toms, protrusion of membrana nict.itans, cocking of tail, etc. 
The jaws were also set so that it was only with the greatest diffi¬ 
culty I could administer a ball. 
Not knowing exactly what to do I prescribed T. E. Physos- 
tigma, gttx, spts. vini., recti., 3 iv, every two hours. Next 
morning tetanic symptoms had almost entirely disappeared, and 
the mare made a good recovery under ordinary hygienic and 
stimulating treatment. 
The other cases were almost precisely like the above, and all 
made speedy recoveries. 
OPIUM POISONING IN THE HORSE. 
By M. T. Treacy, M.R.C.V.S. 
The following interesting case recently occurred, and, not 
having seen any similar ones recorded, I venture to enclose it for 
publication : 
On my arrival at my office, (having been absent all day), on 
the evening of January 2 d, I was requested to attend at a stable, 
where, the messenger said, a horse had gone crazy. I found my 
patient, a fine six-years-old bay gelding, about 1,200 pounds, in a 
loose box, with his head pressed forcibly against the wall, his 
limbs describing automaton movements, as if walking, his ears 
erected on the slightest sound, body covered with sweat; pulse 
70, soft and full; respiration 78; temperature 101 ; caloric of 
extremeties good ; pupils much dilated. Occasionally the nose 
would be extended upward against the wall as far as he could 
reach, and remain in that position for one or two minutes, the 
disposition to go forward so well marked, that in the treatment, 
when active exercise was ordered, it took two men on each side 
to restrain his movements to a quick walk, and he couldn’t be 
made to stop, unless by allowing him to rest his head against a 
solid body. He was mean in disposition and ugly to approach. 
History. —Been treated for intermittent colic all day in my 
absence and had received eight or ten drenches, the contents of 
which I could not learn.
