PIG TYPHOID. 
By J. Arnold, M.R.C.V.S., Thrapston. 
I was pleased to observe your remarks on pig typhoid in 
the editorial of last month’s Veterinarian. 
Our market for the last four or five years has been a 
perfect hotbed of pig typhoid fever in its most virulent and 
destructive form. 
I have on several occasions known a litter of pigs ex¬ 
hibited and sold in the market whilst suffering severely 
from the disease, and in the course of a few days every one 
of them had died ; little or no notice being taken of the 
matter. Two or three cases have, however, been the sub¬ 
ject of County Court actions, but in each of them the plaintiff 
has failed, not being able to prove guilty knowledge on the 
part of the vendor at the time of sale. 
I am fully assured that pig typhoid, at least in this neigh¬ 
bourhood, is a far more serious ailment than it is generally 
thought to be, and hence these facts may not be unworthy 
of notice. 
CASE OF NAVICULAR DISEASE OF BOTH THE 
FORE AND HIND FEET. 
Communicated by F. Blakeway, M.R.C.V.S., Stourbridge. 
A grey gelding, and a capital hunter, the property of a 
gentleman in this neighbourhood, became lame in the near 
fore foot after the hunting season of 1859. The lameness 
was believed to be due to navicular disease. The operation of 
neurotomy was ultimately had recourse to. The horse 
subsequently did his work as well as ever, and was ridden 
to hounds regularly till the end of the year 1861, when he 
went lame of the off fore foot. From this date he also 
showed very peculiar action behind, and was at times lame 
of both hind limbs without any apparent cause. 
In the year 1862, from the groom’s indiscreet use of 
physic, superpurgation was brought on, which caused the 
animal’s death. On a post-mortem examination being made 
the horse was found to have navicular disease in all four 
feet. It is worthy of note that this horse had always “ extra¬ 
vagant” action behind, but was a remarkably quick and good 
jumper.
