PLEURO-PNEUMONIA IN CATTLE, AS IT HAS 
RECENTLY SHOWN ITSELF IN AMERICA. 
By C. M. Wood, Y.S., Boston, Massachusetts, U.S. 
Early in October, 1859, I learned that Winthrop W. 
Chenery, Esq., one of the merchant princes of this city, and 
a resident in the town of Belmont (seven miles distant), had 
lost a large number of his stock, by a disease which nobody 
appeared to understand. On the 26th of that month, I met 
and spoke to Mr. Chenery upon the subject, when he not 
only corroborated what I had previously heard, but also in¬ 
formed me that he had lost twenty-four head of valuable 
cattle, of various ages, and many of them imported at great 
cost. He likewise stated that one of a yoke of working 
oxen was then sick with the same distemper, and he feared 
it would die. Further, that he still had a number of valua¬ 
ble animals, which he thought would be likely to take the 
disease, and he should be pleased to find some person who 
understood the nature of the malady, so as either to cure it, 
or arrest its further progress. He added that Dr. George 
H. Dadd, of this city, had visited and administered medi¬ 
cine to many of the cattle, but that nearly every case had 
proved fatal. Dr. Dadd said that he had never before seen 
anything of the kind, but from the description he had read 
of it, he believed it to be a disease of Continental Europe, 
called “pleuro-pneumonia,” and that medical treatment was 
of no use whatever, as the disease was always fatal. 
One of my professional brethren, Dr. William Saunders, of 
Salem, in this State, a man of extensive practice amongst 
neat cattle, being present, we agreed to visit the sick ox that 
afternoon. On arriving at the barn, or cowhouse (which 
I will hereafter describe), we found the animal lying in a 
box or pen. He was eight years old, of the Devon breed, 
and exhibited the following symptoms: countenance de¬ 
jected, eyes sunken in their orbits; pulse 70, small and wiry; 
respiration laboured, rumination and appetite lost, bowels 
constipated, breath offensive. He sighed heavily as he lay, 
and when urged to rise gave a loud grunt, and when up 
moved reluctantly and with much apparent difficulty. His
