had been applied, while these had to be put on afterwards to 
prevent bleeding, everything went well and the results were 
satisfactory. In the other there was no trouble and the animal 
recovered in a few days and remained in that condition for about 
two weeks, when she began to be excited and exhibited symp¬ 
toms of nymphomania. She rapidly grew worse, became dan¬ 
gerous and was going to be destroyed when she got severely in¬ 
jured and was ultimately sent to the abattoir. At the autopsy 
the left side was found in good condition ; elastic ring and pearl 
well in place and, so to speak, encysted in a fibrous mass con¬ 
taining the atrophied ovary. But on the left the ovary, elastic 
ring and pearl were there also, but the ovary was greatly con¬ 
gested and engorged, and about twice its normal size ; the ring 
was, it is true, around the utero-ovarian ligament, but loose, and 
the pearl was broken in some twenty little pieces, floating in

Spontaneous Rupture of the Perforatus Tendon 
in A Horse \By Prof. T. Hendrickx \.—The author calls 
this rupture spontaneous as being a solution of continuity 
of a tendon occurring without well marked traumatic cause. 
It is the history of a large draught horse which was placed un¬ 
der his care suffering with pneumo-enteritis. Although he 
recovered from this, he had a peculiar gait. Sent back to work, 
he was, after ten days, brought back to the Hospital of the Vet¬ 
erinary School of Cureghem, suffering with purpura. Failing 
to get good results from the serum treatment, Prof. Hendrickx 
resorted to the use of argentum colloidate, so much recom¬ 
mended by German authors. After an injection the improve¬ 
ment was well manifest, but then appeared the last complication. 
The animal stood peculiarly on his right hind leg, the fetlock 
had dropped, the hock was extended and the os calcis much 
lower on the right than on the left side. Made to move, the 
manifestations were becoming more assured, the animal rested 
with the fetlock on the ground and the os calcis dropped still 
farther down. The animal was destroyed. On dissecting- the 
right hind leg, it was found that the perforatus was com¬ 
pletely ruptured a little above the fetlock, on a point correspond¬ 
ing to the spot where it forms a ring for the passage of the per- 
forans. The ends of the tendon were irregular, with disassociated 
fibres and haemorrhagic points. Similar lesions existed on the 
left leg also, but to a lesser extent. The texture of the tendon 
was quite firm, with haemorrhagic spots and even a beginning 
of rupture. Had the animal lived, the same symptoms would
