SEEIES III. 
The following tables give the results of our studies made during the 
winter, November and December, 1902. 
Note especially how vastly superior the glycerinated virus in this 
series is to Series I and II. Eighty-nine capillaiy tubes examined 
averaged only 29 bacteria per tube, whereas in Series II, made in 
April and May, 1902, the average was 1,058, and in Series I, made 
in the winter 1901-2, it was 4,698.

These points were labeled by the manufacturer to be exchanged 
after November 23, 1902, and were counted November 21, 1902. 
The glycerinated lymph was labeled good to December 10, 1902, and 
was counted November 21, 1902. 
The following organisms, some of which resemble the pyogenic 
cocci, were isolated: 
Coccus No. 1 . — This staphylococcus was one of 3 colonies which grew on our agar 
plates planted from a dry point of manufacturer No. 1. 
The staphylococcus does not stain by Gram’s method; does not produce indol in a 
24-hour bouillon culture; no change in litmus milk; does not liquefy gelatine; bou- 
illon is slightly clouded with some white precipitate; on agar, a grayish white moist 
glistening growth; on potato, white growth, slowly spreading; in glucose bouillon, no 
fermentation, growth at bend of tube; in lactose bouillon, no fermentation, growth 
at bend of tube. 
Coccus No. 2 . — This staphylococcus was one of 11 colonies which grew on our agar 
plates planted from a dry point of manufacturer No. 1. 
The staphylococcus does not stain by Gram’s method; does not produce indol in a 
24-hour bouillon culture; no change in litmus milk; does not liquefy gelatine; bou- 
illon is clear, with a yellow precipitate; on agar a lemon yellow, moist, shiny growth;
