PREFACE 



* TO THE 



SEVENTH ElN[GLISH EDITION 



Since the publication of the last edition of this work, 

 a kind of revolution has taken place in Cattle Medicine. 

 Veterinary practitioners had been strangely forgetful of 

 the proper extent of ^their professional duty, and the 

 treatment of the diseases of cattle had, with few excep- 

 tions, (but among which we may justly rank the original 

 author of ** Every Man his own Cattle Doctor,") remain- 

 ed in the hands of the uneducated and the ignorant. It 

 has now, however, begun to be understood that all 

 domesticated animals are the legitimate objects of the 

 veterinarian's care ; and veterinary surgeons of no mean 

 eminence do not think it a degradation to practise on 

 the diseases of cattle, arid sheep, and dogs, and swine. 

 Public lectures on these subjects are at length delivered, 

 in the University of London, and at Edinburgh, and a 

 knowledge of this branch of veterinary medicine has 

 wonderfully increased. 



Under such circumstances the proprietors of this work 

 have endeavoured to discharge their duty to the public. 

 A new edition b^ing required, they have obtained the 

 assistance of an eminent practitioner of both horse and 

 cattle medicine, who, while he has retained all that was 

 useful in the former edition (and there was a great deal 

 that was truly valuable, and particularly with regard to 

 the symptoms of diseases), has endeavoured to keep pace 

 with the progress of the art. The book is in a manner 

 re-written; and the additions on the diseases of swine, 

 now for the first time thrown into a regular and scientific 

 form, in the English language, will be found peculiarly 

 valuable. 



June, 1832.
