8 BOARD OF AGRICULTURE. 



In March, Mr. Whiting purchased the three cows of a dealer ; 

 the one first sick came from the north part of Waltham, the 

 market day previous to his purchasing them. By the statement 

 of Mr. Whiting, she was taken sick about April 1st, but accord- 

 ing to that of his hired man, after the 21st, and was very sick 

 for some time, but gradually recovered her appetite, and on our 

 first visit gave seven quarts of milk per day. She was thin of 

 flesh, and gave evidence of having suffered severely. 



On the 13th of June, another was taken sick, which died 

 the 8d of July. On the 4th, an examination was made, which 

 disclosed the right lung wholly consolidated, and weighing 

 twenty-six pounds. The thorax contained at least three gallons 

 of serum ; a thick coat of lymph intervened between the pulmo- 

 nary and costal pleura. 



On the 22d of the same month, the third cow was taken sick, 

 and ■ on the 24th she presented the usual symptoms of pleuro- 

 pneumonia. Both of those that survived were kept until the 

 22d of November, when they were slaughtered ; a description of 

 them is given in the report relating to experiments, which have 

 been conducted during the past year. 



As the pastures of Mr. Whiting are adjoining those on which 

 a large number of cattle are kept, and his cattle remained there 

 until one or more of them became sick, when they were secured 

 in the barn, considerable apprehension existed that the disease 

 would spread; consequently, directions were given that the 

 cattle in the immediate vicinity should be isolated, which 

 was done a suitable length of time, when no further sickness 

 appearing, they were released. 



The next case to which our attention was called was a cow, 

 belonging to Mrs. Carey, of Nahant. She was purchased of a 

 dealer in Lexington in June, and had been kept at Nahant until 

 the time she died, October 5th. The lungs were sent for exami- 

 nation, and it was estimated that the diseased one would weigh 

 more than forty pounds. It presented the usual characteristics 

 of the disease in question. 



It is proper to state that this animal was kept in the same 

 enclosure with another until she became sick, when she was 

 shut up by herself in a stable, and as it was impossible to ascer- 

 tain with certainty whether the other cattle in town had been 

 exposed, or, if any, how many, they were all prohibited from
