GENERAL REMARKS UPON THE ABOVE.
In all cases the number of Bacteria present was so great that by the third day the plates were
liquified, though the dilution used was I in 10,000 (1 c.e. to 10 litres of sterile water). The numbers
given were the counts on the second day at end of 48 hours.
The greatest amount of dirt and of Baoteria was present in "G."
Streptococci were so prevalent in "F" as to suggest some infection of the cows' udder, but no
definite pus cells could be found in the milk.
The only sample containing Bacilli which may be Tubercle is "J." The cows should be examined
or an inoculation test applied to ascertain if they are really Tubercle Bacilli.
"H," "G," and "1" shew presence of fœcal matter; the other two, "F" and "J" are clean.
