Sixth Annual Meeting of the Geological Society of 
America. 
This meeting was held Dec. 27-29. 1893, in Boston and Cam- 
bridge, Mass. Fifty-one fellows of the Society were in at- 
tendance, and fifty-nine papers were presented. The sessions 
of the opening and (dosing days were in the hall of the Boston 
Society of Natural History ; and those of Thursday, the 28th, 
were in the Harvard University museum, Cambridge. The 
president, Sir J. William Dawson, presided during the greater 
portion of the meeting, and by his quick wit and geniai man- 
ners contributed much toward the interest and pleasure of all. 
Prof. A\ r illiam H. Niles, president of the Boston Society of Nat- 
ural History, made a cordial address of welcome. He contrasted 
the time when Sir Charles Lyell visited Boston and the pres- 
ent time. Public feeling then was strongly opposed to the 
conclusions of geological investigation, but now they are gen- 
erally acknowledged to be for the best interests of humanity. 
The election of officers for 1894 was as follows : president, 
T. 0. Chamberlin, Chicago, 111.; vice-presidents, N. S. Shaler,
