Contagion Through Infected Buildings. 29 



and some July 3d of Patrick McOabe, dealer. In both 

 cases the fresh cows came from the country and went to 

 the stables, with our permits, furnished after examination. 

 Aug. 19th four cows were found to have the lung plague 

 and were slaughtered. 



Patrick Greene, West Farms, New York Co., took his 

 present place in April, and stocked it with 32 fresh cows. 

 About May 1st sickness appeared in his herd and then 

 for the first time he learned that his predecessor had 

 lost heavily during the past year. In company with Dr. 

 Hopkins I visited his place May 14th and found seven

 appeared.

 cows was found to be affected with lung fever, and was 

 killed in conseqiience. The only appreciable source of 

 contagion was the manure, which had been drawn from 

 infected city stables, and spread on a lot where these 

 cows were turned out on fine days for exercise. In spite 

 of the plowing under of the manure as soon as the frost 

 would allow, three more of her cattle have sickened, and 

 had to be killed May 12th. As further evidence of the con-
