from twenty to fifty head. In two instances, more than two 
were found to be diseased in a herd ; in one case, three were 
killed; in another, five were slaughtered. In Westchester 
County, out of about 10,000 examined, in the neighborhood of 
eighty-five head were slaughtered, but there were more 
errors in diagnosis made here than in Orange County ; a num¬ 
ber of mistakes, six or eight, perhaps, having been made. In 
Orange County, out of thirty-five cows killed, only one was 
not tuberculous, and the diagnosis in her case was not posi¬ 
tive, as before she was killed it was suspected that she might 
be suffering from pneumonia, which proved to be the case. 
The value of dairy inspection was better demonstrated in 
Westchester County, as here several herds were fouud badly 
infected with tuberculosis. In one instance it was found 
necessary to destroy an entire herd, not counting a few that 
died before final arrangements were made for killing the re¬ 
mainder (eleven head having been killed in December); fifty- 
two animals, all told, were slaughtered on two different oc¬ 
casions, one bull tuberculous, thirty-nine cows, all more or 
less tuberculous, except one, four two-year-old and eight 
yearling heifers, fifty per cent, of them being tuberculous. 
This herd had formerly consisted of fine Jerseys, but a num¬ 
ber of so-called natives had been bought during the past few 
years to take the place of cows that died. The milk from this 
farm was being sold in New York City as very fine Jersey 
milk at the high price of twelve cents a quart. 
In another lot of cattle, consisting of twenty-four head, 
the milk being peddled in the neighborhood where they were 
kept, six cows were killed and found to be tuberculous, a 
total of twenty-five per cent. In another local milkman’s 
herd, consisting of fifteen animals, five were slaughtered, and 
proved to be tuberculous by post-mortem examination, mak¬ 
ing thirty-three and one third per cent, of the number on the 
farm. 
The other animals killed in Westchester County were all 
scattering cases, only one, two, or three from a farm, and a 
few of these which were killed on suspicion proved to be 
errors in diagnosis. Possible errors of diagnosis were found
