PREFACE TO THE FIRESIDE EDITION vii 



In view of the constant, and often exasperating, changes that 

 are being made in the Latin names of animals, I regard it as useless 

 and unnecessary to attempt to keep up with them; and therefore 

 I have made no changes whatever in the names that were originally 

 chosen with great care in the first composition of this work. 



Both the author and the publishers thank the public and the 

 press most gratefully for the signal marks of approval with which 

 this work has been received. It is that approval which has made 

 this four-volume edition seem worth while. The author, by numer- 

 ous amplifications and by substantial additions in various direc- 

 tions, gladly avails himself of this opportunity to bring the work 

 down to date, in all particulars save a few that will not seriously 

 affect the progress either of the general reader or of the student.
