GENERAL REMARKS UPON THE ABOVE.
The milks contained an enormous number of bacteria, far in excess of what should be
found in good clean milk.
Organisms derived from manure were present in "Q," "T," and possibly in all but
"R" and "S," but in much smaller numbers.
All except "S" and "T" contained an excessive amount of "dirt" the most being in "P."
Pus cells were formed in 3 out of the 5. The significance of this is not absolutely
certain, but in all probability it means that in cows of all the herds supplying the milk in
which pus cells were found, there were some suffering from a more or less inflammatory
condition of the udder. Taking milk from known healthy cows we do not find such cells,
nor were they found in "P" and "R."
