According- to the label, the dry points were prepared by the manu- 
facturer October 31. 190:2. aiul were planted November 29. 1902. : 
The olvcerinated cirus was not dated. It was counted December | 
1. 1902. 
The following organisms resembling the pyogenic cocci were isolated: 
Coccus Xo. -26 . — This staphylococcus was one of S.74S colonies which grew on our ! 
agar plates, planted from a dry point of manufacturer Xo. 9. 1 
The staphylococcus stains by Gram’s method; does not produce indol in a 24-hour 
bouillon culture; is slightly acid in litmus milk; does not liquen^ gelatine; bouillon 
cloudy, with yellow precipitate; on agar, an orange moist glistening, growth; on 
potato, heavy yellow growth; in glucose bouillon, no fermentation, growth ail J 
through; in lactose bouillon, no fermentation, growth all through. 
Coccvji Xo. 27 . — This staphylococcus was one of 8,748 colonies which grew on our 
agar plates, planted from a dry point of manufacturer 27o. 9. 
The staphylococcus stains by Gram’s method; does not produce indol in a 24-hour 
bouillon culture; slight acid production in litmus milk; does not liquefy gelatine: in 
bouillon, heavy white pelhcle, with precipitate; on agar, an orange-yellow moist 
glistening growth; on potato, a yellowish granular growth; no fermentation, cloudy 
all through, in glucose bouillon; and in lactose bouillon there is no fermentation, 
but the bouillon is cloudy all through. 
Coccus Xo. -28 . — This staphylococcus was one of 12,972 colonies which grew on our 
agar plates, planted from a dry point of manufacturer 2s o. 9. 
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 a 
precipitate of casein; rapidly liquefies gelatine; in bouillon, cloudy with yellow 
precipitate; on agar, an orange moist ghstening growth; on potato, a heavy yellow 
growth; in glucose bouillon, no fermentation, but cloudy all through: in lactose 
bouillon, no fermentation, cloudy all through. 
Coccus Xo. 29 . — This staphylococcus was one of 43 colonies which grew on our agar 
plates, planted from a tube of manufacturer 2s o. 9. 
The staphylococcus stains by Gram’s method; does not produce indol in a 24-hour 
bouillon culture; in htmus milk, a strong acid production, coagulation, and precipi- 
tate of casein; very rapidly liquefies gelatine; bouillon shghtly cloudy with yellow 
precipitate; on agar, an orange-yellow moist gh.stening growth; on potato, yellowish 
slowly spreading growth; in glucose bouillon, no fermentation, but growth all* 
through; in lactose bouillon, no fermentation, but growth all through.
