The "Generic Characters in the Coccaceae" is the title of 

 an article in Science, May 24, 1906. They say "The best basis 

 for a natural classification is the statistical study of a large series 

 of individuals, which will disclose the points about which the 

 largest number of races are grouped, which are presumably the 

 type centers around which the organisms vary." Six generic 

 groups are established : Streptococus, Aurococcus n. g., Diplo- 

 coccus, Albococcus n. g. — these forming the family Para- 

 coccaceae (parasitic forms) ; and Micrococcus, Sarcina, Rhodo- 

 coccus n. g. — forming the Metacoccaceae (saprophytic forms).

An abstract of "Movements of Certain Bacteria in Soils," 

 published in Science, May 24, 1907, indicates that in sterilized 

 favorable soils saturated with water, Bacillus ochraceus, Pseu- 

 domonas radicicola, and the paracolon organism grow with equal 

 speed, progressing about one inch in 48 hours. In soils barely 

 moist Pseudomonas radicicola progresses at the rate of one inch 

 in y2. hours, while the two other forms are reduced to a rate of 

 about one inch in 8 days.
