The rapid advancement in science has wrought many changes in the principles and practice of medicine; added new remedies to the resources of the physician; exploded many old theories, and dissipated countless 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. No 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 prominent 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.
