PLEISTOCENE PAPERS AT THE MADISON 
MEETINGS. 
A large proportion of the papers presented before both the 
Geological Society of America, in its meeting at Madison, Wis., 
August 15th and 16th, and Section E (Geolog} T and Geog- 
raphy) of the American Association for the Advancement of 
Science, which held its annual sessions in the same city Aug- 
ust 17th to 22d, related to Pleistocene geology, as the glacial and 
modified drift, the characters, methods of action, and effects of 
ancient and of now existing glaciers, and the probable causes 
of accumulation and departure of the Pleistocene ice-sheets. 
Notes of these papers, and of the accompanying discus-inn-. 
are here given in the order in which the papers were read.
