fusions did not exist in that animal, but that, on the contrary, 
dien pleurisy was present, both sides of the chest were always 
lore or less filled with fluid. 
At one of the meetings of the Societe Centrale de Medecine 
Teterincdre , Mr. Barrier presented a paper upon the imperfora- 
on of the posterior mediastinum, and the distinct independence 
f the two pleural sacs. In this paper, which we print to-day, 
le reader will notice some important conclusions, which, while 
ley may be of but little importance from a therapeutical point 
f view, will alter considerably the pathology of the lesions which 
re met in the disease mentioned. A careful consideration of 
le subject will be of use to veterinarians in explaining an error 
t diagnosis which may sometimes occur, and by which unilateral 
leuritic effusions have often been mistaken for inflammation of 
le lungs.

be taken in the premises, and we understand that Dr. Salmon, 
: the Bureau of Animal Industry, has given advice somewhat 
milar to ours. To make assurance of a satisfactory issue in the

7 the college authorities, the opinion of Dr. Michener was applied 
r, and his report has been duly presented. It will be found in the 
•esent number of the Review. The entire herd was found to be 
seased, and were one and all destroyed. The post-mortem exarn- 
ations plainly revealed the tuberculous character of the lesions, 
id confirmed the diagnosis. 
In the presence of the great and widespread excitement which 
-s prevailed in the West on the subject of contagious pleuro- 
leumonia, it is to be regretted that the agricultural press should 
t be more thoroughly informed in respect to the difference 
nch exists between that and tuberculosis disease. Tuberculosis 
not contagious pleuro-pneumonia, and vice versa. 
We were much surprised to find in so intelligent a paper as
