work, together with certain chapters considered of minor interest^ 

 have been omitted ; forty-nine new articles have been added, and the 

 number of illustrations has been nearly doubled. 



To Professor Cadiot, who has extended to me every assistance in 

 his power, I hereby express my liveliest gratitude ; while for the un- 

 failing patience and friendly sympathy with which Professor McQueen, 

 of the Royal Veterinary College, London, has carried through the 

 task of reading the proof-sheets of the present work I desire to tend^ 

 him my sincerest thanks.
