ON WORM IN THE EYE OF THE HORSE.

/ 
However, as I have given you my opinion candidly, I trust, if 
I am wrong, some of your valuable correspondents will put me 
right. I will now, if you please, relate a case or two which oc¬ 
curred in my practice, because they are not very common. 
CASE I. 
In the month of March 1830, my attention was called to a 
brown country-bred horse, as I was walking through the lines 
inspecting the troop horses in stable. On examining the horse’s 
eye I found considerable opacity of the cornea; and I fancied I 
could see a worm floating about the anterior chamber; but not 
being certain, I had the horse removed to the hospital, and bled 
8 pounds, and the eye constantly kept wet with diluted liq. plum, 
acet. On the morrow morning the opacity was considerably 
removed, and I had a full view of the enemy. I did not hesitate 
a moment then, but at once proceeded to extract the worm, which 
I did with a common abscess lancet, about the middle size, first 
guarding it with a skein of tow, so that about three-eighths of 
an inch of the blade projected. I simply had the horse secured 
with a twitch, preferring to perform the operation on the horse 
standing, though I have heard of some veterinarians casting the 
animal. I then waited for a favourable opportunity of the eye¬ 
lids separating for puncturing the cornea, this being sometimes 
very tedious, so much inflammation and consequent irritation 
going on in the eye and its appendages. After a little patience 
I made a puncture nearly in the middle of the cornea, when out 
came the aqueous humour, and with it the worm on to the back 
of my left hand. I deposited the little fellow in a bottle for fu¬ 
ture examination. I then ordered the horse aloes 3v, tereb. vul. jij, 
and continued the lotion for about a week : the medicine operated 
well, but the eye did not get clear so fast as I imagined it would. 
I therefore changed the lotion for a weak solution of sulph. zinc, 
and gave an alterative twice a-week for three weeks longer, when 
the horse was discharged, free from any opacity, with the excep¬ 
tion of a small hair line occasioned by the puncture : but in the 
course of three months this entirely disappeared. 
I examined the worm as well as I could with the naked eye, 
not having an opportunity of procuring a glass. The worm was 
nearly an inch and three-eighths in length, with a black speck 
at both ends, but which was head or tail I really cannot tell. 
Its size was about that of the middling-sized sewing cotton. 
CASE II. 
In the month of May 1830, one of the farriers reported a ches- 
nut horse as having worm in the eye. I had the horse to the
