INFECTIOUS PLEURO-PNEUMONIA.

If the wound is deep and lacerated, the parts are to be carefully exor¬ 
cised before the caustic is applied. 
In the lower animals it is difficult to discover the little scratches 
that are made by the teeth, then the hair should be very soon clipped, 
and the caustic applied. When a dog has been bitten by a mad animal 
it is better to kill him right off, so as not to give him the chance of 
becoming rabid. 
AN OUTBREAK OF INFECTIOUS PLEURA-PNEUMONIA 
AMONG CATTLE, AT CLINTON, N. J. 
By C. B. Michener, D. V. S., Carversville, Pa. 
On August 16th, 1877, I was requested, by A. S. Leatherman, to 
visit some cows, near Clinton, N. J., the property of J. C. Cramer, which 
were suffering from malignant pleuro-pneumonia. Upon inquiry, I 
elicited the following facts : 
That in the latter part of June or first of July, Mr. Cramer bought 
a cow from a car-load which were sold in his neighborhood, and which 
came from Ohio, by rail, to New York City ; from which place she was 
shipped to Clinton. This cow soon sickened and died; and, although 
she was not autopsied, it was the opinion of the gentleman who treated 
her, that she died from pleuro-pneumonia. At the time I was called to 
see the cattle, -Aug. 16th, four cows, which had been on the farm for 
some time, were affected. 
Had no difficulty in diagnosing the disease as malignant pleuro¬ 
pneumonia, and one of the animals being in the last stages of the dis¬ 
ease, the owner was induced to let us destroy her for the purpose of 
holding a post-mortem examination. 
On opening the thorax we discovered about one gallon of serum, 
in which floated large masses of yellow plastic lymph. 
The lungs were fastened to the pleura-costalis, diaphragm and 
heart, by large deposits of this plastic lymph. After severing these 
“ false membranes,” and attempting to lift the lungs out of the cavity of 
the thorax, we noted that they were unusually heavy, and, upon weigh¬ 
ing them, found that the weight was forty-two (42) pounds—-they sank 
in water, and exhibited the dirty grey mottled color peculiar to this dis¬ 
ease. The lung substance was firm, and the exterior was rough and 
thickened.
