pleuro-pneumonia prevailed in Baltimore, and that active measures 
were taken to exterminate it. If, however, it exists in the Western 
States we fear that it will be scattered far and wide. 
If the States where the disease now exists will exterminate it, and 
Congress enact a stringent quarantine law, the malady which has already 
cost England hundreds of millions of dollars, will be prevented from 
gaining a foothold on our shores.— Fro?n the PlougJwian, Boston. 
RECOVERY OF CATTLE AFFECTED WITH CON¬ 
TAGIOUS PLEURO-PNEUMONIA. 
By E. T. Thayer, M. D. V. S., 
Member of the Massachusetts Board of Commissioners on Contagious Diseases 
among Cattle. 
In the January number of the Review is an article entitled “An 
Outbreak of Infectious Pleuro-pneumonia among Cattle at Clinton, 
N. J.,” by C. B. Michener, D. V. S. 
It is gratifying to know that the authorities are taken active mea- 
suies to check the spread of the disease. In the eighth paragraph is 
the following: ‘‘Out of J. C. Cramer’s herd of forty-two (42) cows 
twelve (12) died of the disease in question, five (5) got well under treat¬ 
ment,” etc.; and in a subsequent paragraph he says “they recovered .” 
Now what we wish to learn is, what is meant by recovery; is it 
that the lungs are restored to their normal condition, that no part is de¬ 
stroyed? If it proves to be so, it will be entirely different from the 
results in this State. During the prevalence of the malady in Massa¬ 
chusetts, from 1859 to 1866, many opportunities occurred to examine 
the lungs of animals, both in the acute and chronic stages, some of 
which had been kept eighteen months after supposed recovery. In 
every instance there were found cysts containing lung tissue, or in a 
more advanced stage, pus, and still later, cheesy matter. An incident 
occurred in our investigations bearing upon the subject of recovery, 
which is worth relating. 
The legislature of 1863, through the opposition of certain per¬ 
sons, refused to appropriate a sufficient sum of money for the Cattle 
Commissioners to perform their duties, consequently they resigned. 
According to the statute it was left in the hands of the municipal 
authorities of the towns and cities.
