vi PREFACE. 



The author is especially indebted to Dr. C. E. 

 Sayre, D. V. S., Professor of Dental Pathology in 

 the Chicago Veterinary College, for valuable assist- 

 ance, and to Dr. Anderson, D. V. S., of Louisville, 

 Ky., a graduate of the Chicago Veterinary College, 

 for the valuable chapter on Osteo Porosis. 



Professor Windle, of Earhlam College, prepared 

 most of the drawings from original specimens. 



Sharp & Smith, of Chicago, 111., furnished the 

 cuts of instruments, with the exception of those 

 used in filling teeth; these were kindly furnished 

 by the S. S. White Dental Manufacturing Co., of 

 Philadelphia. The Photo Engravings were made 

 by the Photo Engraving Co., of New York. 



The object of the author in presenting this vol- 

 ume is to bring the subject more clearly before the 

 public, and inculcate in them a true conception of its 

 importance. No branch of veterinary science has 

 been so universally ignored as that pertaining to 

 the management and preservation of the teeth of the 



domestic animals.
