110 DADD’S VETERINARY MEDICINE AND SURGERY. 
TypHus or TYPHOID AFFECTIONS. 
Toe veterinary surgeons of England have hithes » maintaia.d 
a remarkable silence on the subject of typhoid affect.ons occurring 
among horses; and so late as the year 1550, Mr. PERCIVALL in- 
forms the world, through the pages of the ‘ Veterinarian,” that in 
London very little is known about such aicsease. In view, there- 
fore, of lighting up the dark spots that exist in our department on 
this side of the water, we furnish a translution from the French, by 
Mr. Percivauu. The article is a selectiou from a prize memoir 
written by a distinguished surgeon. It is preceded, as the readec 
will perceive, by a review from the pen of the translator, who 
says: 
“Tn the ‘Collection of Memoirs and Observations on (French) 
Military Veterinarian Hygiene and Medicine,’ which we have te 
lately been engaged in examining, are contained two prize 
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 reason of showing what is meant to be un- 
derstood by sucl: imposing titles. Typhus una typhoid are words 
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) are 
in possession of but few observations, and one that has been, and 
still is, in our opinion, mistaken for and confounded with either 
enteritis cr 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 analegy

‘Tee Veterinarian,” vol. xxii, p. 462.
