Of wlmt importance this meeting will be we are unable to say, 
as, with the exception of the notice that we believe the secre¬ 
tary has taken the liberty to issue on his own responsibility, we 
are not aware that the officers of the association have given a 
thought to the meeting, and perhaps to the association, since the 
last reunion at Cincinnati. 
If the meeting of the U. S. Y. M. Ass., however, fails to be 
provided with enough interesting material to justify a trip to 
Boston, there is ample provision made for a well-rewarded excur¬

meeting, which takes place on the evening preceding that of the 
U. S. V. M. Ass., and that will give us an opportunity to assist 
in the work done by this young but active association. 
SPORADIC PNEUMONIA AND CONTAGIOUS PLEURO-PNEUMONIA. 
The correct diagnosis of these two diseases is a question that 
has no doubt puzzled many veterinarians, and which has in many 
instances given rise to serious thoughts as to the propriety of ap¬ 
plying severe sanitary measures or to leave an animal or a herd

Even to-day veterinary opinions are divided on the subject, 
and to try to assist in deciding the question, Messrs. Coulon and 
Olivier have prepared a long - paper on this subject, which was 
presented to the Societe Centrale de Medecine Veterinaire of 
Paris, and ordered to be printed in the minutes. 
This has appeared to us of sufficient interest and importance 
to justify its publication in our pages. We have left out of it 
only the symptomology and the lesions of pleuro-pneumonia 
proper, as those have been published over and over again, and 
have satisfied ourselves in translating sporadic pneumonia, with 
its history as it is given in the original paper, with the conclu¬ 
sions by which, according to the authors, a correct differential 
diagnosis can be made. We hope that the reproduction will be
