CANCEROUS TUMOUR IN A DOG. 
Feb. 17th.—The horse eats well, and has not had another 
attack. Keep him quiet, and allow plenty of mashes, &c. 
20th.—He appears in the same state as at my last visit. I 
had him taken out again, and walked once round the yard, 
when he was again attacked ; and although the tube was in 
the trachea, the spasms continued for half an hour, and the 
horse seemed to be dying; he, however, soon recovered. I 
now determined to trephine the frontal sinuses, and likewise 
passed a tube up each nostril, but nothing abnormal could be 
detected. Again blister the throat and face, and keep the 
animal quiet. 
25th.—The pulse is natural, and the appetite good. I 
ordered him to be turned out for a few hours after I left; 
and on the 26th he was turned out again, but a short time 
after he was found dead in the field, the tube having fallen 
out of the trachea. 
28th.— Post-mortem examination .—On opening the trachea 
as far up as the larynx, I found the whole of the mucous 
membrane highl} 7 inflamed. The inflammation extended to 
the opening of the oesophagus, the whole of the fauces, and 
along the nasal cavities, where I found one or two ulcers. 
On opening the frontal sinuses, there was an abscess, about 
the size of a goose’s egg, underneath the mucous membrane, 
and partially embedded in the ethmoidal cells. On punctur¬ 
ing it, a muco-purulent fluid, foetid, and of a greenish hue, 
escaped. On opening the lachrymal sinus, I found it highly 
inflamed, but there was no abscess. The whole of the viscera 
of the chest and abdomen were healthy, as also was the 
brain. 
1 do not remember having seen recorded a case similar to 
this, as following influenza or any other disease of the head or 
air-passages; and such, therefore, in my opinion, ought to be 
given publicity to through our valuable journal, so that we 
may be able to ascertain the seat of disease, and thus treat 
such cases successfully. Although I had trephined the 
frontal sinuses, 1 happened to be a little below the abscess, 
and consequently considered them not to be implicated.
