438 OBSERVATIONS ON SOME DISEASES OF THE HEART. 
was effected, and every unfavourable symptom disappeared. 
Barley gruel sweetened with honey was ordered, and emollient 
injections. 
2Ls£. — The appetite returned, and he seemed to have quite 
recovered. He passed the winter in the stable, and, although 
somewhat thin, was in fair condition. 
2 6th May , 1835. — He was sent to grass, and speedily got 
into condition. This continued until the month of September, 
when he fell off altogether as rapidly, which was attributed to 
the dryness of the season, and the little grass which the pasture 
afforded. 
He was taken up on the 1st of October, and appeared gradu- 
ally to recover his strength and spirits. 
Nov. 1. — He was seized with a tremulous motion of several of 
the muscles — he heaved at the flanks — his head drooped — -his 
pulse was very small, and much accelerated — the conjunctiva 
was red — the skin very cold — the submaxillary glands enlarged. 
Presuming that strangles were preparing, I gave him drinks of 
warm cider, sweetened with honey ; plenty of friction was ordered ; 
and a seton was inserted in the chest. 
Nov. 2. — Every unpleasant symptom had nearly disappeared. 
March 15, 1836. — There was a new attack of disease, with 
considerable itchiness of the skin, and eruption about the abdo-

after a hard day’s work, yet from which he had not shrunk, and 
after a few gambols with his heels, to shew that he was neither 
tired nor hurt, he began to stagger — he refused his food ; this 
peculiar tremulous motion spread all over him — his flanks heaved 
precipitately — his pulse became small, irregular, and intermittent, 
and, at length, imperceptible. He fell on his litter, and was dead 
in twelve hours. 
Examination after death afforded nothing extraordinary, ex- 
cept a considerable effusion of red coloured fluid in the pericar- 
dium. Every other organ was in its natural state. After these 
observations, we may conclude : 
1. That disease of the heart in quadrupeds is less rare than 
has been generally supposed, and that therefore it is the duty of 
practitioners to observe and to record every symptom that may 
indicate its existence. 
2. That the attacks of carditis and pericarditis are sudden and 
irregular in their appearance, and in their intervals. That the 
attacks are more serious as the termination of the disease ap-
