bouillon culture; no change in litmus milk; does not liquefy gelatine; bouillon cloudy ; 
with white precipitate; on agar, whitish transparent, slightly granular, scanty growth; J 
on potato, brownish white granular growth; in glucose bouillon, no fermentation, i 
growth at bend of tube; in lactose bouillon, no fermentation, growth at bend of tube.

plates planted from a tube of manufacturer Xo. 7. ; 
The staphylococcus stains by Gram’s method; does not produce indol in a 24-hour I 
bouillon culture; no change in litmus milk; hquefies gelatine; bouillon cloudy, white |
