ON THE MARSH DISEASE IN THE HORSE. 
The principal lesions that are observed are found in the region 
of the joints. The tissues are infiltrated with a yellow serosity, 
the quantity of synovia is increased, and the articulations are more 
or less enlarged. Sometimes there are spots of inflammation on both 
the small and large intestines. 
This malady, of which no one, notwithstanding its present appear- 
ance, has made mention, and which we have not been enabled to 
study in all its phases, leaves considerable doubt as to its etiology. 
So far as our observations have extended, we have traced its prin- 
cipal causes to the state of the mother. Whether her food has been 
of too exciting a nature, or she has been placed in moist or ill-ven- 
tilated situations. 
The remedy consists in submitting the mare to an antiphlogistic 
treatment, and giving gruel, and straw, or but a small portion of 
hay. The little patient should be placed on fresh litter, and friction 
with camphorated spirit or turpentine or ammonia applied to his 
limbs. If the animal cannot get up without much difficulty or pain, 
it must be brought many times in the day to the mother, and held 
to the teat as long as it will suck. If these measures appear to 
have little effect, vesications must be applied to the diseased parts. 
Costiveness must be obviated by emollient injections. If it will 
not suck, or has not learned to suck, the milk should be drawn 
from the mother, and he should be plentifully supplied with it.

[This disease, so graphically described by M. Canu, is no stranger 
to several of the low and marshy districts of this country, although 
it has not yet found an historian of its cause, or symptoms, or 
treatment. We trust that some of our numerous correspondents 
will give us their experience of it. They would be doing our 
profession service. — Y.] 
This malady — the name of which is erroneous, since it some- 
times developes itself among animals that have not been bred in 
the marshes, but whose temperament is naturally lymphatic — has 
not yet, that I am aware of, been particularly described : never- 
theless it has often disconcerted our veterinary surgeons in every 
part of our country, by the frequency of its appearance and the 
number of its victims. 
The marshes in the neighbourhood of Isigny belong to those 
who live by the banks of the river, and who send thither a greater
