This book is intended for a practical text on "Veterinary Materia 

 Medica, Pharmacology and Therapeutics. The author realizes that 

 the only object of studying pharmacology is the use of drugs in treat- 

 ing disease, yet, in order to prescribe a drug intelligently it is nec- 

 essary to have more than a general idea of its action. The greater 

 emphasis is placed upon pharmacology because the author believes 

 that the only place to study Materia Medica is in the laboratory and 

 Therapeutics can best be studied in medicine and the clinics. 



There are numerous ways in which remedies may be grouped 

 and none is perfect although it seems that a therapeutic grouping 

 has many advantages since it allows a better correlation between 

 the action and the uses of the different agents. Consequently the 

 plan has been to discuss the different groups in a general way and 

 then follow with a detailed description of the individual drugs. 



The prescriptions are intended only to be representative and to 

 ilhistrate the ways in which medicines may be prescribed, although 

 many of them have been tried and are in almost daily use by the 

 author. 



The author claims little if any originality in the material in- 

 cluded. He has drawn freely from the current literature and stand- 

 ard books on the subject. He has not considered it wise to include 

 a bibliography in a book of this kind. Yet he would especially 

 desire to mention such books as those of Cushny, Sollmann,^ Bastedo, 

 Dixon, Hoare and Frohner on pharmacology and therapeutics ; those 

 of Law and Hutyra and Marek on medicine and Arny on pharmacy. 

 In conclusion I desire to express my appreciation to Dr. C. P. Fitch 

 for the most excellent chapter on Bacterius, Serums, Vaccines and 

 antitoxins, and to Prof. P. A. Fish for the use of several tracings.
