WORMS IN THE EYES OF OXEN. 
79 
Whether the worm be already hatched or the germ only be 
present, the treatment is all the same : in one case it arrests the 
formation of the worm ; in the other it destroys it. The remedy 
consists in a mixture of equal parts of tincture of aloes and 
xvater (better if it be distilled). The head is to be so inclined 
that the eye is directed upwards, the lids are to be distracted, 
and half-a-tea-spoonful of this mixture poured over the surface 
of the globe of the eye; immediately this is done, the animal 
closes the eyelids and works the eye about on every side. ' /The 
circumference of the lids should also be wetted with this lo¬ 
tion. The same dressing requires repetition thrice a day, and 
for three or four successive days, or until such time as the worm 
can no longer be perceived to move. But it seldom survives 
this period. In some cases from the very first day the worm 
sinks motionless into the bottom of the chamber, and there re¬ 
mains along with its envelope or germ ; after which both become 
absorbed, and the eye, as the absorption goes on, recovers its 
former condition. The recovery is more speedy when the in¬ 
flammation of the surrounding parts, as well as the eye, occa¬ 
sioned by the worm and the injections, is checked by appro¬ 
priate means. A decoction of mallows with a few drops of ace¬ 
tate of lead I find veiy useful. Unless the disorder be advanced 
this treatment will prove successful; when the worm has made 
ravages in the eye, all measures are unavailing : the pupil be¬ 
comes dilated; the chrystalline acquires a yellow hue, and af¬ 
terwards manifests opacity, which increases until the sight is 
quite gone. 
Remarks on the foregoing Paper^ hy M. Desmarets. 
Long since, our attention has been directed to the presence 
of worm within the eye of the horse. Hopkinson has mentioned 
(in the Second Volume of the Transactions of the Philosophical 
Society of Philadelphia) one from two to three inches long, of 
the size of a thread : * the same work also contains an account 
of a living serpent being discovered in the horse^s eye, which 
appears to be nothing more than the same production.f 
It has not yet been definitively settled to what species this 
worm belongs. M. Budolphi seems inclined to think that it 
comes under the Filaria Papillosa; and what to me appears to 
strengthen this opinion is the fact of the filaria papillosa, which
