X FREFACE. 



Thomson, M.D., E.E.S., and to Messrs. Longmans & Co., 

 Messrs. Cassell & Co., and Messrs. Kegan Panl & Co., for 

 the use of various electros. 



Dr. Murie, F.L.S., has had charge of many of the wood- 

 cuts, certain of which — representing ligaments, viscera, 

 and salivary glands — have been drawn from his dissections 

 and under his supervision. 



I have to thank Mr. Alban Doran, who has made careful 

 dissections of the internal ear and portions of the generative 

 organs, and also Mr. P. Percival Whitcomb and my son 

 Mr. Frederick St. G. Mivart, for more or less assistance. 

 To Professor Cope I am much indebted for very kindly 

 sending me proofs of unpublished plates of American 

 fossils described and named by him. 



I have also to express my obligation to Mr. Wm. Pearson 

 (of the College of Surgeons) for making some excellent 

 dissections, from which certain of the illustrations are 

 taken. Original drawings have also been made from 

 specimens preserved in the museum of the Eoyal College 

 of Surgeons and in the British Museum. The di-awings 

 have (with the exception of six figiu'cs of fossil remains) 

 been executed by Mr. C. Berjeau and engraved by Mr. 

 Ferrier. I feel bound to express my sense of the skill 

 evinced in theii* execution.
