Table V. — Samples Containing More Than 10C0 Germs per Cubic 



Centimeter. 



Per ct. of all samples above limit, 12. 

 Maximum observed germ content per cc, 16,610. 



The maximum content here given, 16,610, may not be the high- 

 est actually present among the more than 1,200 samples, since 

 there were four samples from the herd of 1900-02 and two from 

 the herd of 1910-11 where the plates were not counted on ac- 

 count of the large number of colonies present. Three of the 

 four earlier samples were from a single cow and the two later 

 samples were obtained on the same day from another cow.
