on potato, a scant yellowish growth; in glucose bouillon, no fermentation, growth 
at bend of tube; in lactose bouillon, no fermentation, growth at bend of tube. 
Coccus No. 3 . — This staphylococcus was one of 2 colonies which grew on our agar 
plates planted from a tube of glycerinated virus of manufacturer No. 1. 
The staphylococcus stains by Gram’s method; does not produce indol in a 24-hour 
bouillon culture; in litmus milk, a slight alkaline production; does not liquefy gela- 
tine; bouillon is clear, some w^hite precipitate; on agar, a heavy, glistening pink pig- 
ment growth; on potato, very scanty pink growth; in glucose bouillon, no fermen- 
tation, slight growth at bend of tube; in lactose bouillon, no fermentation, slight 
growth at bend of tube. 
Coccus No. 4 . — This staphylococcus was one of 9 colonies which grew' on our agar 
plates planted from a tube of glycerinated virus of manufacturer No. 1. 
The staphylococcus stains by Gram’s method; does not produce indol in a 24-hour 
bouillon culture; in litmus milk, no change, but a white precipitate; does not liquefy 
gelatine; in bouillon, clear, white precipitate; on agar, a scanty white, glistening 
growth; on potato, very scanty white growth; in glucose bouillon, no fermentation, 
slight growth at bend of tube; in lactose bouillon, no fermentation, slight growth at 
bend of tube.

The dry points were labeled to be good until December 7, 1902, and 
were planted for study November 8, 1902. 
The glycerinated lymph was labeled good until December 17, 1902, 
and was planted November 25, 1902. 
The following organisms resembling the pyogenic cocci were 
isolated : 
Coccus No. 5 . — This staphylococcus was one of 8,702 colonies which grew on our 
agar plates planted from a dry point of manufacturer No. 3. The staphylococcus 
does not stain by Gram’s method; does not produce indol in a 24-hour bouillon cul- 
ture; in litmus milk, slightly acid production; does not liquefy gelatine; bouillon 
very cloudy, white pellicle, and precipitation; on agar, grayish- white, shiny, moist 
growth; on potato, heavy yellowish-white growth all over potato; in glucose bouil- 
lon, slight fermentation, cloudy all through; in lactose bouillon, slight fermentation, 
cloudy all through. 
Coccus No. 6 . — This staphylococcus was one of 12,923 colonies which grew on our 
agar plates planted from a dry point of manufacturer No. 3. The staphylococcus 
stains by Gram’s method; 4oes not produce indol in a 24-hour bouillon culture; 
slight acid produced in litmus milk ; liquefies gelatine very slowly ; bouillon is slightly ^ 
cloudy, Avith some white precipitation; on agar, a grayish-white, shiny, moist growth;
