ON CHOLERA IN DOxMESTlCATED ANIMALS/ 211 
The disease, in a great measure, subsided in the autumn; but 
as the weather became colder it once more appeared: it frequent¬ 
ly, however, differed in some respects from the former, for while 
it partook of the general nature of the affection, it now seemed in 
the commencement of its attacks to be more directed to the 
mucous membrane of the larynx: it w^as also more frequently than 
before ushered into notice by a shivering fit, during which, 
and as the hot stage commenced, the mucous membrane of the 
intestines was also in some degree affected, and which was in¬ 
dicated by colic pains, and the continuation of the same degree 
of susceptibility of being acted upon which appeared through¬ 
out the whole course of the epizootic, and even now is frequent¬ 
ly observed. 
In the beginning of November, a farm horse, belonging to Mr. 
Oarstairs, Penicuik Muir, died of an obstinate diarrhoea; and 
towards the end of November and beginning of December, 
diseases of the bowels became more frequent than for some years 
past. 
On the 7th of December my attention was more especially 
excited by a horse belonging to Mr. iNP Galium, Plowlands, rvhich 
w’as seized on the previous night with sudden illness, attended 
with purging. He had had moderate work on the preceding day ; 
his food, drink, and exercise had not been altered, except that in 
the morning, at five a.m., boiled barley and chaff and bran mixed 
had been given to him; and he had stood for some time in a shed 
that day, while the cart was repaired. 
About four o’clock on the morning of the 7th, how’ever, he 
was observed to be very ill, with symptoms of colic, purging 
violently, extremely fidgetty, and evidently in great pain. His 
owner was called up, who endeavoured to bleed him, and sent 
for me about six a.m, ; but as I had been engaged dunng the 
previous night with a case until after three o’clock, 1 requested Mr. 
Cheethamto attend him, who found him, when he arrived, about 
seven a.m., in articulo mortis. The person who had been in the 
habit of driving him stated, that on the 3d, 4tb, and 5th of 
the month the horse had been purging slightly, but that these 
symptoms had disappeared on the day previous to his being taken 
so ill, and that he was then considered to be much better. 
After death he was conveyed to one of the fields, during which 
process, immense quantities of watery feeces escaped per anum, . 
with a most intolerable stench. 
The body w'as immediately opened. The abdominal viscera 
presented little appearance of disease; the stomach w^as about 
two-thirds filled wdth food, but offered no particular morbid 
ap{)earancc. The mesenteric veins were turgid with black blood ;
