CASES OF PALSY IN THE HORSE. 283 
vent the accumulation of urine. Her food consisted principally 
of gruel. 
1 6th .—There was little change. She dunged twice, with 
slight effort, after the administration of injections. The quantity 
of urine which was taken from her at different times by means 
of the catheter was about nine pints. It was thick and bloody. 
In the course of the day the disease seemed to be aggravated, 
notwithstanding which she regained a little sensibility in her 
hind limbs. The attempt was often made, but fruitlessly, to 
raise her. She gradually became weaker. The same treatment was 
prescribed, and she was turned on the other side. At six o’clock 
in the evening fifteen or twenty punctures were made over 
the loins, and which were followed by long and powerful friction 
with ammoniacal liniment. The punctures did not appear to 
give any pain. During the night the fore limbs were constantly 
in motion. The pulsations were 90, and the respirations 70, in 
a minute. The urine which was drawn from the bladder re¬ 
tained the same character. The mare drank with ease some 
white water which was offered to her, and she seized with avidi¬ 
ty a little hay, which she tried in vain to eat; the position in 
which she was prevented her. 
17th .—The agitation is so constant and violent that it is im- 
possible to feel the pulse ; the weakness is excessive, and the 
sweat gushes from every part of the body. Sensibility is nearly 
returned to the hind limbs, and the least prick on them causes 
convulsive movements over the whole of the body. Renewed 
frictions on the loins and hind extremities with the ammoniacal 
liniment were ordered ; the other treatment continuing the same. 
She died at nine o’clock on the following morning. 
Post-mortem examination two hours after death .—The diges¬ 
tive and respiratory apparatus were perfectly sound. The bladder 
was moderately distended by a fluid like that which had been 
drawn from it during the two preceding days. Some ecchy- 
moses were observed on the mucous membrane which covered the 
base of the bladder*. Large spots of ecchymosisf were seen 
* The frequent sympathy of the urinary organs, and particularly of the 
bladder, with diseases of the membranes of the spinal canal in the horse, 
is a fact worthy of observation. We have opened many that have died of 
vertiginous affections, and in most of them the urine voided during life 
was of a high colour, or tinged with blood ; in all of them the mucous mem¬ 
brane at the base of the bladder was marked with red spots, more or less 
large or numerous, or exhibited a singular arborescent or dark-coloured 
injection. 
+ These ecchymoses are almost always met with in horses whose death 
is attended with violent struggles.
