'' A work by a master in the science who understands the sitrnificance 

 of every phenomenon which he records, and knows how to make it reveal 

 its lessons. As regards its value there can scarcely exist two opinions. As 

 a lext-book of the historical phase of pahvontology iu will be indispensable 

 to students, whether specially pursuing geology or biology ; and without 

 it no man who aspires even to an outline knowledge of natural science can 

 deem liis library complete." 2'he Quarterly Journal of Science. 



"The Professor of Natural Ilistory in the Tniversity of St. Andrews 

 has, by liis previous works on zoology and palawntology, so fully estab- 

 lished his claim to be an exact thinker and a close reasoner, that scarcely 

 any recommendation of ours can add to the interest with which all students 

 in natural liistory will receive the present volume. It is, as its second title 

 expresses itj a comprehensive outhne of the principles and leading facts of 

 palaiontologieal science. Numerous woodcut illustrations very delicately 

 executed, a copious glossary, and an admirable index, add much to the 

 Vflue of this volume." AthencBum.
