Cultivation of Rhizobes .*■ — Mr. A. Schneider cultivated rhizobes in 
the following way : — Instead of ordinary pepton gelatin he used a culti- 
vation medium of agar made up with a watery extract of Melilotus alba. 
To the extract pepton, pancreatin, and NaCl were added in different 
quantities. The reaction of the medium was acid. The bacteroids of 
M. alba were artificially cultivated by incising a root-tubercle and then 
inoculating the medium from the wound. After 4-5 days white colonies 
of Rhizobium Frankii var. majus were formed. Most of them were 
mobile, and they multiplied both by spores and fission. The mobility 
was greatest in fluid media, and the character of the movements rendered 
the presence of cilia probable. By staining with Hoffmann’s violet a 
cilium at both ends was demonstrated (sometimes two). Spores just 
developing had 3-4 cilia.
