VI PREFACE. 



The engraving of these has occupied considerably longer time 

 than was at first anticipated, but the important character of 

 the added matter fully compensates for any delay, and must be 

 held as largely contributing to whatever degree of success the 

 book may eventually attain. To the pains Mr. Wheatley has 

 taken in superintending the preparation of both shoes and 

 illustrations, the enthusiasm he has exhibited in the work now 

 completed, and the personal kindness he has at all times 

 shown, the writer cordially testifies. 



Messrs. Schonefeld of Dresden have kindly permitted the 

 use of the majority of the wood-cuts, and Messrs. Phipson & 

 Warden, iron merchants, etc., Birmingham, have accorded a 

 similar privilege in respect of the illustrations marked with 

 an asterisk. 



To Professor M'Queen, of the Boyal Veterinary College, 

 London, who rendered such valued service during the publi- 

 cation of the work on Veterinary Surgery, the writer has once 

 more the sincere pleasure of tendering his thanks, and of 

 gratefully acknowledging how much he owes to that gentle- 

 man's kindly encouragement and assistance in revising proof- 

 sheets during the two years devoted to this later task.
