W. J. COATES. 
as the following case will illustrate, which recently came under 
my notice, and well worthy the attention of the members present. 
Dr. J. J. Murray, of this city, was called September 3d, 1883, 
to see a bay gelding, seven years of age, fifteen hands three 
inches high, as to roaring, with the following history, which is 
somewhat deficient: The animal was purchased a few months 
previous, and on the slightest exertion would roar and would be¬ 
come much exhausted after being driven for a short distance; 
appetite poor: some days would cat a fair quantity, other days 
hardly a quart. The owner was advised not to treat him, as it 
would be an expensive pleasure, and nothing more was heard of 
the animal until September 23d, when the doctor was hurriedly 
sent for to attend a horse which was very restless and acting 
similar to a mild case of colic. On arriving at the stable, he 
found the same horse, which had been sold by the previous 
owner September 12th, and stated by present owner that ever 
since he purchased him he had not been in good health ; that on 
being driven a few blocks, he would begin to roar and become 
exhausted, sometimes staggering from side to side; great diffi¬ 
culty in breathing, and at times showing symptoms of vertigo. 
After being rested for an hour or two, ail the symptoms 
would subside. While standing in his stall he would paw occa¬ 
sionally, restlessly ; would rest his head on the partition of the 
stall, and when any one approached him, would become excited 
and toss his head from side to side ; has eaten very little, and 
to day refused his food. On being backed out of the stall, it was 
noticed that his jugular veins were pulsating and the heart’s ac¬ 
tion considerably increased. A messenger was sent to me to 
come immediately and consult in a case of palpitation of the 
heart. I being away, and not to return till midnight, a sec¬ 
ond message was received to call in the morning. On arriving 
Monday morning, September 24th, found the animal presenting 
the following symptoms, which had slightly abated : Cyanotic 
condition of the mucous membranes, veins of head and neck dis¬ 
tended, pulse irregular and feeble, respiration slightly increased 
and difficult, temperature 102° F. ; jugular veins greatly dis¬ 
tended, and pulsating irregularly. Physical examination, on in¬ 
spection : Cardiac impulse lifting the side of the chest; on pal
