VERBAL COMMUNICATIONS. 



Dr. Cogswell, Secretary and Librarian of the Northern 

 Academy of Arts and Sciences at Hanover, New Hamp- 

 shire, then briefly addressed the Society in reference to the 

 origin and design of that Institution, and on its behalf 

 solicited several volumes of the Journal of the Academy, 

 which it was desirous of possessing in order to complete 

 its series of the same. 



The Chairman announced that Mr. John James Audubon 

 and Mr. Edward Harris, accompanied by an artist, left this 

 city yesterday morning on their route to St. Louis, and 

 thence to the sources of the Yellow Stone Eiver and the 

 Eocky Mountains. The object of this expedition is the 

 discovery of new species of Birds and Quadrupeds for the 

 works of Mr. Audubon, and especially for his Mammalogy 

 of North America, now in course of publication. The 

 expedition is expected to return in October, and promises 

 important additions to every department of natural science. 



The Chairman also called the attention of the Society 

 to the first number of Mr. Audubon's "Quadrupeds," which 

 is placed in the Hall for inspection, and for the subscription 

 of such members and others as may desire to possess this 

 truly splendid and invaluable work.
