CORRESPONDENCE. 



The Extra-illustrated Edition of ' Baird, Brewer and Ridgway.' 



Editors of 'The Auk': 



Dear Sirs: — The Academy of Natural Sciences of Philadelphia 

 recently became the possessor of a copy of Baird, Brewer, and Ridgway's 

 ' A History of North American Birds. Land Birds,' which differed from 

 the one already in its library by having in addition to the sixty-four 

 plates of bird-heads, thirty-six plates, each containing a full-length figure.
