PREFACE 



This book represents in printed form, notes which have been 

 used for several years in teaching Pharmacy and Materia Medica 

 to Veterinary students. 



Since Veterinarians prepare and dispense a great many of 

 their medicines, pharmacy is quite an important subject to them. 

 It has seemed desirable to include discussions of the different great 

 pharmaceutical groups followed by the actual preparation of one 

 or more examples of each group. The author believes that instruc- 

 tion in this subject can be better carried oh in the laboratory than 

 in the class room. 



The subject of Materia Medica is difficult to present more on 

 account of deciding what to exclude than what to include. It is 

 granted that there are many things in Materia Medica impossible 

 and useless to memorize. On the othCT hand, students should have 

 an opportunity to examine and become more or less familiar with 

 the synon3''ms, origin and physical characteristics of the most used 

 drugs, and laboratory work is believed to be the best means of learn- 

 ing these things. 



The grouping of the drugs for studying Materia Medica is ar- 

 ranged to correspond with the work in Pharmacology but other- 

 wise is purely arbitrary. 



Finally the author desires little claim of originality for the con- 

 tents of the book. He has drawn freely from other most excellent 

 books on the subjects, such as Sollmann, A Text Book of Pharma- 

 cology; Arny, Practice of Pharmacy; Edmunds and Cushny ; Labora- 

 tory Guide in Experimental Pharmacology. He would recommend 

 these books to any who care for more extended information on the 

 subjects.
