SECRETARY'S REPORT. 61 



several small solidified iiortions, with some delicate adhesions, but most 

 of the organ was healthy. 



Autopsy 2G. — Killed a heifer 3 years old, which had been sick ten 

 days. The right pleural cavity contained about ten quarts of serum, 

 and a large quantity of lymph. The left lung was mostly consolidated, 

 and adhered to the costal pleura. A small part of the lower portion of 

 the lung was unatiected. — Drs. Thayek and Dadd, April 12, 18 GO. 



Curtis Stoddard, 2d's, Herd. 



This herd is the one into which the Chcnery calves were 

 introduced on their arrival in North Brookficld. The herd 

 passed and repassed the sick Chenery calf in a pen, beside the 

 passage-way through which the cows went twice a day to be 

 milked. Of the three Chenery calves, one died about the 20th 

 of July, 1859, before any thing was known about the disease 

 in this vicinity, and was consequently not examined post 

 mortem. 



Let us now trace the history of the two remaining Chenery 

 calves. As previously stated, they went to Roland F. Doane's, 

 for keeping, immediately after Stoddard's auction, on Novem- 

 ber 2d, 1859. The bull-calf was at West Brookfield cattle-show 

 in the Autumn of 1859, and stood next to a bull belonging to 

 the hospital at Worcester. These two Chenery calves were 

 afterwards slaughtered by the commission in April or May, 

 with the cattle belonging to Mr. Doane. 



Autopsy 27. — The bull-calf, aged eleven months, and wliich stood at 

 West Brookfield last Autumn, beside the hospital bull from Worcester, 

 and near many other cattle, was killed at Roland F. Doane's barn. Here 

 are the records as taken by the secretary of the Cattle Commissioners. 

 " Right lung ; general appearance healthy, but on close examination, 

 distinctly marked spots of exudation were discovered in several places ; 

 mucus membrane of trachea injected ; left lung in a similar condition- 

 The disease was regarded by the surgeons as in the progressive stage." — 

 Drs. Dadd and Thayer, April 13, 1860. 



The evidence here does not seem conclusive of disease — 

 morbid appearances are not distinctly described. This animal 

 left Mr. Chenery'^ diseased herd in June, 1859, and was 

 examined in April, 1860. If contagious, it would probably 

 have been in its advanced, not in its early stage — still, this is
