A RARE CASE OF TUBERCULOSIS IN THE HORSE. 
By Prof. G. P. Piaua, Milano. 
From this case the author comes to the following conclusions : 
1. In tuberculosis of horses, the bacilli have the same char¬ 
acters as m tuberculosis of other animals, as far as form, dimen¬ 
sions as their way of action with the various reachtives. 2. But 
the tubercles of horses have characters which distinguish them 
from those of other animals. For instance, the caseification is 
missing, or at least very rare ; they are very vascular, even in 
the most central parts; they contain numerous large (giant) 
cells. 3. All these peculiarities are independent of the special 
propei ties of the bacilla ; a rabbit inoculated with equine tuber¬ 
culous matter has contracted tuberculosis, which presented 
all the characters of this disease in the rabbit .—Inter Cong of

OESOPHAGEAL JABOT IN A COLT. 
M. A. Labat. 
This case is interesting from the double abnomaly which gave 
use to it, The subject is aged seven months. ' He has always 
presented a difficulty in swallowing, and at three months devel¬ 
oped a tumor on the right side of the neck. This increased 
rapidly, and manifested itself when, and immediately after the 
colt had been sucking. At other times the neck is normal on 
both sides. The condition increased as the animal grew older, 
the tumor becoming very large, extending beyond half of the 
neck and giving rise to repeated severe disturbances of digestion. 
The condition increased in severity and one day he was found dead. 
At the post-mortem it was found that the oesophageal dila¬ 
tation, which was displaced on the right side, was enormous and 
extended into the thoracig cavity as far as the base of the heart. 
It seemed to be divided in two portions by a semi-contraction, 
which is seen at a point where was the tracheal bifurcation ; it 
twists itself as an S and returns to the left, where beyond it is 
again dilated. By a peculiar arrangement the trachea itself had 
undergone changes in its normal position, its posterior face being- 
twisted to be related to the jabot on the right side._ Rev. Veter.
