7. — A Book of Whales. By F. E. Beddard, M.A., F.R.S. Illustrated. 



8°, $2.00. 



" Mr. Beddard has done well to devote a whole volume to whales. They are worthy 

 of the biographer who has now well grouped and described these creatures. The general 

 reader will not find the volume too technical, nor has the author failed in his attempt to 

 produce a book that shall be acceptable to the zoologist and the naturalist." — N. V. Times.

chology. With special reference to the Invertebrates. By Jacques

 Professor Loeb has brought together in this volume."— Joseph Jastrow, in the Chicago 

 Dial.
