bifurcated at the level of the third cervical vertebrae. Each head 
has its own atlas and axis, each axis being articulated with the 
third cervical vertebrae. There were two aesophaguses united 
into one single canal at the entrance of the chest, and also two 
tracheas, not united. The nerves, the jugular, and the carotids 
were also double. The cow, though very sick after her delivery, 
made a rapid recovery.— Ibid. 
A TRANSVERSAL PRESENTATION. 
By M. Baulet-Josse. 
A mare presented all the symptoms of a difficult labor. By 
exploration, while standing up, the author observed that the 
neck was widely dilated, and the hand pushed into the matrix 
feels the back of a foetus, 'which seems very large. Another ex¬ 
ploration in the decubital position reveals the same condition. 
Failing to change the presentation and to take hold of any part 
of the foetus to change its position, the mare was destroyed. At 
the post mortem, made the next day, it was found that the fore¬ 
legs, the head and the neck were engaged in the right half of 
the uterus, and the hind legs in the left. The long axis of the 
foetus was perpendicular to that of the mare. 
The conclusions of the author are that: 
First. Presentations by the back alone, with the legs forward, 
are seldom seen, but are incurable. 
Second. Presentations by the four legs are quite frequent, 
but generally followed by recovery.— Ibid. 
A CASE OF OSSIFICATION OF THE TRACHEA FOLLOWING. 
TRACHEOTOMY. 
By M. Benjamin. 
The animal that died from this lesion was a Percheron stal¬ 
lion, six years old. Affected with an acute laryngitis, he had 
been tracheotomized. Relieved by the operation, he made a good 
recovery, the tube remaining in the trachea but a few days.
