The knowledge of these facts may throw some light on the 
mode in which the bacteria penetrate in the case of spon¬ 
taneous Anthrax; it enables us to determine in what part of 
the economy and through what channel the parasites are in¬ 
troduced.— Journ. of the Roy. Mic. Soc. 
EILARIA IN THE EYE.

Society of the Auxiliary Department of the University of Pennsylvania,

Filaria in the Fye of the Horse. 
Hearing, through the kindness of a friend, that there was on 
exhibition, at a stable on Sansom Street, ahorse with a living 
worm in his eye, I at once made search for the curiosity. 
After finding and making a critical examination of the case, 
I was convinced that it was one of more than usual interest. 
At my desire Prof. Joseph Leidy visited the animal with me, 
and as he had never seen such a case before, lie expressed 
himself emphatically concerning its novelty and interesting 
nature. 
As all physicians are more or less interested in horses, I 
have described the case mentioned, as well as two others, both 
of which occurred in this country, have visited some of our 
most prominent veterinary surgeons, and consulted the best 
authorities on helminthology and hippophysiology, so as to 
be able to present a reliable and succinct account of the 
disease in question. 
A heavily built dun horse, twelve years of age, which had 
been raised and worked upon a farm near Rochester, N. Y., 
was led out to the light, and through the partially opaque 
cornea of his left eye could be seen a worm, several inches 
in length. It was white in colour, and without the aid of 
any artificial means could be distinctly seen floating, wrig¬ 
gling, and twisting about in the anterior chamber. The eye 
seemed very much irritated, as the horse continually en¬ 
deavoured to rub it, and the stimulus of light caused profuse 
lachrymation, and what is characteristic in such cases, at 
times only , was the cornea hazy, and the aqueous humour 
cloudy. The horse appeared perfectly healthy, was in 
excellent condition, and did not seem to be particularly 
annoyed by the presence of his unusual guest. The iris was 
of a good colour, the action of the pupil perfect, lens clear, 
and remainder of the eye free from irritation.
