490 OBSERVATIONS ON ETHER AND CHLOROFORM. 
present when the benefit is most speedy. At the end of the half 
hour the horse was so much better that I left him, and saw him 
again about half-past eleven at night, when I found the animal 
comparatively quiet, but still evidently suffering pain. Four 
ounces each of ether and tincture of opium, with half an ounce of 
the tincture of aconite, was given as a drink, and a tobacco smoke 
enema administered, and the symptoms after this gradually dimi- 
nished. The horse became more composed, and the nasal mem- 
brane moist, and the animal was obviously disposed to sleep. 
As the tympanitis, however, remained, I ordered some men to 
kneed the right side of the abdomen, and kept them thus em- 
ployed for half an hour, at the expiration of which period there 
was a partial perspiration. The upper lip was no longer curled. 
There was no turning of the head toward the flank, and the danger 
seemed to be passed. 
At two o’clock in the morning I considered the case all but 
well, and gave a drink composed of solution of aloes, seven 
ounces; spirit of nitric ether, four ounces; tincture of opium, 
two ounces ; tincture of aconite, half an ounce ; and tincture of 
ginger, an ounce. 
Some of my professional brethren may think I was tardy in 
resorting to the use of aloes, but, for reasons which are obvious, 
I object to their employment during the existence of acute symp- 
toms which are indicative of colic in any of its multifarious forms. 
I now left a man to sit up with the horse, giving order that if anv 
change, however slight, took place, I should be immediately called. 
At five o’clock I was summoned, the messenger saying “the 
horse was taken suddenly worse, and would die.” I found all the 
old symptoms had returned, but in an aggravated form. The ears 
and extremities were cold ; the nasal membrane of a leaden hue ; 
the eye haggard ; the breathing, if possible, even quicker than on 
the first occasion. My hopes new grew small, and I feared that 
the case would end in death v Knowing that the most powerful 
agents after some time lose their effect upon the system, I was 
less confident in the operation of ether, which hitherto had done 
me such good service. I determined to try the effect of chloroform, 
and, combining six drachms by measure with half a pint of olive 
oil in which two drachms of camphor had been rubbed down, 
I gave it to the horse, also repeating the tobacco smoke enema. 
The effect was almost immediate, and none of those symptoms 
which ether induces were observed. At the expiration of an hour 
I saw no necessity for doing any thing more, nor did I, in the 
course of the morning, find occasion to administer any thing fur- 
ther. Towards noou the horse was looking out of box and watch-
