SECOND EDITION. BY DELABERE BLAINE. THE CANINE PATHOLOGY is founded on a small work published some years ago, under the title of Cc A Domestic Treatise on the Diseases of Horses and Dogs. In each of the several editions it passed through, I promised that, at a future period, I mould present the public with a more complete and extended work, which should embrace every information connected with the medical treatment of dogs, that a long and successful practice thereon had taught me. By the publication of the Canine Pathology, I have endeavoured to redeem this pledge and when it is considered that the whole path I have travelled over has been hitherto unbeaten, and that no authority existed from whence the smallest assistance couId he gained, the task may be considered as a laborious one, and that some industry and attention have been displayed in its prosecution This Second Edition presents itself with some important additions. The introductory chapter on the Moral Qualities of the Dog has been preceded by an Inquiry into his disputed Origin-a Summary of his Natural History-and an Account of the principal Varieties into which he is branched out all of which will, I hope, prove not uninteresting or unacceptable to the lovers of the animal in question. Every member of society owes, both to his friends and to the public, eithcr a direct consistency of conduct, or somc statement of the reasons that have occasioned a departure therefrom. Under the guidance of this sentiment, in the former edition, I entered into a detailed account of circumstances which for the purpose of..introducing more important matter I have now cendensed into the following apologetical facts - I As it is generally understood that I was regularly educatdd to he practice of human medicine, so some surprise and inquiry have been excited relative to the motives that influenced my departure from the regular track of my profession, to stoop, as it is considered, to the medical treatment of such inferior branches of the creation as Horses and Dogs. In answer to these inquiries, I have to alledge, that my first motives mere, an inherent and powerful attachment to brute animals in general, which early prompted me to study their habits, and take a warm interest in their welfare. This predilection strengthening with my years, engaged me, during the prosecution of my medical stndies, to pay particular attention to comparative anatomy, which a residence with the ingenious Dr. HAIGHTON tended to promote. A knowledge that such were my predilections, gained me the notice of the patrons of the Veterinary College and I was, by them, ffered the appointment of Demonstrator and As- sistant Anatomical Teacher to the pupils of that Establishment. Here my attention was directed to the diseases of animals likewise and, on my removal, from the College, I gave a course of public lectures on the anatomy and physiology of the horse. I continued, for a few years afterwards, to endeavour to extend the knowledge of the veterinary art, - at that time but little known, aid its importance but little appreciated and I may enurnerate, among the additions I made to the general stock, an improved method of treatment of foundered Feet in Horses, and a successful remedy for the Distemper in Dogs...
