CHOLERA IN A MARE. 
seed, and, while the waggons were shifting about, the trace horse 3 
were put under a very tine yew-tree which stands in the 
rick-yard, and were seen cropping the tree by the carter; but 
he was totally ignorant of its baneful effects on the animal body. 
They died within three hours of the time they took the yew. 
The driver said he did not perceive any symptom of the slightest 
derangement or incapacity in either of them until they staggered 
a few paces—fell—and, before the harness could be taken off, 
were dead. 
I think there can be no doubt but that they were poisoned by 
the yew. 
I shall feel much pleasure in sending you the result of some 
experiments on the first subjects I meet with designed for the 
dogs. 
CHOLERA IN A MARE. 
By Mr. E. C. Bull, F.S. Huntingdon. 
A very singular case has fallen under my observation, a de¬ 
scription of which will not, perhaps, be thought unworthy of 
notice. 
I was called at 5 p.m. on the 15th of the present month, to 
see a mare, five years old, with a foal of six months, belonging 
to Mr. Knighton, of Huntingdon. She was perfectly well in 
the morning; but I found her at the time stated very much 
tucked up, voiding copious watery stools, of a foetid smell and 
dark colour; the pulse at the submaxillary artery quick and very 
feeble; extremities very cold, the nose and ears particularly so; 
the eyes very dull; the breathing much oppressed; and there 
seemed to be suppression of urine. I bled her, and obtained 
with difficulty three quarts of dark treacley blood. I gave her 3j 
of laudanum and 3j of spt. nitrous ether, and administered an 
injection of laudanum and starch. 
7 o'Clock .—Much the same. I attempted to bleed her again, 
but could obtain only half a cup full. I repeated the injection, 
and blistered the belly largely. 
On the morning of the 16th she was much worse. I repeated 
the injection, allowed her to drink five quarts of warm w 7 ater, 
and blistered the legs. 
II o'Clock a.m. —Purging stopped; pulse not to be felt; 
breathing very difficult; tongue blue, cold, clammy; the lips 
also very blue. 
1 o'Clock p.m. —She fell down as if cramped; voided more 
faeces, of a much lighter colour, frothy, and with a putrid smell;
