The following organisms resemlDling the pyogenic cocci were isolated: 
Coccus Xo. 32 . — This staphylococcus was one of 283 colonies which grew on our 
agar plates, planted from a dry point of manufacturer Xo. 11. 
The staphylococcus stauis by Gram’s method; does not produce indol in a 24-hour 
bouillon culture; in litmus milk there is a slight acid production, coagulation, and a 
jDreci pirate of casein; rapidly liquefies gelatine; in bouillon, slightly cloudy, with 
some yellow precipitate; on agar, orange yellow granular growth; on potato, yellow 
granular spreading growth; in glucose bouillon, no fermentation, growth at bend of 
tube; in lactose bouillon, no fermentation, growth all through tube. 
Coccus Xo. 33 . — This staphylococcus was one of 333 colonies which grew on our 
agar plates, j)lanted from a dry point of manufacturer Xo. 11. 
The staphylococcus stains by Gram’s method; does not produce indol in a 24-hour 
bouillon culture; strong acid production in litmus milk; does not liquefy gelatine; in 
bouillon, shghtly cloudy, with some white precipitate; on agar, a white shiny growth; 
on potato, nearly inyisible white growth; in glucose bouillon, no fermentation, slight 
growth at bend of tube; in lactose bouillon, slight growth at bend of tube. 
Coccus Xo. 34 - — This staphylococcus was one of 24,360 colonies which grew on our 
agar plates, planted from a dry point of manufacturer Xo. 11. 
The staphylococcus stains by Gram’s method; does not produce indol in a 24-hour 
bouillon culture; in litmus milk there is a strong acid production, coagulation, and 
precipitate of casein; slowly liquefies gelatine; bouillon is cloudy, with heavy white 
precipitate; on agar, a whitish yellow, shiny moist growth; on potato, yellow growth 
with white border; in glucose bouillon, no fermentation, growth all through tube; in 
lactose bouillon, no fermentation, growth all through.
