The above evidence, if it stood alone, might be regarded as 

 indicating the truth of the statements which have been made con- 

 cerning the influence of the various factors mentioned. But when 

 the group of cows which gave low cell counts is examined, it is 

 seen that this includes one cow which had had udder troubles 

 recently and still had a hard lump in her udder (Chloe B.), one 

 cow which had aborted recently (Ruth F. B. B.), and one cow 

 eleven years old (Dotshome Carey). Moreover all but two cows 

 in the herd gave individual tests higher than 500,000 cells per cubic 

 centimeter, and it is probable that these two animals would have 

 given higher counts also if more tests of their milk had been made. 

 Thirteen of the 25 cows gave individual tests higher than 1,000,000 

 cells per cubic centimeter. This makes it highly probable that
