AUTHOR'S PREFACE. 



Within the past decades several works discussing Veter- 

 inary Obstetrics have been issued. I refer to the text-books 

 of Baumeister-Rueff, Harms, Lanzillotti-Buoiisanti, St. Cyr 

 and Violet, Sjostedt, Franck-Goring, Fleming and Deneubourg, 

 who treated the subject in detail. 



The fact that I had to deal exclusively with bovine obstet- 

 rics, induced me to accept Professors Dr. Bayer and Frokner's 

 suggestion to write this work. 



A specialized treatise on bovine obstetrics demands a 

 rather broad presentation, as it is most frequently met with in 

 obstetrical therapy. Taking this fact into consideration, 

 certain sections were treated in detail, — for instance, abortion, 

 torsion of the uterus, dystokia from malpositions and partu- 

 rient paresis. Embryotomy also was fully dealt with, since 

 many years of experience have shown me the important rele it 

 plays in a bovine obstetrical practice, and an exhibition of the 

 various methods, especially in regard to the beginner, are 

 desirable. The supplement, " Auxilliaries in the Study of 

 Mechanical Obstetrics," reviews the manner by which the 

 students, in comparatively short time, may acquire some 

 dexterity in reposition and embryotomy.
