a day or two to get the material and make the necessary arrange¬ 
ments, and two or three days longer for the men who were clean¬ 
ing the cows to learn the difference between washing the udders 
and wiping them with a damp cloth, so that it was the nth of De¬ 
cember before the new method was put into operation completely. 
A few days later the manager reported no additional cases of the 
udder trouble had been discoverd for a day or two. The effect 
upon the bacterial count may be seen by examining the table given 
below. The samples for examination were all taken from the 
general stock after the milk had been delivered in the city.

externally, with the exception of one cow. The skin, especially 
at the base of the teats and over the teats, was soft and pliable. 
The udders were also improved internally, as the number of cows 
producing milk containing flakes had decreased very consider¬
