NASAL GLEET — THE TREPHINE — ANEURISM OF 
THE AORTA. 
By Mr. Harry Daws, V.S., London. 
Mr. MALLALUE’s bay gelding, four years old, had had a dis- 
charge of mucous purulent matter from the right nostril for six 
weeks, accompanied by an enlargement of the submaxillary glands 
on the same side. He presented a very suspicious appearance, 
and was considered by many to be glandered. Had it not been for 
this complaint he would have been valued at 140 guineas. 
His throat and the off- side of his head had been repeatedly blis- 
tered, without the least benefit. He was this day, April 1, 1S39, 
subjected to the operation of the trephine. A circular aperture, 
three-fourths of an inch in diameter, was made into the frontal 
sinus, between the orbit and the nasal suture; and a weak solution 
of the sulphate of zinc was injected into the sinus. The injection 
was daily repeated. 
In ten days it became more viscid and paler in colour, and the 
injection was then suspended. The discharge soon assumed a pu- 
rulent, and then a muco-purulent, and a mucous, and, finally, a 
serous character, after which it disappeared altogether. The wound 
skinned over readily, and the enlarged gland had entirely disap- 
peared on May the 7th. 
1839, April 30.— I was yesterday called upon to attend a horse 
more than twenty years old, and exhibiting the following symp- 
toms. Profuse perspiration, literally as wet as if he had been 
dragged through a pond — a disposition to squat upon his haunches 
— protruding his head as if choaked — respiration natural — pulse 
about 40, but intermittent, and accompanied by a peculiar grating 
or rasping sensation. The submaxillary artery not at all enlarged 
in character. 
I confess that I was not a little puzzled as to the precise nature 
of the disease; but the more I reflected on it, the more I was con- 
vinced that there was some morbid affection, and, probably, altered 
structure of the heart or large bloodvessels. I removed my pa- 
tient from the confined situation in which I found him to an open 
and airy place — allowed him to drink freely of cold water, and gave 
him an ounce each of tincture of opium and the spirit of nitrous 
ether. He soon became considerably relieved, and, in the even- 
ing, my assistant administered four drachms of Barbadoes aloes in 
solution. 
July . — He has not had any return of the violent symptoms 
described, but his pulse still possesses that peculiar characteristic 
better felt than described.
