" A work by a master in the science who understands the signifionnce 

 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 text-hook of the historical phase of palieontology io 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 his library complete." — The Quarterly Journal of Science. 



" The Professor of Natural History in the University of St. Andrews 

 has, by his previous works on zoSlogy and palteontology, 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 history will receive the present volume. It is, as its second title 

 expresses itj a comprehensive outline of the principles and leading facts of ' 

 palasontoiogieal science. Numerous woodcut illustrations very delicately 

 executed, a copious glossarv, nnd an admirable index, add much to the 

 value of this volume?*' — Athenmiim.
