The following organism;? resembling the pyogenic cocci were 
isolated; 
Coccus Xo. 11 . — This staphylococcus was one of 475 colonies which grew on oui* 
agar plates planted from a dry point of manufacturer Xo. 4. 
The staphylococcus stains by Gram’s method; does not produce indol in a 24-hour 
bouillon culture; strong acid production in litmus milk; rapidly liquifies gelatine; 
bouillon is cloudy, with some precipitate; on agar there is a whitish-yellow, moist, 
shiny growth; on potato, a yellow growth, spreading slowly; in glucose bouillon, no 
fermentation, but cloudy all through; in lactose bouillon, no fermentation, cloudy all 
through. 
Coccus Xo. 12 . — This staphylococcus was one of 475 colonies which grew on our 
agar plates planted from a dry point of manufacturer Xo. 4. 
The staphylococcus stains by Gram's method; does not produce indol in a 24-hour 
bouillon culture; in htmus milk, acid production, coagulation and casein precipitate; 
bouillon is slightly cloudy, white precipitate; on agar, whitish gray, moist, glisten- 
ing growth; on potato, white granular growth; in glucose bouillon, no fermentation, 
growth all through; in lactose bouillon, no fermentation, growth all through. 
Coccus Xo. 13 . — This staphylococcus was one of 11 colonies which grew on our 
agar plates planted from a tube of manufacturer ZSTo. 4. 
The staphylococcus stains by Gram’s method; does not produce indol in a 24-hour 
bouillon culture; no change in htmus milk; does not liquefy gelatine; bouiUon 
slightly clouded, yellow precipitate; on agar, growth transparent, thin layer, no pig- 
mentation; on potato, scanty yellow groTvth ; in glucose bouillon, no fermentation, 
slight growth at bend of tube; in lactose bouihon, no fermentation, shght growth at 
bend of tube.

ing growth; on potato, no growth; in glucose bouillon, no fermentation, but growth 
aU through; in lactose bouillon, no fermentation, but growth all through.
