 the leading ornithological publication of this country. 

 Each number contains about 100 pages of text, a

 tributed by observers throughout the United States 

 and Canada. Recent ornithological literature is re- 

 viewed at length and news itenjs are commented on 

 by the editors. "The Auk" is thus indispensable to 

 those who would be informed of the advance m^de in 

 the study of birds, either in the museum or in the 

 field. Price of current volume, $3.00. Single num- 

 bers, 75 cts.
