PREFACE. 



The writer wishes to acknowledge his indebtedness to 

 the works of Brunton, Wood, Hare, Edes, Ringer, Bar- 

 tholow, White and Mann, in human medicine ; and to those 

 of the following veterinary writers : Finlay Dun, Fried- 

 berger and Frohner, Ellenberger, Koch, Cagny, Miiller ; 

 and to thft leading veterinary periodicals. 



The matter on "properties," ^description," and, in 

 many cases, "derivation," is according to the U. S. Phar- 

 macopoeia, while the important preparations of both the 

 U. S. and British Pharmacopoeias are included. The classi- 

 fication and arrangement of drugs employed in this book 

 are modifications of those adopted by W. Hale White in his 

 excellent treatise on Materia Medica, Pharmacology and 

 Therapeutics.
