ON CHOLERA IN DOMESTICATED ANIMALS.

and the muscles of the loins and quarters, took place, which lasted 
for some time. Next day she was much better, and in a week 
was as well as ever. 
Upon these two cases, however, I do not intend to found any 
particular remarks, as the symptoms may have arisen from some 
accidental injury: if that was not the case, they shew what I 
have w'ished to impress, a tendency to disease in all the mucous 
membranes. 
From what has been stated, it will, I think, appear pretty 
evident that there has existed, for about these twenty-two months 
past, an epizootic affection of the mucous membranes, especially 
in the horse; and it must also appear, that that affection has 
offered some peculiarities in its character, which deserve atten¬ 
tion. While, in the commencement, it was clearly an affec¬ 
tion of the mucous membrane of the respiratory organs, there was, 
at the same time, a more than ordinary degree of excitability of 
the mucous membrane of the intestines, and which was indicated 
by the violent effects which small doses of medicines produced 
upon them. This irritability of the membranes has continued 
even until the present time. While, however, the malady seems 
to be but little altered since its first appearance, there has been, as 
will be observed from what I have stated, a still greater 
determination of disease to the mucous membrane of the 
intestines than at its commencement. The latter form of 
the affection is the more remarkable, because, while the horse 
is sufficiently liable to diarrhoea from over-exertion, in com¬ 
bination with bad food or improper feeding or being allowed 
too much water prior to this severe work, he is, at the same 
time, so little subject to diarrhoea while at rest, or under pro¬ 
per diet and exercise, that I have been for years without meet¬ 
ing with a case. When that is compared with the occurrence 
of so many as I have enumerated, and taking place in so short a 
period, and under the present peculiar circumstances, I feel 
compelled to come to the conclusion, that the same causes which 
have been operating upon the human being, have also been affect¬ 
ing the lower animals; and it may, therefore, not be improper 
that I should offer my opinion regarding the identity of the dis¬ 
ease in man and in brutes. 
Soon after the appearance of the cholera in Musselburgh, I 
had occasion to make a visit at Preston Pans; and, on my re¬ 
turn home, in coming through Musselburgh, I happened to be 
passing just as some medical gentlemen came out from visiting 
a case; and I was informed by one of them, whom I chanced 
to know, that I might see it, if I chose. I embraced the oppor¬ 
tunity, and found the poor woman in a state of collapse, and at
