CASE VI. 
January 23 d, 1834. — I was requested to visit a fine hunter, 
belonging to a gentleman of this town. 1 will give you the 
groom’s account of the matter, as nearly verbatim as possible, 
when he came for me: — “ I cannot tell what’s the matter with 
him. I left him all right last night; but when 1 opened the 
stable-door this morning, he appeared as if he had been dread- 
fully frightened, for you may both see and hear his heart beat 
as soon as you get to the stable-door — thump, thump, thump, 
like a cotton-weaver’s loom.” On my arrival, the appearances 
of the horse fully vindicated the description which the groom 
had given. The spasmodic action of the heart was really ap- 
palling ; the diaphragm seemed to be also affected in a strange 
manner ; and there were contractions of the muscles of the neck 
and left fore-leg. The breathing was not much quicker than 
usual, but very strong and heavy, accompanied with deep sobs 
and sighs at about every fourth respiration ; the countenance 
shewed great alarm, and was fearfully anxious. The least noise 
or disturbance about him threw him into violent agitation. The 
jaws, eyes, ears, tail, and muscles of the body, were not at all 
affected ; nor was there the slightest tetanic symptom. His 
pulse was about 54, very irregular both in strength and time. 
He had not eaten his last night’s hay or com. I took away 12 
pounds of blood, and administered the following medicine three 
times a-day in water-gruel: hydrocyanic acid 30 drops, mag. 
sulph. ^iv, antim. tart. 3ss. 
By the third day all the violent symptoms had, in a great 
measure, subsided, and the appetite was returning. 
6th day . — All appears to be right: discontinue medicine. 
7th day . — Struck off the list. 
In July, 1835, he was again attacked in a similar manner. 
The symptoms being the same, I pursued the same treatment as 
in his former attack, which was attended with the same beneficial 
results ; for in five days he was again considered quite well. In 
September, 1836, he was seized, at a distance of twelve miles 
from home, with precisely the same affection, according to the
