The variability in sensitiveness of the same organism 

 at different tiiiies was most disturbing. " Material 

 which to-day is strikingly chemotactic or phototactic, 

 may be to-morrow unusable. Especially striking and 

 perplexing was the behavior of tipirillitin iiiulnlit, this 

 classical object for chemotaxis and osmotaxis, with 

 uhich Pfeffer made his celebrated investigations, and 

 with which in former years I confirmed the experiments

Plasmolysis was either definitely established or rvn- 

 di n ri extremely presumptive (smaller forms) for lykinds 

 nt !>;uUii;i. The concentration which induced it varied 

 in IMO-I cases from 0.5 to 5 per cent. In a few cases the 

 It -a->t concentration which would induce plasmolysis was 

 nt determined. Generally strengths of I to 2 percent 

 -'"hum chloride were sufficient. "Die untere Grenze 

 ist I'lir alle Bacterien bei I per cent oder 0.75 per 

 cent NaCl."
