butcher. Post-mortem: All the organs are healthy except the 
oesophagus, which is much enlarged, but the red striated muscle 
of that canal is continued to the cardia by a very hard enlarge¬ 
ment, elongated from forwards backwards and between the 
superposed muscular layers there is an elongated, whitish, hard 
tumor, as big as the finger and measuring six centimeters in 
length. With the appearance of a lymphosurcoma, the micro¬ 
scopic examination classes it as a ceromyoma.— ( Presse

Total Absence of Teeth in a Dog [Prof. Dechambre ].— 
This was observed in the skull of an English toy terrier, thirteen 
years old, which died with a paralytic stroke. During life the 
buccal cavity has been noticed as being toothless. There was 
on the palatine arch two bucco-nasal fistulae. The skeleton 
showed no trace of teeth nor of alveoli on the superior maxil¬ 
lary. The crest which ordinarily is formed by the insertion of 
the molars did not exist. The branches of the lower maxillary 
were not united and showed no indication of the bony support 
for the incisive arch. There were, however, three small de¬ 
pressions as aborted dental alveoli. The two maxillary halves 
were incomplete and partly atrophied. The animal had lived to 
old age because of the great care he received. His food consisted 
of milk soup and sometimes of crushed cooked liver mixed with 
soft bread.— {Bull, de la Soc. Cent.) 
Rupture of the Primitive Aorta [A. Esclanze, Army 
Veterinarian]. —Mare, of seventeen years, jumps a bar in a 
menage , gallops for some fifty metres, staggers, falls and dies in 
a few seconds. Internal hemorrhage is the cause of death. At 
the post-mortem, the pericardium is found considerably distended 
by an enormous blood clot which has evidently produced the 
syncopal arrest of the heart. A bloody mass surrounds the base 
of the aortic trunk, and under it is discovered a transversal rup¬ 
ture of the primitive aorta, four or five centimeters long, just 
above its starting origin from the left ventricle.— {Ibid.) 
Fractures of the Base of the Cranium [Major Veteri- 
inarian Berton]. — I. Thoroughbred mare of ten years, nervous 
and difficult to ride, drops suddenly on her hock as the saddle is 
put on her; she partly falls and knocks herself against a wall. 
She lays down motionless for a few moments, has some con-
