NOLTE—SALIVARY ORGANISMS AND AIR POLLUTION 
From the above table it is evident that all but one of the 
coccus forms in series (A) produced acid in lactose and saccha- 
rose broths, and acid and consequent clotting in milk. Тһе 
one exception was probably an air coccus.

In series (B), 32 out of the 36 cocci reacted positively through- 
out on the three differential media. Тһе remainder were positive 
with saccharose, but negative with lactose and milk, agreeing 
in this respect with the two air cocci to which reference has 
been made.
