SUSPECTED POISONING. 
The operation occupied forty minutes, but the mare went 
on very well afterwards. 
This made the twenty-third case in which I had performed 
embryotomy on foals and calves during the winter and 
spring of 1859, besides great numbers that I extracted during 
that period without resorting to this operation. 
Case 2.—Mr. Chadfield, of Prodsley Wood, had a mare 
that could not foal, from the same cause as the above, and I 
operated in the same manner, only I brought the head of the 
foetus forward, when the fore extremities were removed bv 
fixing a hook in one of the orbits. With the assistance of 
my son this foal was extracted in thirty-four minutes. 
Case 3. —A mare belonging to Mr. John Haywood, of 
Ashbourne Green, was unable to parturiate, from the head 
of the foetus being turned back. I found the fore legs pro¬ 
truding as far as the knees, as in the other cases, and I 
operated in the same way as before described. I was nearly 
an hour in extracting the foal in this instance, arising from 
the extreme violence and throes of the mare; nevertheless, 
this animal likewise did well. 
I seldom find much difficulty in extracting foals or calves 
in presentations of this kind, unless there is some malforma¬ 
tion either in the parent or offspring. 
Case 4.— My last case of this kind shall be an unsuc¬ 
cessful one. It occurred in my practice, eight years since, 
and it brought on an eruptive disease in my arms, called by 
some writers ecthyma simplex, which has troubled me very 
much, more or less, every year since, during the parturition 
season. 
CASE OF SUSPECTED POISONING. 
By E. O. Harrison, M.R.C.V.S., & Y.S. Royal Artillery. 
Tiie subject from which the morbid specimens sent were 
taken, was a small, thorough-bred, gray horse, my own pro¬ 
perty, four years old. He had been ridden as a hack by 
me for about twelve months, eleven of which he enjoyed, to 
all appearance, good health. He was vigorous in his move¬ 
ments and pleasing to the eye.
