REPORT OF THE SECRETARY. 61 



o 



Work of the Society. — The following table includes the papers and ab- 

 stracts of papers, of whatever length, printed in the four completed 

 volumes of the Bulletin. The few titles not accompanied by descriptive 

 matter or discussion are not included. As such a classification of papers, 

 many of them being of a general or composite character, must vary 

 somewhat with the individual judgment, the table cannot be regarded 

 as wholly accurate. It may indicate approximately the attention given 

 to different branches of geologic science.
