NASAL GLEET. 
affected side of the head. For this purpose I had made a tre- 
phine of unusually small size, which would not include more than 
a circle of a quarter of an inch in diameter. With this I sawed 
out a piece of the near frontal bone. The removal of it was fol- 
lowed by a rush of air through the sinus. The animal, indeed, 
respired through the aperture much in the same manner as happens 
in tracheotomy. Clean tepid water was injected, but flowed out 
through the external nares as freely as it was thrown in, and as 
free from stain or taint, save that the first injection or two proved 
bloody. Clean dry feathers introduced and moved about within the 
sinus failed to detect any lodgment of matter. I had a leathern 
cap appended to the brow-band of the head-collar, to cover the 
aperture made by the trephine ; I soon, however, found that the 
simplest and best means of closure was a phial cork, to fit the hole. 
The morning after the operation, foetor was as strongly and 
offensively perceptible as ever from the nostril ; I, therefore, sub- 
stituted an injection of the solution of chloride of lime in place of 
plain water. Before I did so, however, I once more tested the 
sinus by the introduction of feathers, but with no other result than 
before. 
Finding the chloride of lime of no service I once more resorted to 
the creasote injection. This brought back the discharge, and in a 
purulent form too, as abundantly as ever; and it would now appear 
as if some lodgment of it took place, for the injections occasionally 
brought lumps or masses of muco-purulent matter away with them. 
I continued these injections morning and evening for eight days, 
and found, by them, that I had in all its copiousness and virulence 
completely re-established the nasal flux, and, with it, had caused 
fresh swelling of the submaxillary glands, the foetor still con- 
tinuing the same. It was again evident that the creasote injec- 
tions, in their primary or immediate effects, were to appearances 
harmful, and, therefore, they were aga,in discontinued : the only 
question concerning their operation being, whether or not, in their 
secondary or remote effects, after the irritation they had caused 
afresh had subsided, they did not prove beneficial. 
Although, from the moment I had observed the tendency that 
existed in the opening made by the trephine to granulate and 
heal up, I had kept a phial cork pushed into it, yet were Nature’s 
efforts so great and irresistible to close up the artificial aper- 
ture, that, although no granulations could sprout from around the 
margin of the aperture, they actually grew from within the 
cavity of the sinus in such force as quickly to form a partition 
abutting upon the end of the cork, and thus, in spite of cork or 
plug, (lid Nature accomplish her work and shut up the sinus. 
With an iron probe I broke down this partition, and thus sue-
