NEPHRITIS AND PARAPLEGIA.

greater or less time in the stable. Some of them fell almost im- 
mediately on going out of the stable — others after a long journey 
in which they had worked well ; but not one of them had eaten 
from the time of his leaving the stable to the moment of attack. 
Until their death, they voided, from time to time, urine, varying 
in colour from brown to black. The respiration was much dis- 
turbed, as was the circulation. All of them had a painful tenes- 
mus, and used the most violent efforts to evacuate their faeces, 
but in vain. They uttered plaintive cries and groans — their 
bodies were covered with a cold sweat, and yet some of them re- 
tained their appetite to the last. These symptoms continued to 
increase, excepting that they had a few short moments of re- 
mission. 
M. Mannechez, who had seen many more cases of this kind 
than had fallen to our lot, believed that these attacks w r ere al- 
ways fatal, and certainly he had not succeeded in a single case. 
In the many post-mortem examinations made by him, he found 
that the envelopes of the spinal marrow in its lumbar portion con- 
tained an abundant serosity of a citrine colour, and sometimes 
gelatinous, and which he considered as the immediate cause of 
the palsy. Sometimes, but much more rarely, he found sanguine- 
ous congestion in these regions. 
At the same period, many horses that had been fed and worked 
well, were destroyed by gangrene, with perforation of the poste- 
rior extremity of the floating portion of the colon, or to a certain 
extent of the rectum. The symptoms w'ere, extreme anxiety — if 
the word may be used as expressive of any state of the quadru- 
ped — with very short remissions — the respiration laborious, preci- 
pitate, and short — the pulsations of the artery and the heart syn- 
chronous with the flanks — the eyes starting from their orbits — 
the alee of the nose distended and immoveable — obstinate consti- 
pation — frequent straining without any evacuation — the anus hot 
and projecting — cold and abundant sweats about the prepuce and 
the thighs — hardness in the region of the kidneys — the penis pen- 
dant — frequent and violent efforts to expel a few drops of brown- 
coloured urine — emptiness of the bladder and the impossibility of 
retaining the smallest portion of an injection — continual looking at 
the flanks — lying down and immediately rising again — locomo- 
tion easy, and the utter loathing of food. The attack is sudden, 
and the progress of the disease most rapid — death supervening 
in twenty-four, forty-eight, or seventy-two hours at the most. All 
treatment useless. 
Lesions after death. — Gangrene of all the membranes of some 
part of the floating portion of the colon or the rectum, about a
