PLEURO-PNEUMONIC EPIZOOTIC AMONG CATTLE. 493 
on the side affected is a little enlarged, and there is also a dis- 
charge from the eye. I inserted a seton along the gland, and 
blistered between the jaws, and also on the face. He got con- 
siderably better. I examined the teeth, but found nothing 
wrong. The discharge is very little, except when he is put to 
work, when it greatly increases, is of a white curdy appearance, 
and comes away in clots, with a fetid smell. 
The other horse exhibits a very similar appearance, which 
leads me to think that there is an accumulation of matter in the 
sinuses. 
I was thinking of opening one of the sinuses ; but if you would 
prescribe any other treatment, or give me your opinion on the 
cases, you would greatly oblige me.

wash out the nostril daily, or twice a-day, with tepid water for a 
few days, and afterwards to inject a weak solution of the sul-

Cattle, in anticipation, along with others of your correspondents, 
that the subject might engage that attention from the profession 
which its importance merits : with the exception, however, of a 
few remarks from Mr. J. M. Hales and another practitioner or two, 
our hopes have not been realized. 
Observing in the present month’s Veterinarian an editor- 
ial request for information on this head, also one from Mr. Relph, 
whose communications on cattle I have uniformly much pleasure 
in perusing, I shall offer no further apology for troubling you, as, 
since leaving the Edinburgh Veterinary College last spring, this 
affection has formed the bulk of my cattle practice, and I have 
at the present time a number of these cases under treatment. 
I have not been able to ascertain whether this disease pre-
