average student. But the.book is no mere analytical key to the 
animal kingdom. ‘The anatomical character of each type, class 
and order are briefly but clearly presented. It is a hand-book

facts and arguments, but unfortunately is scarcely comprehensible 
save by those who know nearly as much of the history and phil- 
ology of the ancient races as does the author.
