PREFACE 



Feeling that the students and practitioners of Veterinary 

 Medicine have long been in need of a condensed work on 

 Theory and Practice of Equine Pathology, the author has put 

 forth his energy in their behalf. 



He hopes that his efforts will not be misunderstood, as a 

 small work like this cannot and is not intended to be as com- 

 plete as larger ones. If this will be a help to students in get- 

 ting their degrees and in passing the State Boards, and to the 

 busy practitioner for quick reference, then his efforts have not 

 been misplaced. 



The author has used as concise and as plain language as 

 possible, often at the expense of grammatical precision. 



Some of the prescriptions in the Appendix are those I 

 have used in practice, while others are among some selected 

 from divers places, but whose authorship is unknown to me. 



The following are the writers freely referred to : Professors 

 Jas. L. Kobertson, A. F. Liaiitard, W. "Williams, F. Dunn, 

 Wm, Robertson, Friedberger and Frohner, Jas. Law, A. Smith, 

 Wm. Osier, Wm. H. Thomson, Loomis, Pepper, Flint, and 

 others. I am indebted to Professor Eoscoe E. Bell for his 

 valuable assistance in correcting proof, and to my brother, F. E. 

 Hanson, D.V.S., who has kindly assisted me in preparing the 

 Index. 



In conclusion, I would ask and highly appreciate any 

 suggestions Avhich the readers may feel disposed to make for 

 the improvement of the work. 



THE AUTHOR. 



New York City, January, 1899.
