A BOOK OF WHALES 



By F. E. BEDDARD, MA., ER.S. 



With 40 Illustrations by Sidney Berridge. 6s. net 



A distinct gap in the literature relating to whales has been filled by this 

 book, for it provides in a comparatively small compass a general account of 

 this group of mammals. The aim has been to produce a solid book tempered 

 by anecdote. It is not a monograph of the Cetacea ; but on the other hand, 

 at least, the main facts of structure and mode of life of these interesting and 

 remarkable creatures are given.
