INTROSUSCEPTION OF THE C.ECUM, &c. 
effusion in the thorax. The heart itself was sound, with the ex- 
ception of its covering. 
Observations . — This cow was accustomed to lie down more 
than usual preceding her death, and the action of the heart was 
only heard to beat so strongly when driven about or excited, and 
which would subside after she had been standing quiet for a 
time. 
This I consider to be a very rare case. 
INTROSUSCEPTION OF THE CLECUM, AND WORMS 
OF A PECULIAR SORT IN THE CAECUM AND 
COLON OF A HORSE. 
By the same. 
About six in the morning of the 28th of January, 1842, I was 
called to attend a valuable five-year-old cart horse belonging to 
Mr. Daniel Sumner, of this town. He had not been out of the 
stable, except to the water, for some days, and was considered to be 
in perfect health. He had never had any thing wrong with him, 
nor was he having more than a quartern of corn a-day. About

and in about a quarter of an hour afterwards he died. He was 
not in the least swollen. 
Post-mortem examination . — There were about two gallons of 
serum in the abdomen. The stomach was sound, and about half 
filled with partially digested food. I cut open the w'hole tract of 
the small intestines, and found that they contained little food, but 
a large quantity of mucous secretion, and they had the appear- 
ance of being slightly inflamed, or in such a vascular state as 
would produce the increased secretion. There w 7 as less secretion 
about the ileum. 
On arriving at the csecum I could scarcely make out in what 
shape or state it w 7 as, and thought at first that it was strangulated 
or maLformed ; I therefore had it removed to my house, where I 
found that nearly the whole of it had disappeared, but on farther 
examination I discovered that it was completely turned inside out, 
and was lying in the colon. That portion of the cmcum w as scarcely
