on potato, a white, granular, spreading growth; in glucose bouillon, no fermentation, 
slightly cloudy at bend of tube; in lactose bouillon, no fermentation, slightly cloudy 
at bend of tube. 
Coccus Xo. 7 . — This staphylococcus was one of 26,411 colonies which grew on our 
agar plates planted from a dry point of manufacturer Xo. 3. The staphylococcus 
stains by Gram’s method; does not produce indol in a 24-hour bouillon culture; no 
change in litmus milk; rapidly liquefies gelatine; bouillon is clouded with white pre- 
cipitation; on agar there is a white, moist, shiny growth; on potato, a white, granu- 
lar growth, nearly invisible; in glucose bouillon, no fermentation, but growth at 
bend of tube; in lactose bouillon, no fermentation, but growth at bend of tube. 
Coccus Xo. 8 . — This staphylococcus was one of 31,380 colonies which grew on our 
agar plates planted from a dry point of manufacturer Xo. 3. The staphylococcus 
stains by Gram’s method; does not produce indol in a 24-hour bouillon culture; no 
change in litmus milk; liquefies gelatine very slowly; bouillon is slightly cloudy, with 
white precipitation; on agar, a yellowish-white, moist, shiny growth; on potato, 
white, granular growth nearly imdsible; in glucose bouillon, no fermentation, growth 
at bend of tube; in lactose bouillon, no fermentation, growth at bend of tube. 
Coccus Xo. 9 . — This staphylococcus was one of 95 colonies which grew on our agar 
plates planted from a tube of manufacturer Xo. 3. The staphylococcus does not stain 
by Gram’s method; does not produce indol in a 24-hour bouillon culture; strong 
acid production in litmus milk; does not liquefy gelatine; bouillon is verj' cloudy, 
white precipitate; on agar, a grayish- white, moist, shiny, glistening growth; on 
potato, very heavy, white growth all over; in glucose bouillon, fermentation 14 inch, 
growth all through; in lactose bouillon, fermentation three-fourths inch, growth all 
through. 
Coccus Xo. 10 . — This staphylococcus was one of 112 colonies which grew on our 
agar plates planted from a tube of manufacturer Xo. 3. The staphylococcus stains 
by Gram’s method; does not produce indol in a 24-hour bouillon culture; no change 
in litmus milk; does not liquefj' gelatine; in bouillon, clear yellowish pellicle and 
precipitate; on agar, yellow, dry, and granular growth; on potato, very scanty, yel- 
low growth; in glucose bouillon, no fermentation, growth at bend of tube; in lactose 
bouillon, no fermentation, growth at bend of tube.
