In the second case, the salient feature was the occurrence 
of a round tumour, of a reddish colour, on rhe external part 
of the rectum, at the extremity of which was an orifice, into 
which the probe easily penetrated. This tumour was readily 
reduced by elevating the posterior part of the animal, and 
using slight pressure on the parts, when it would return to 
its natural position. The faeces were soft, but voided 
with difficult}^. The animal evinced some slight abdominal 
pain ; was dull, but, nevertheless, took what was given him in 
the way of food. The mucous membranes were ingested ; 
the pulse quick and small. The reduction of the parts was 
made, and mucilaginous drinks and injections were ordered, 
which seemed to produce some amelioration, lasting, how¬ 
ever, but twelve days, during which time the intestine did 
not protrude. After this period, the prolapsus returned, all 
the symptoms were aggravated, and the defaecation was con¬ 
tinual, painful, and in small quantities. The next day there 
was loss of appetite ; the mouth was hot; the flank was 
tucked up ; the protrusion of the intestine was increased, 
and had assumed a purple colour, and faecal matters of a 
sero-mucous nature and a fetid odour escaped in small quan¬ 
tity from the intestines. These symptoms increased in 
intensity, with but slight interruption, for about a week, 
when the animal died. On opening the abdominal cavity, 
the following abnormal features were brought to view. 
The large intestine was turned back, and presented a 
number of large folds; the rectum was distended, as if 
by a cylindric, resisting body. On incision it was found 
that this cylindric body was formed by a portion of the 
small intestine, of about twenty-five centimetres in length. 
Upon introducing a probe, it penetrated without any great 
difficulty into the large intestine ; there was, nevertheless, 
some resistance to overcome at the commencement of the 
part of the intussusception, at the point which corresponds 
to the adherence externally of the two tunics of the large 
and small intestines. The coats of the large and small 
intestines, anterior to the invagination, strongly adhered 
to each other, to the extent of eight to ten centimetres. 
This adhesion was formed by a sort of semi-membranous sub¬ 
stance, of a whitish-red colour; but separation having been 
effected, the intestines were easily replaced in their normal 
position. The invaginated intestine had traversed the whole 
of the larger intestines, which must have exerted an anti« 
peristaltic contraction ; the faeces could pass through the 
whole length of the tube, meeting only with a slight obstacle 
at the point of adherence above mentioned. If the subject
