PLEUROPNEUMONIA. 
81 
On the 17th day of February, ill company with Professor 
Law and Dr. Hopkins, I visited the farm of Mr. Joseph Sprague, 
in Kent, Putnam County, whose herd was infected and had been 
in quarantine for some time. The herd consisted of fifty-three 
head, and were sold during the day by the State Commission to 
butchers who had been notified to attend. The animals brought 
an average of $6 per head, which was regarded as a low price. 
Three of the animals were considered too badly diseased for beef, 
and on being killed showed well marked lesions of the disease in 
its different stages. The herd was infected by a cow purchased 
from a dealer named Robinson. 
On February 18, in company with the same gentlemen, I vis¬ 
ited Croton Falls, Westchester County. We found here a gen¬ 
tleman by the name of Butler, who had lost thirty-one animals 
out of a herd of thirty-two by the plague. His remaining cow 
was in quarantine, with no symptoms of the disease manifest. 
On the 15th of June last, Mr. Butler bought seventeen cows of 
Mr. Robinson, the dealer above referred to, and they were deliv¬ 
ered to him on the 17th of the same month. They had been 
pastured all the summer on Hyatt’s Lower Farm,” with a cow 
that had been sick but had recovered. The first animal on But¬ 
ler’s farm sickened on September 16, and soon died. The re¬ 
maining thirty head were either slaughtered for beef or killed 
diseased. 
On February 19, in company with the same gentlemen. I vis¬ 
ited the farm of Mr. Daniel Austin, in Yonkers, Westchester 
County. Originally this gentleman had a herd of twenty-seven 
head, eighteen of which had either died of the plague or had been 
killed for beef in the incipient stages of the disease. Five of the 
animals were killed for beef, and showed no lesions of the dis¬ 
ease. Of the four remaining, two are well marked chronic cases 
— i. e., having portions of eucysted lungs. This herd was infected 
by a cow that had pastured on an infected range called “ Hog 
Hill,” in the town of Yonkers. She wandered into a field near 
Mr. Austin’s place, where she died on the 27th or 28th of July, 
and was not buried for some days after. The disease appeared 
amono; Mr. Austin’s cattle on October 21. The herd of Mr.
