This work is based largely upon the article " Mammalia," together with forty 

 shorter articles, written by the senior of the two authors for the ninth edition of the 

 " Encyclopaedia Britannica." 



The best thanks of the authors are due to Dr. G. E. Dobson, F.R.S., Mr. Old- 

 field Thomas, and Dr. St. G. Mivart, F.R.S., for freely permitting the incorporation 

 of their own work in the present volume. 



Mr. Lydekker undertook the task of arranging the various articles in their 

 proper sequence, selecting from these such portions as seemed suitable, filling up 

 the gaps, and adding new matter where necessary, a large amount of this new 

 matter treating of the extinct forms, and also of the group Artiodactyla. from 

 the Preface.
