SCIRRHUS IN THE CAECUM OF A HORSE. 
627 
horse suddenly began to make a clattering noise with his feet, 
and voided a greenish urine very abundantly every time they 
tried to raise him, and which was not accomplished without great 
trouble. In spite of bleedings and gum water, and although the 
animal sometimes seemed to rally a little, all went on from bad 
to worse; the horse continued down, and died on the morning of 
the 29th. 
At noon on the same day a post-mortem examination took 
place. 
The lungs were very healthy; the peritoneum had several 
patches of red in different places, and of various extent, the 
smallest of which were equal to a five-franc piece in size. In 
some of these the colour was simply red; in others, on the large 
intestines, it w^as black ; and within these large intestines the 
membrane was also very much diseased. The ceecal termination 
of the small intestine did not present the slightest trace of its 
original organization; it was entirely seirrhous, and was con¬ 
founded with the folds of the peritoneum, which fixed the ceeciim 
to the sub-lumbar region, and offered the same appearance. 
These membranous parts she\ved in their folds a lardaceous tex¬ 
ture, which in some places w'as four or five inches thick. 
The projection that the small intestine forms within the ceecum 
resembled a very large apple. Several other parts of the caecum 
were scirrhous, and especially its cul de sac, which displayed a 
kernel about the size of a fowl’s egg, the texture of which was 
greyish and very dense. The internal membrane of the colon 
also presented some indurations, around which the membrane 
was of a gTeenish hue and easily torn. The mucus contained in 
the pelvis of the kidneys was very abundant; the mucous coats 
of the ureters and of the bladder were streaked with bloody rami¬ 
fications, or spotted with ecchymoses. 
All these lesions were doubtless of ancient date ; and they did 
not appear to have in any way interfered wath the important 
functions of nutrition, since the animal was fat, and had every 
appearance of health; nor was their formation marked by any 
sensible irritation, for, with the exception of the attack of pul¬ 
monary catarrh, the animal had never been ill. If inflammation 
had presided at the formation of these new tissues, it must have 
been of that very slight character which is generally so little mark¬ 
ed as to have been designated under the name of sub-inflamma¬ 
tion. Perhaps hereafter practitioners will give to this morbid 
growth another name, and will explain it by another theory : these 
theories and these names are not a matter of indifference, for they 
influence the mode of treatment. We have seen, for example, 
that in consequence of exclusive ideas of irritation and inflamma¬ 
tion, lotions and emollients have been applied to the lardaceous
