killed and found diseased,) and they were kept five days in Mr. 

 Olmstead's herd. Two weeks after these oxen left, one of 

 Olmstcad's cows was attacked, and in two or three weeks died. 

 Others followed her until seven out of twenty-two died before 

 April 11, 1860. 



A. A. Ncedham, of New Braintree, took three animals from 

 Stoddard's diseased, into his healthy herd, on January 3d, 1860. 

 The cow from Stoddard's being sick, was returned as unsound, 

 and soon died. 



Twenty-seven days after the arrival of this cow in Needham's 

 herd, one animal was taken sick, and soon others, till eight out 

 of twenty-two died, and many more probably would have met 

 with the same fate had not the herd been slaughtered in April, 

 1860. 



C. P. Huntington bought a cow of Stoddard and took her 

 home, where she soon died. Ten days after, another animal 

 was attacked, and before April 11, 1860, eight out of twenty- 

 two died. 



Aldcn B. "Woodis kept in his healthy herd a pair of sick oxen 

 belonging to Leonard Stoddard. In three weeks Woodis' 

 cattle began to show signs of disease, and he lost four out of 

 twenty-one head before April 11, 1860. Not a herd escaped 

 where one of Leonard Stoddard's sick cattle was introduced. 

 No fatal case of disease occurred in any herd in this vicinity 

 except in tliose into which diseased cattle from Leonard Stod- 

 dard's herd had been introduced. This certainly seems very 

 strong evidence in favor of contagion, and the exemption of 

 many animals is only analogous to what we see in connection 

 with all acknowledged contagious diseases. 



The only case that appears like an exception to every herd 

 having the disease, after receiving a sick animal from Leonard 

 Stoddard, is that of Curtis Stoddard. We have previously 

 stated that the evidence of the communication of the disease to 

 Curtis Stoddard's herd is inconclusive. But it must be remem- 

 bered that seven head of this herd were placed, on November 

 2d, 1859, in Leonard Stoddard's herd, Avith which they were 

 slaughtered in April, 1860. This herd was exposed by con- 

 stantly passing the sick calf which was in a pen by a passage- 

 way through which the cows went to be milked. It was there- 

 fore fair to infer, that as exposure of the herds to sick cattle
