 elecfrolytes on phototaxis. Journ. exper. Zool. Vol. 13 p. 591—612. [In- 

 hibition of movement by intense light. Influence of parts of spectrum, 

 of température (increase makes positive animais negative). KCl ai d Na 

 Cl produce positive changes, Mg Cb or Mg SCh act antagonistically. Want 

 of detinite orientation through CaCk. Hypotonie solutions negativate, 

 hypertonic positivate. Effects of other chemicals and stains.] 53.5

 p. 553—561. [Cycle of animal life is an antithetic alternation of sexual 

 and asexual générations, of such nature that the albumins are stereo- 

 chemical antithèses: levo-(sexual) and dextrorotary (asexual). Condition 

 reversed in plants. Enzymes show similar relations. Mixture of trypsin 

 and amylopsin attacks asexual générations only. Use in therapy.]
