VI PREFACE TO FIRST EDITION. - 



these microscopic views and drawings, by my colleague Dr. 

 Young, and Mv. Yauglian, one of my own students. 



I venture to express a hope that this work will be found 

 acceptable, both to Practitioners and Students of Veterinary 

 Science, for Avhom it has been specially prepared. 



It will be seen by the professional reader that it contains 

 much matter relating to human pathology, necessarily intro- 

 duced for the purpose of denoting the similarity, or identity, 

 of morbid actions in man and the lower animals ; and I have 

 not hesitated to make quotations from the works of various 

 pathologists, whose names are duly acknowledged. 



I have to express my thanks to Professor Bennett, Dr. 

 Eedfern, Dr. Chance (the translator of Yirchow), Dr. Arnott, 

 and Professor Simonds, for the use of their plates; to Mr. 

 Broad, of Bath, for many valuable suggestions on the Diseases 

 of the Feet ; and to Mr. Stevenson Smith, of Edinburgh, for his 

 careful revision of the section on Diseases of the Skin.
