POISONING OF CALVES WITH RHODODENDRON.

The horse being cast in the usual manner, the hind legs 
were brought well forward by the collar-rope used in cas¬ 
trating. A sponge, partly covered with oil-silk, and satu¬ 
rated with chloroform, was applied to each nostril, and in 
eight minutes he was completely under its influence. The 
sponge was now removed from one nostril, and the anaes¬ 
thetic influence kept up by ether. 
Assisted by my friend Mr. J. M. Riches, Y.S., Acle, a 
whalebone staff was passed up the urethra in the usual 
manner, and cut down upon in the perinaeum. A pair 
of spoonbill forceps was then introduced, and the cal¬ 
culus firmly grasped, but in extracting it it was partially 
crushed. A second introduction, however, of the forceps, 
withdrew the remainder; the bladder was then washed out 
with tepid water, and one suture applied to the "wound in 
the perinaeum. 
The blood lost was inconsiderable. 
The horse was then let up, and the time occupied from 
first using the chloroform to the end of the operation was 
found to have been twenty-five minutes. 
The weight of the calculus was over three ounces. 
The patient was now taken to his box, and in about an 
hour after he staled, the urine coming through the wound 
and natural passage. 
On the 15th the suture was removed, and the wound 
cleansed with tepid water. The animal still urinated partly 
through the wound and partly by the natural passage. 
The same treatment was pursued till the wound finally 
closed, which was on the 20th of March. He left my esta¬ 
blishment on the 29th, was ridden by his owner on the fol¬ 
lowing day, and remains in his possession up to the present 
time, being constantly ridden and driven by him. 
POISONING OF CALVES 
WITH THE RHODODENDRON HYBRIDUM. 
By B. Kettle, .M.R.C.V.S., Market Drayton. 
Conceiving that the following cases of poisoning of 
calves with the Rhododendron hybridum —from their novelty— 
may have some features of interest for the profession, I beg 
to place them at your service. 
Early in the morning of January 8th, 1858, I was re-
