REPORTS OF CASES. 
At seven o'clock he gave out, settling back in the slings so that 
he nearly slipped out backwards. The slings were then removed, 
and he continued lying down. He was seen up but. once after 
this, and then only for a few minutes. On the 1st of September 
he was thrashing about, so that he was pithed late in the evening- 
At this time he had complete paralysis of both hind extremities. 
On post-mortem examination nothing wrong was noticed un¬ 
til, while trying to exhibit the spinal marrow, we reached the 
seventh, eighth, ninth and tenth dorsal vertebrae of this region- 
A large clot of blood ,was found in the muscles, which were be" 
sides thickly infiltrated with blood in their entire thickness, the 
annular portion of these vertebrae being also more or less dis¬ 
eased. The seventh presented a small necrotic surface at the 
base of the posterior border of the superior spinous process. The 
annular portion and base of the spinous process were destroyed on 
the right side of the median line, the necrosis extending through 
the bone into the spinal column. On the ninth the necrosis was 
not quite so extensive. It appeared principally towards the 
transverse process, but there also were perforating the bone right 
through. The tenth presented only slight necrosis at the base of 
the transverse processes. The vertebral canal was filled with, 
blood, and the spinal marrow too much softened to permit any 
examination. 
All the other organs of the body were healthy.

ACUTE RHEUMATISM. 
By H. F. James, V.S. 
Was summoned October 5th, about 4 p. m., to attend a bay 
horse which had been exposed for some hours in the rain two days 
before, and was now reported to be very sore, and entirely off his 
feed. On examination found temperature 105°, pulse 75 and 
wiry, respiration 50 and very laborious. Fore legs, especially the 
knees, and the hind legs from the hocks down exquisitely tender 
to the touch and swollen. Diagnosis—acute rheumatism; prog¬ 
nosis—doubtful on account of the great respiratory disturbance, 
which indicated implication of the valves of the heart. Admin-
