PREFACE. 
1 HIS Manual is published with the same useful view 
which has been submitted in the Preface to the * Analysis 
of the Natural Classification of Mammalia/ 
The text is translated from Cuvier, arranged in a ta- 
bular form, illustrated by figures, and explained by notes 
comprehending the additional information which I have 
acquired during a patient study of the subject^ preparatory 
to "second travel in Africa.
