Typhus or Typhoid Affections. 



Ti»e veterinary surgeons of England have hithe* > maiutaiik,d 

 II remarkable silence on the subject of typhoid affections occurring 

 among horses; and so late as the year 1850, Mr. Percivall in- 

 forms the world, through the pages of the • Veterinarian," that in 

 London veiy little is known about such ti.ioease. In view, there- 

 fore, of lighting up the dark spots that exist in our department on 

 this side of the water, we furnish a translation from the French, by 

 Mr. Percivall. The article is a selection from a prize memoir 

 written by a distinguished surgeon. It is preceded, as the reader 

 will perceive, by a review from the pen of the translator, who 

 says: 



" In the ' Collection of Memoirs and Observations on (French) 

 Military Veterinarian Hygiene and Medicine,' which we have ^o 

 lately been engaged in examining, are contained two priiie 

 memoirs — one on Farcy, the other on Typhoid Affections 

 in hcrses.* On the latter of these we would make a few remarks, 

 if it were only for the reaGon of showing what is meant to be un- 

 derstood by such imposing titles. Typhus i*nd typhoid are wordii 

 but rarely heard in our own country in connection with veterinary, 

 or at least with hippiatric, medicine. Our old writers on farriery 

 described fevers in horses as very destructive in their character 

 requiring antiphlogistic treatment: 



"'Typhus Fever. — A disease touching which we (the author) am 

 in possession of but few observations, and one that has been, and 

 still is, in our opinion, mistaken for and confounded with either 

 enteritis or gastro-enteritis — in cases, for example, in which its 

 consequences are of little importance — though, perhaps, with pu- 

 trid fever, when, on the other hand, malignant and exhibiting 

 extraordinary violence, its progress is rapid and its termination 

 fatal. In its most benignant form, typhus fever, indeed, bears sc 

 great a resemblance to pure inflammation of the primary intestinal 

 passages, that it is often difficult, very difficult, even to distinguish 

 them. As for the cause which occasions it to be confounded with 

 putrid fever, it is no matter of astonishment to us, since, in our 

 opinion, one fever possesses, in many respects, so great an analogy
