INTRODUCTION TO THE NEW EDITION, 



Since the first publication of my little work on Castration, 

 many editions have been offered to the public and have 

 received such kind reception that I have thought to revise 

 and improve it in many points. In the new (ninth) edition, 

 besides several minor additions, we have rewritten a few 

 entirely and taken advantage of the progress that has been 

 made in the castration of criptorchids and that of the small 

 animals. 



We have also freely quoted from the writings of Professor 

 Cadiot in changing the entire chapter on abdominal and 

 inguinal cryptorchidy, and called upon the experience of some 

 of our American confreres, Dr. T. B. Eodgers, of Wood- 

 bury, N. J., and Prof. E. Ryder, of New York, from whom 

 we have obtained the articles on spaying of swine and 

 caponizing roosters. We take this opportunity to thank them 

 for their kindness in writing those chapters. 



A few new illustrations have also been inserted showing 

 the various steps of castration in ridglings. 



To our publishers, the old house of W. R. Jenkins, we 



tender our thanks for their efforts in allowing us to make the 



work worthy of the reception our friends may give to our 



new edition. 



The Author.
