25. A Monograph of the Helices inhabiting the United States. By 
Amos Binney, M. D. Catalogue of the Library—Donors to the 
Library—Donations—Index. These papers are all valuable and of 
a highly scientific character. Mr. Binney’s Monograph of the He- 
lices is peculiarly interesting to American conchologists, as clearing 
up much uncertainty that hung over many of the species—restoring 
them in some cases to their original discoverer, and presenting us the 
whole of this natural family at one view. All the other papers are 
interesting in this way, and will no doubt receive the attention they 
' deserve. 
2. Catalogue of the Library of the Academy of Natural Sci- 
ences of Philadelphia. Phil. J. Dobson. 1837. 8vo. pp. 300.— 
This is an important document, inasmuch as the library is the largest 
and the most important on its own peculiar branches in this country. 
What is of more interest, however, is that the whole library, with 
the exception of five hundred and fifty eight volumes, is the result 
of the munificence of one individual—the venerable Wm. Maciure, 
now residing in Mexico, the pioneer of American Geology, and ever 
the most efficient patron and still a laborer in the fields of science. 
It has been owing chiefly to his efficient aid that the library of the 
Philadelphia Academy has been’ formed, while its members have 
labored ably and faithfully, and the result of their labors may be 
seen in the valuable Journal of the transactions of the society noticed 
frequently in our pages. 3 
It appears from the report prefixed to this catalogue that the 
library contains exclusive of tracts, six thousand eight hundred and 
ninety volumes, which may be classed according to size in the fol- 
lowing manner: 
Folio, - - - - 674
