ACADEMY OF NATURAL SCIENCES 
OF 
PHILADELPHIA. 
ANNUAL REPORTS. 
1897 . 
REPORT OF THE RECORDING SECRETARY. 
The average attendance at the meetings of the Academy during 
the past year has been 25. There has been no occasion of sufficient 
interest to fill the room and thus raise this average as has usually 
been the case in former years, while the separation of special inter¬

and Microscopical Section and, less frequently, that of the Mineral- 
ogical and Geological Section, have been productive of good re¬

Verbal communications have been made by Messrs. Rand, Sharp, 
Goldsmith, Pilsbry, J. C. Morris, Carter, Woolman, G. Vaux, Jr., 
S. Brown, Morsell, Skinner, Chapman, Calvert, Holman, Dixon, 
Heath, Keely, Conklin, Palmer, Kelly, Mercer, Schaeffer, Frazer, 
Allen, Peirce, Crawford, Stewart, Reese, C. Morris, Griffiths, Boyer, 
Wells, Garrison, Sullivan, Mrs. Bladen and Miss Walter. But few 
of these were reported by their authors for publication and they 
can, therefore, only be referred to in the written minutes of the 
Academy. 
Four hundred and eighty-four pages of the Proceedings illustrated 
by 13 plates, and 144 pages of the Journal with 17 plates, forming 
the first part of Volume XI, have been issued. As heretofore, we 
are indebted to Mr. Clarence B. Moore for the beautiful illustra-
