PREFACE. 



The rapid advancement in science has wrought many changes in 

 the principles and practice of medicine ; added new remedies to the 

 re'sonrces of the physician; exploded many old theories, and dissi- 

 pated conntless fancies and prejudices. Well worn paths have 

 been left, new fields traversed, and discoveries made, which aid not 

 only in the cure, but in the prevention of disease. Important 

 lessons have been taught, and the limits of knowledge extended, by 

 trials of endurance which have developed unsuspected latent 

 powers, both in man and animals. Further progress will yet be 

 made, of which speculation is fruitless. 



To place before the reader a faithful exposition of medicine, as 

 it exists at the present time, is the purpose of the author. Ko 

 finished treatise is attempted, replete with scientific technicalities, 

 calculated to confuse and mystify, but in simple, comprehensive 

 language and expression, on these pages are described the promi- 

 nent appearances in disease, and the manner of applying remedies, 

 sustained largely by the results of personal observation. 



This book is submitted with the ardent hope it may be found a 

 source of instruction, and aid in the care of man's true and faithful 

 friend, the Dog.
