perience with regard to this disease in any or all of its bearings. 
The malady I have written upon is fearfully destructive ; and if 
such diseases cannot be met with powers capable of wrestling with 
it, I, for one, shall say that it is a stigma upon our art — I shall say, 
that when we are the most wanted, we are of the least use.

Diseased Molar Teeth , giving rise to Symptoms of Ozcena, 
mistaken for those of “ Glanders .” 
I WAS requested a few days since to visit a horse which was 
taken from others on a large common in this neighbourhood, in 
consequence of being supposed to be “ glandered.” My advice 
was sought, for the purpose of giving an opinion with regard to the 
risk of exposing the remainder to his influence. 
I found the animal to be very aged, and in a most emaciated 
and pitiable condition, with a copious greenish and very offensive 
discharge from the left nostril, with slight tumefaction of the gland 
on the same side, there being no appearance of ulceration, but the 
Schneiderian membrane having a leaden dirty hue. Taking all the 
circumstances of the case into consideration, his merely nominal 
value if well, &c., I considered it most advisable to recommend 
his immediate destruction, which was complied with. I ordered 
the head to be sent to my infirmary. 
Being, in the course of the following day, in company with Mr. 
Gloag, of the 11th Hussars, I mentioned to him that I thought I 
had a case of ozsena, and he expressed a wish to be present at the 
examination of the head, a circumstance which I felt pleased to 
avail myself of. 
A longitudinal cut was made with a saw on each side of the septum 
nasi, and a transverse one at aline between the centre of the orbits. 
Another longitudinal cut dividing the maxillary sinuses was made 
just above the fangs of the molar teeth on each side : by this 
means, we had a full opportunity of examining the septum nasi on 
each side, also the turbinated bones, and the frontal and maxillary 
sinuses. On the left side we found an accumulation of pultaceous 
food, covered with thick pus, completely filling the maxillary sinus, 
extending to the turbinated bones, and plugging up all the inter- 
stices formed by their convolutions.
