Professor 
Simon Newcomb, of Washington ; Vice-Presidents: Section A, Professor 
E. C. Pickering, of Boston; Section B, Professor O. C. Marsh, of New 
Haven ; Permanent Secretary, F. W. Putnam, of Salem; General Sec- 
retary, A. R. Grote, of Buffalo ; Secretary Section A, Dr. H. C. Bolton, 
of New York; Section B, Lieutenant W. H. Dall, of Washington ; 
Treasurer, W. S. Vaux, of Philadelphia ; Chairman Subsection of Chem- 
istry, Professor N. T. Lupton, of Nashville ; Subsection of Microscopy, 
Dr. R. H. Ward, of Troy; Subsection of Anthropology, Professor 
Daniel Wilson, of Toronto. .
