404 Miscellanies. 



3. Association of American Geologists and Naturalists. — This body 

 holds its sixth annual session in the city of Washington, commencing 

 on Wednesday the 8th* of May, at 10 A. M. The central position of 

 the place of meeting, with the growing importance of the Association, 

 it is believed will secure a full and interesting meeting ; while the 

 efforts made by the standing committee will conspire to the same end. 



Our miscellany and notices of new books are necessarily abridged in 

 the present number, owing to the pressure of original and longer com- 

 munications. 



We are sensible that a fuller review of foreign science is expected 

 at our hands, and that the majority of our readers prefer more con- 

 densed abstracts of foreign matter and miscellaneous communications, 

 and it will be our endeavor hereafter, to give more fullness to this 

 department of the Journal. 



Among the new books which we have received, and of which notices 

 are deferred to a future number, are
