Effects of Coal Gas on a Horse. 
A chestnut horse, eight years old, the property of Captain 
Dowbiggin, on January 24th, was left in one of our boxes 
at night, in a state of health, by his groom. Upon opening 
the door on the following morning, the man was almost over¬ 
powered by the escape of gas. The animal was then stand¬ 
ing in the middle of the box, but he moved towards the door 
and pitched head foremost into the yard; he soon, however, 
got up again. I saw him shortly after, and found the body 
covered with perspiration, the animal breathing excitedly, 
pulse 80, feeble and oppressed, the Schneiderian membrane 
of a peculiar bright scarlet colour; and when made to move, 
he reeled about as if giddy. I had him placed in a loose 
open box, and gave him a diffusible stimulant, consisting of 
Spts. Ether Nit. ; and although for a day or two he exhibited 
slight symptoms of giddiness, no further treatment was 
required. 
It appeared that the animal (a mischievous one), during 
the night, had managed to reach the gas-pipe, and had broken 
it off, and the gas, not being turned off' at the meter (as it 
should have been), had been escaping in considerable quan¬ 
tities into the animal’s box. Moreover, the night being a cold 
one, the groom had stopped up the ventilators, so that the 
gas had no means of escaping from the stable. How long 
this had been going on we could not tell, but from the state 
the animal was in when found, it was evident the effects of 
the carbonic oxide and carburetted hydrogen gases would in 
a short time have proved fatal.
