All told, this station has been concerned
In the test of 935 milch cows, more than

Ot the total list, 1S5 head, or 10 $40 per

Three hundred and ninety head have
been examined during the year ending on

IHE PREPARATION OF TUBERCULN.-
The high prices demanded for the imDort-
ed product and the difficulties experienced
In securing the necessary supply led to at
tempts to prepare it at Newark. The bac-
terlolOgist can now produce it at the rate
OF 2OO doses per week. The supply on
hand at present is sufficient for the test of
more than 500 cows This homemade
product responds promptly to all of the
meteorological and biological tests pro-
posed by Koch. In barn practice it has
