RUPTURED DIAPHRAGM AND DISEASED STOMACH. 427 
seemed to be tom from the tendinous portion. It was evidently 
a recent affair, as there was not the least disease about it. 
The Stomach. — The villous coat was very much thickened, 
soft, and of a dirty colour, and could easily be separated from 
the muscular. 
The cuticular coat had been much eaten through with bots, 
but the stomach was free from them at present. All along near 
the side of the villous coat (cuticular) it was eaten away en- 
tirely through. In one place there was a continuous patch 
six inches long, and varying in width from an inch to a quarter 
of an inch. Others were two inches long, and everywhere there 
were isolated spots of different sizes. 
These were entirely through the coat, for in stripping it off 
holes were left in it. All around these eaten spots the coat was, 
as usual, much thickened and whiter. On some parts of the 
cuticular coat there were portions of from two inches square to 
various less sizes, that had evidently been eaten through, but 
which was secreted again ; they had a smooth appearance with 
a bluish cast, and on separating it from the other coats it was 
found to be very thin and easily torn. In some places the cuti- 
cular coat was eaten through and away close up to the villous 
coat, but they seemed not to have eaten the latter. There were 
also holes in it close up to the oesophagus, but not any in it. 
It is the belief of most veterinary writers that bots do no 
harm ; but I certainly am not of that opinion : for can it be 
supposed that, when there are such extensive parts eaten away 
quite through to the muscular coat, and to which I have no 
doubt great numbers of bots must have been a short time ago at- 
tached, they do not cause continual irritation and pain ? I think 
it impossible. Whilst they are merely attached to the cuti- 
cular coat , I believe they can do - no harm ; but in the case 
I have just related there must have been nearly a quarter of 
the cuticular coat destroyed quite through to the muscular ; con- 
sequently there must have been a continual gnawing pain while 
they were attached to it, and also after they had been expelled, 
for an abraded surface was left exposed to the rough indigested 
meat, and which would continue until fresh cuticle was formed. 
The Editors of The Veterinarian seem to be of a different 
opinion, viz. that they do not penetrate the cuticular coat, but 
are merely attached to it. Now in almost every case that I have 
seen (and I have noticed them particularly) they are not only 
attached, but in most places they have eaten through the coat, 
and left holes in it from the size of a pin’s head to those great 
patches related in the foregoing case. I certainly see them, in
