WORM IN THE EYE OF THE HORSE.

mencement of March. This is, a fact which I have for a length 
of time noticed and recorded, and which has inclined me to 
consider the appearances of the worm in the eye as connected 
with a particular season of the year. 
I have generally observed, that the heavier the rains have 
been during the periodical rainy season, and particularly to¬ 
wards their close, the more numerous have cases of worm in the 
eye been during the subsequent cold season. In such seasons 
in Tirhoot, the fogs are always more heavy and frequent than 
when the rainy season has been moderate. 
"" At the commencement of the present cold season, the fogs 
in Tirhoot were very frequent and heavy, and' more cases of 
worm in the eye have occurred this season than for several years 
past. The rains were unusually heavy last year, and continued 
to a later period than common: the whole country in that dis¬ 
trict was inundated by the rains. The country is low, and 
there are dispersed through the district a great many jcc/s or 
low spots containing water during the whole year. I conceive 
that it is chiefly owing to the low situation and damp climate of 
Tirhoot, that the worm in the eye, and the disease called Kum- 
ree, or weakness of the loins, are so prevalent. 
In this district, (Ghazepore,) which is considerably higher, 
we have much less of those diseases than in Tirhoot; and in 
the upper provinces they are still less known, particularly where 
the climate and soil are drier. Wherever the situation is low 
and damp, and the easterly wind prevails, more of Kumree 
and worm in the eye will be found ; and vice versa. If the 
worm in the eye depended on any quality of the food or water, 
I think it might be seen throughout the year, instead of being 
confined to,a certain period. 
I have always been disposed to think, that the worm in the, 
eye must find its way into that situation through the circulat-. 
ing system, and not from without. 
The same causes which produce the worm in the eye, ap¬ 
pear to me to induce the weakness in the loins. Both are found 
to prevail in similar situations; but with this difference, that 
the weakness in the loins may, and does take place at all sea¬ 
sons of the year. It, however, most commonly takes place in 
the cold months, particularly in October and November, though 
I have seen cases occur every month of the year, when the cattle 
were in the highest possible health previous to their being affect¬ 
ed with the Kumree. The attack of the disease is almost always 
sudden, and without any previous indisposition. 
I have more than once seen two worms in the same eye at 
one time ; and have also seen a second worm make its appear-
