P LEURO-PNEUMONIA. 
had the whole posterior lobe of the left lung consolidated and 
strongly adherent to the costal pleura. The right lung was 
healthy. The pericardium was thickened to half an inch. In both 
lungs of the second cow were found a number of small isolated 
spots of the characteristic lesions of the disease, the largest being 
about the size of u double list. Their borders were well defined, 
and the intermediate portions of the lung tissue appeared per¬ 
fectly healthy to the naked eye. On February 16th, at Twentieth 
street and Fourth avenue, I found three cows which had been ex¬ 
posed to infection and were in quarantine. They appeared healthy, 
and one had just been sold to a butcher named McEvoy. 
In Fremont, at the stable of Mr. Bohle, I found two cows, 
one of which had been put into an infected stable on Christmas. 
Her temperature was 101 degrees, Fahrenheit, and she was breath¬ 
ing at the rate of thirty respirations per minute. The other ani¬ 
mal was a Jersey cow. Both animals had been ordered slaugh¬ 
tered as soon as they could be got ready for the butcher. A Mr. 
Cannons, a neighbor, had had some trouble with his herd, but 
they were quarantined and seemed to be doing well. The infec¬ 
tion to this herd of Mr. Bohle’s was communicated by a cow that 
was pastured with ten others on a common lot. She developed 
contagious pleuro-pneumonia, and was killed in the month of Au¬ 
gust. Three months and nineteen days thereafter the second 
animal was attacked, and sent to the offal dock, where she was 
slaughtered. At the end of three weeks a third, and at the end 
of four weeks a fourth animal was taken sick and both were 
slaughtered. The first one of these animals belonged to Mr. 
B. Jorkman, the other three to Mr. Bohle, who, as has been be¬ 
fore stated, bought a fresh cow on Christmas and put her in with 
one remaining from his original herd. This was in direct viola¬ 
tion of the law and his instructions. She is now diseased and 
has been ordered to be killed. These ten animals were strictly 
isolated as soon as the first cow was killed, and no other infection 
was then possible. Two of them have since been fattened and 
sent to the butcher in a healthy condition. The remainder, with 
the exception of those belonging to Mr. Bohle, are still free from 
disease.
