Fine copy, and very scarce. 
The complete writings of, on the Conchology of the United States. Edited by 
W. G. Binney, Member of the Academy of Natural Sciences of Philadelphia. 
This work consists of 252 pages of text, and 75 plates, containing 323 figures. It 
includes all the descriptions of- genera and species ever published by Mr. Say, and also 
all his figures. It will therefore' be the first and only complete edition of Say’s Concho- 
logical Writings ever published, and the most extensive work on the general Conchology 
of the United States, since the greater number of known American species of mollusca 
were described by him. 
The compilation has been made from the following works : 
Nicholson’s Encyclopedia, American editions, with 4 plates. 
Philosophical Transactions of the Royal Society of London. 
Journal of the Academy of Natural Sciences of Philadelphia, with 1 plate. 
Long’s Second Expedition to the Rocky Mountains, 2 plates. 
New Harmony Disseminator, book 8 vo, and newspaper form. 
Transylvania Journal of Medicine. 
American Conchology, with 6 S plates. 
Synonomy of Western North American Species of Unio, etc. 
The Plates of Nicholson’s Encyclopedia are fac-similes of those originally published. 
All the other plates have been printed from the copper plates of the original works. 
One copper plate, engraved for Mr. Say, but never published, is added. 
The work also contains a very full Index to all the generic and specific descriptions of 
Mr. Sny, and to the synonyms used in his writings, with the name, date, volume, page, 
plate and figure of the original works containing them. 
Price of the Work, bound in half calf, with plain plates 
Colored ; 
It is hoped that the work will be encouraged not only by the conchologist, but also by 
all those desirous of placing the scattered and generally inaccessible writings of the first 
and greatest American naturalist in a position to afford that assistance to science which 
their merit enables them to do. 
NB. The recipients of the “ Land Shells,” distributed by the Editor in 1856, may obtain 
the continuation of the reprint for $5 50, with plain plates.
