(3) cinglica, Alfk. ( = spinigera, 2nd generation) ; (4) roscE, Panz. ;

BOOK NOTICE. 



The Structure of the Fowl. By O. Charnock Bradley, M.D., D.Sc, 

 M.R.C.V.S. The Edinburgh Medical Series. A. & C. Black, 

 London ; pp. xi. -I-153. Price 3s. 6d. 



Among the higher creatures no class possesses organs more peculiar 

 or more specialised than birds, and, on this account, the naturalist who 

 would take an intelligent interest in their habits must pay some pre- 

 liminary attention to their general organisation. Principal Bradley's 

 manual, while intended primarily for the use of students of veterinary 

 science, is an excellent guide for such a purpose. In describing a 

 typical form it serves as an introduction to bird structure and develop- 

 ment in general. It is clearly written, concise, and free from over- 

 loading with non-essential details. The printing is good, and the 

 descriptions are elucidated by many instructive and original figures.
