Osteoma of the Gluteal Aponeurosis of a Horse— 
Removal—Rapid Recovery [By Prof. Almy \.— A geld¬ 
ing had a hard, painless swelling of the external face of the 
thigh. It interferes with its sale and must be removed. 
The animal is in good condition and not lame. On the ex¬ 
ternal face of the thigh, the hairs are staring, and on pal¬ 
pation a hard bony plate is felt of peculiar shape. It is super¬ 
ficial and its outlines can be readily made out. The animal 
being thrown and the region well disinfected, an incision 25 
centimeters (10 inches) long is made, following its greater axis, 
with the bistoury. The cellular tissue under the skin is iso¬ 
lated and the borders of the plate are defined. With strong 
nippers it is raised and loosened from the muscles underneath, 
isolated and removed. The edges of the skin were brought to¬ 
gether by stitches. The wound was entirely closed in ten days 
almost without any suppuration. The plate measured 25 cen¬ 
timeters in length, 10 in width ; thin at its borders, it is 5 or 10 
millimeters thick in its centre. Under the microscope it shows 
Haversian canal and osteoblasts well formed. It is certainly 
an osteoma and not simple calcification.— {Bull. Soc. Cent.) 
Rupture of the River Due to an Osteoma of a Chon- 
dro-COSTAL Articulation [By M. Remond ].—Ruptures of the 
liver are not rare, but they generally occur on the right and mid¬ 
dle lobes. In this case it was on the left and middle lobes that the 
seat of the haemorrhage existed. The cause of it, however, is 
onb/ problematical. An Arabian horse is found one night dy¬ 
ing in his stall and succumbed before the author had time to 
reach him. Death had taken place without great struggles ; the 
bedding is not disturbed, there had been no colics, and the ani¬ 
mal had eaten his night meal well. At the post-mortem the 
visible mucous membranes seemed pale ; the abdomen contained 
about fifteen litres of uncoagulated blood. The left lobe of the 
liver was only a mass as big as a child’s hand, formed of clots 
of blood and hepatic remains. At its convex border the capsule 
was torn by a rupture measuring 7 or 8 centimeters. The mid¬ 
dle lobe was the seat of subperitoneal hematomas ; it was soft and 
easily torn. The right lobe is entirely bloodless, covered with 
a normal capsule, and seems to have undergone amyloid de¬ 
generation. Its structure is very soft, puffy in consistency and 
gray-yellowish in color. On the seventeenth right rib, at the
