‘“*A work by a master in the science who understands the significance of 
every phenomenon which he records, and knows how to make it reveal its les- 
sons. As regards its value there can scarcely exist two opinions. As a text- 
book of the historical phase of paleontology it will be indispensable to students, 
whether specially pursuing geology or biology; and without it no man who as- 
pires even to an outline knowledge of natural science can deem his library com- 
plete.” 
Atheneum. 
‘The Professor of Natural History in the University of St. Andrews has, by 
his previous works on zodlogy and paleontology, so fully established 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 na-ural history will 
receive the present volume. It is, as its second title expresses it, a compre- 
hensive outline of the principles and leading facts of palzontological science. 
Numerous woodcut illustrations very delicately executed, a copions glossary, 
and an admirable index, add much to the value of this volume.”
