heal by first intention. This section with the cautery has sev¬ 
eral advantages; it secures complete antisepsy of the two nerve 
ends, a sufficient cauterization to prevent their reunion and the 
return of sensibility. While all accidents may not be pre¬ 
vented, it is-certain-that they will be less frequent by this 
mode.— {Rec. de Med. Veterin.) 
Rupture of the Spleen in a Horse [M. Pruneaii \.— 
A four-year-old received a kick on the right hypochondriac re¬ 
gion. Swelling as big as a hen’s egg, growing gradually, and 
soon extending to the abdomen and left side of the chest are 
the consequences. A few days later, while being tied up, he 
pulls backwards, the rope of the halter breaks, and he is vio¬ 
lently thrown back, and after getting up falls down again, and 
remains unable to rise. Then his breathing is slow, loud ; 
there is abundant perspiration ; the mucous membranes are pale; 
the pulse cannot be felt; the pupil is dilated ; the beatings of 
the heart strong but separated ; rectal temperature 36.8° C. In¬ 
ternal rupture following fracture of the vertebral column is the 
diagnosis. After a time, and with much difficulty, the horse 
gets up and presents the following symptoms : Head and neck 
hanging, hind legs kept apart, hind quarters trembling ; respi¬ 
ration very loud, anus open. The animal died an hour and 
a half after the accident. At the post-mortem, extensive sub¬ 
cutaneous ecchymosis in the cellular tissue. On opening the 
abdominal cavity 12 or 13 litres of blood are found. The spleen 
is quite large, and large clots of blood on its internal face, one 
of which was oozing through a laceration involving the exter¬ 
nal coats of the organ and the superficial splenic pulp. This 
laceration existed along the border of insertion of the suspen¬ 
sory ligament.— {Rec. de Med. Veterin .) 
Synovial Cyst of the Knee in Horses [M. C. Lesbee ].— 
This case shows that synovial cysts may appear not only at the 
hock, but also on the carpus and everywhere when a synovial 
cul-de-sac exists, with a narrow opening, and when the entrance 
and exit of the synovia is permitted only with limited motions 
of the parts. A seventeen-year-old mare has, for several years, 
presented on the external face of the left knee a small tumor, 
as big as a small orange, situated about the suscarpal bone, be¬ 
tween the radius and the flexor tendons of the metacarpus. 
The anterior face of the knee is free from swelling or tumor. 
The walls of the cyst are much stretched when the horse has 
his leg at rest. There is no lameness. The classical treatment 
by injection of tincture of iodine is resorted to and performed
