38f TREPHINE IN DISEASE OF SINUSES OF THE HEAD. 
whitish pus, not very peculiar in consistence, and only 
slightly offensive to the smell; the submaxillary glands of 
the near side were enlarged, but not adhering to the jaw, as is 
frequently the case in the more serious discharges from the 
nostrils ; the Schneiderian membrane looked pale, and inclined 
to a leaden hue; the condition was good. I ordered a nutritious 
diet, and the head to be steamed, by putting the nose in a 
bag containing grass and hot water. Cantharides in com¬ 
bination with vegetable tonics w 7 ere given daily. 
After ten days I found but little or no change to have 
taken place. Sometimes the discharge was profuse, and con¬ 
tained lumps of hardened, cheese-like, and offensive matter; 
at other times it became much less and thinner, presenting 
a blue appearance and having adhesive properties; there was 
also a rattling noise to be heard in the head during respiration. 
I decided to open both the frontal sinuses, and afterwards 
inject some tepid water. A little mucus flowed from the off 
side with the return of the water, but from the near pus 
escaped, both from the opening made and the nostril; the 
smell of which was very offensive. After injecting a sufficient 
quantity of water, a weak solution of alum was thrown in, 
and this was repeated twice daily. The effect on the off side 
vras evident and satisfactory; but on the near, the discharge 
continued, and did not become less offensive. On the 
20th of February I opened the maxillary sinus on the near 
side, and injected into it. The discharge which followed 
proved this cavity to be the principal seat of the disease. It 
was profuse, and exceedingly offensive. The injections were 
continued into both the frontal and maxillary sinuses. The 
off side at that time was nearly free from discharge, and 
therefore was injected only once daily; and by the end of 
February it had entirely ceased, while the matter from the 
near was much altered in character, being more healthy, and 
the disagreeable smell almost gone. I now substituted a 
solution of sulphate of copper for that of alum, and this 
treatment has been continued up to the present time. The 
discharge has now ceased, and I have no doubt the horse 
twill soon return to duty. 
Non-professional readers of the Veterinarian may fancy, 
when perusing the paper by Professor Delwart, that their 
horses have been destroyed unnecessarily, if it should so 
happen that any of them have been destroyed for glanders.
