ing themselves. Hence, thougli it is cer- 

 tain tliat tlie most voluminous and, perhaps, 

 the most comprehensive results, and those 

 resulting from the performance of coherent 

 experiments extending through a long series 

 of years, will come from the great centers 

 of research, there is no reason why qualita- 

 tive results equal to the best may not con- 

 tinue to come, as they have in the past, 

 from isolated workers, to the rounding out 

 and completion of whose studies the facili- 

 ties of the larger institutions will be more 

 and more applicable as the problems of 

 equipment are worked out.

AMERICAN ASSOCIATION FOB THE ADVANCE- 

 MENT OF SCIENCE. 



SECTION E.— GEOLOGY AND GEOGRAPHY. 



Section E of the American Association 

 this year virtually included the Geological 

 Society of America. The latter organiza- 

 tion held only a short meeting for routine 

 business on the Saturday evening previous 

 to the meeting of the American Associa- 

 tion, and referred all its papers to Section 

 E of the A. A. A. S. The total number of 

 papers offered in Section E was 42. The 

 last day of the meeting the Section was di- 

 vided into two subsections, one dealing with 

 Pleistocene Geology, and the other taking 

 the remainder of the field of the science. 

 Even with this division, the time did not 

 suffice for the full reading of all the papers, 

 and a considerable number of papers whose 

 authors were absent were read by title. 

 While none of the papers recorded any 

 discoveries of epoch-making significance, 

 nearly all of them contained the results of 

 solid and valuable work, contributing, in 

 an important degree, to the advancement 

 of science. 



The following is a list of the papers 

 presented: —
