ANEURISM OF THE AOIITA, &C. 
made to move out of the stall. Immediate examination gave the 
following result : — The mare stood with her legs, both before and 
behind, wide apart; with her head in the manger, leaning her neck 
on its edge, with chest firmly fixed against it. She had lost all 
consciousness ; the respiration was deep and sonorous ; the eyes 
protruded; the pupils dilated ; the upper lids drooping, and moved 
convulsively; the mucous membrane dry and red; increased tem- 
perature, particularly about the forehead; pulse full and hard, 
50 beats per minute. These circumstances strongly indicated vene- 
section should be forthwith resorted to; but the narrow stall in 
which the mare stood, and the loss of consciousness, necessarily 
caused some delay ; and it was thought expedient to remove the 
patient to the adjoining riding-school. The bleeding was effected 
in a strong stream until the pulse became less full and softened, and 
the contraction of the heart became more marked. Cold water, in 
which ice was immersed, was applied to the head during the bleed- 
ing, and continued afterwards. The patient after the bleeding, 
which was a copious one, was slowly walked about the riding- 
school : such, however, was the effect of the venesection, that it 
became necessary to support her. Several persons had to walk 
by her side, to prevent her from falling. 
The following prescription was ordered : —

One table- spoonful to be given every two hours. 
17 th . — Consciousness in some degree returned. Pulse soft, 4*2 
per minute. Contraction of the heart perceptible; respiration more 
free; temperature even at the head; moderate alvine evacuations, 
frequent, and in large quantities, but badly digested. The mare 
drank a little water from time to time, but deglutition was yet 
very irregular. The treatment the same. 
18^A. — The patient carries the head still low, but moves with 
more freedom, and without support; has eaten a small quantity of 
wet bran and some hay : pulse 34 ; contraction of the heart per- 
ceptible; respiration regular and free; mucous surfaces of a more 
natural colour than yesterday ; alvine evacuations soft ; tempera- 
ture of the body decreased. By removing the clothing some iso- 
lated beats of the pulse were perceptible on the back, similar to 
those described in the former cases. On a second examination, in 
the afternoon, these had become more distinct. From this appear- 
ance it became evident that the congestion of the brain in all pro-
