PREFACE TO THE SEVENTH EDITION. 



It is a source of much gratification to the Author that a new 

 edition of this (the seventh) and the companion work, "The 

 Principles and Practice of Veterinary Surgery" (the eighth) 

 have again been called for. Both works have been carefully 

 revised and brought down to date, and while in the latter the 

 changes required have not been so great, the advance in the 

 science of Veterinary Medicine has been so important as to 

 necessitate considerable alterations in portions of the text. It 

 has been the Author's endeavour to watch closely, both by 

 means of original research and by the study of the work of 

 the most eminent Pathologists, all the developments which 

 have taken place in that science, and professional men and 

 students will find the results incorporated in this work. 



The diseases of Domesticated Animals, and their preservation 

 in a state of health, have long since become important factors 

 in connection with the vital question of the food supply of the 

 country, and the Members of the Veterinary Profession must 

 continue to give their utmost attention to the advancement of 

 Veterinary Science, as more than ever this question has become 

 of national importance, especially since the depression in 

 Agriculture, and the substitution therefor to a great extent 

 of the rearing and feeding of Cattle, and also their importation 

 in such large numbers from Canada, the United States, and 

 other countries.
