NEPHRITIS AND PARAPLEGIA. 
Case I. 
Intensely acute Nephritis terminating in Gangrene . 
A grey Norman horse, fourteen years old, of a nervous, san- 
guine temperament, and in extraordinary good condition, be- 
longed to Captain Bouchard. He was seldom ridden by his 
owner, but was exercised for half an hour or an hour by a dra- 
goon. In his food, he was invariably submitted to the regi- 
mental mode of treatment, which was deemed to be quite suffi- 
cient, considering the little exercise that he had. 
He was taken ill on the morning of the 22d of February, 1839. 
The soldier who had the care of him stated that he had formed 
the habit of moving about his hind legs when he was dressed, 
and that he had lately agitated them more frequently and more 
rapidly. When he was mounted he lifted his hind legs higher 
than- he was accustomed to do, and in an evident spasmodic 
way. 
The horse had always fed well,, but his attendant had ob- 
served that for a considerable time he had urined with diffi- 
culty, and always in the sheath — the eyes had a wild appear- 
ance — the head was elevated — the pulse and exterior tempera- 
ture were natural — the posterior extremities widened, and the 
left one principally. At irregular intervals he beat the ground 
with his two hind feet, and that with so much force that it was 
somewhat dangerous to come near to him. Even when he was 
calm and tranquil the violent beating would commence, if the 
hand was placed upon his haunches. If any person attempted 
to lift one of his legs he immediately lay down, and it was dan- 4 
gerous to stand near to him. He still retained a good appetite. 
There was no symptom of fever — the respiration was perfectly 
calm — and the pulse was full, yet soft. 
Diagnosis . — Irritation of the urinary passages, with a slight 
obstacle to the passage of the urine. No present danger. 
Treatment . — Gruel and emollient injections. The dragoon 
who had the charge of him was ordered to lead him about for an 
hour, and to clear his sheath, which had not yet been done. Five 
pounds of blood were abstracted from the left jugular, which was 
rich in fibrine. In the evening some thin gruel was offered to 
him, but he would not touch it. He appeared to be perfectly 
quiet. His countenance did not announce any suffering, and no 
one expected any disturbance being near at hand. 
At midnight we were called, and informed that a sudden and 
fearful change had taken place : he was beating the ground with 
his feet, as if he would tear off his shoes — he shook himself, and 
snorted every minute — he sat on his haunches like a dog — his 
breathing was disturbed — the submaxillary artery was hard and
