DISEASES OF HORSES IN INDIA, 
parts, near to its junction with the cornea opaca, as much out 
of the range of the pupil as possible, the young parasite made 
his escape with the aqueous humour, and was received upon a 
napkin held under the eye. 
The worm measured an inch and a quarter in length, was 
about the size of a piece of common sewing thread, perfectly 
white, and pointed at both ends. Viewed through a micro¬ 
scope, it resembled a piece of catgut: there were five luminous 
marks distinguishable upon one end of its body, supposed to be 
the head; farther backward there was an irregular luminous 
patch, from which two brilliant lines ran parallel to the other 
extremity. The after-treatment merely consisted of such reme¬ 
dies as were likely to subdue the inflammation :—Venesection, 
brisk cathartics, fomentations, and the exclusion of light from 
the eye. 
Under such treatment the inflammation subsided, and the eye 
became gradually clear; the effused lymph was absorbed, with 
the exception of that upon the spot where the cornea was punc¬ 
tured, which remained, about the size of a sixpence: to re¬ 
move this I had recourse to a variety of applications, but with¬ 
out conferring much benefit. I accordingly discharged him 
from the hospital stable on the 30th of December, the eye being 
in every other respect perfectly sound. 
Still, however, this nebulous patch from time to time gradu¬ 
ally diminished in size ; so much so that on the 10th of Octo¬ 
ber, 1824, it was not more than one half the size it was when 
the horse w^as discharged. 
Case II. 
February 2, 1825. A dun horse, belonging to Captain C- 
troop, was discovered to have a violent attack of inflammation 
of the eye, supposed to have been occasioned by grass, or some 
foreign body, getting into it, as it exhibited no appearance 
whatever of ailment the previous evening. 
Owing to indisposition I w^as prevented from seeing him un¬ 
til the morning of the 5th, when the cornea lucida was parti¬ 
ally obscured from the nebulous effusion, the tunica conjunc¬ 
tiva lining the eye-lids highly inflamed, and the vessels shooting 
into the cornea red and very turgid. 
The animal was very shy of approach on that side ; how^ever, 
it did not require a very close inspection, for even while stand¬ 
ing at some distance from the animal I plainly saw a worm 
floating about in the aqueous humour. 
I operated on him forthwith by puncturing the cornea in the
