PREFACE. 



THE present volume completes a series of sixty Essays 

 dealing with typical examples of the class Mammalia. In 

 this work, as in its predecessors, the subject has throughout 

 been viewed from the combined standpoint of the zoologist 

 and the historian; the photographs are selected from a 

 series of over five hundred negatives taken by the author. 



The opportunity is here taken of thanking the Press for 

 many long and most encouraging notices of previous 

 studies, and the public for their kind reception of former 

 volumes both at home and abroad.
