NOTICES OF NEW BOOKS, 



Life and Rock : a Collection of Zoological and Geological Essays. 

 By R. Lydekker. 8vo, pp. 220. With illustrations. 

 London : Witherby & Co. 1894. 



Of the twenty-one chapters contained in this volume the 

 majority are devoted to zoology, and especially to its palseonto- 

 logical branch, while a smaller number relate to geology proper. 

 While some of the former treat of the natural history of 

 particular groups or species of animals, others are more 

 especially devoted to a consideration of some of the many 

 interesting problems connected with evolution, development, and 

 mutual relationships of animals, which at the present day are 

 attracting so much attention. 



To enable the reader to form some idea of the nature and

 Whalebone Whales; Ruminants and their Distribution; The 

 Giraffe ; Lemurs ; Armadillos and Aard-varks ; the Oldest 

 Mammals; Crocodiles and Alligators; The Oldest Fishes and 

 their Fins; Living Fossils; The Extinction of Animals; Pro- 

 tective Resemblance in Animals ; Sea Urchins ; Nummulites 

 and Mountains ; A Lump of Chalk and its Lessons ; and A Flake 

 of Flint and its History." 



On all of these subjects Mr. Lydekker has information to 

 impart ; not much that is new perhaps, but yet a great deal in a 

 few words which have the merit of conveying to the reader just 

 what he wants to know, and what he has possibly looked for
