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

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

 of temperature (increase makes positive animals negative). KC1 ai d Na 

 CI produce positive changes, Mg Ch or Mg SO* act antagonistically. Want 

 of definite orientation through CaCb. Hypotonic solutions negativate, 

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

 Membrane. Science N. S. Vol. 36 p. 637—639. [Single salt solutions 

 render membrane permeable, inhibited by balanced solution (e. g. : Na 

 CI CaCl). Acids also increase permeability (action on proteins) as well 

 as alcohols (action on lipoids). Membrane a lipoid-protein mosaic. Re- 

 versibility.] 7.55

 ture. Biol. Ceutralbl. Bd. 33 p. 150—170. - Med. Rec. N. V. Vol. S3 

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

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

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

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

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