 cluded that neither redtide nor seasonal 

 variations could be held responsible 

 for the fluctuations observed in sizes 

 and occurrence of specimens.

Soil extracts have been widely suc- 

 cessful in promoting the culture of 

 organisms difficult to grow in inorganic 

 media. The active principle in soil 

 extract according to Pringsheim (E. G. 

 Pringsheim, 1936, Das Ratsel der 

 Erdabkochung. Beih. Bot. Centralblatt 

 A55: 101-121) in experiments using 

 Chlorogonium , Polytoma , Polytomella , 

 £ind Chilomonas is am acid- and alkaline- 

 stable organic substance, insoluble in 

 alcohol and ether, adsorbed by charcoal, 

 and destroyed by hydrogen peroxide. 



Gymnodinium splendens was cultured 

 in several media, usually in inorganic 

 media with organic additives. No in- 

 organic additives aided growth. Soil 

 extract promoted growth. The soil ex- 

 tract was made from redistilled water 

 and garden soil, which was autoclaved, 

 decanted after standing overnight, and 

 reautoclaved. Although presumably bac- 

 teria-free, the soil extract was of little 

 or no avail when first prepared; it 

 reached a peak of activity (in promoting 

 growth) in 4-6 weeks and declined in 

 activity after about 80 days. Activity 

 of soil extract was not retained by re- 

 autoclaving or by refrigeration at 4° C. 

 Deep freezing at -25° C. preserved ac- 

 tivity for 6 months. Trials of additions 

 of several different amino acids, yeast 

 extract, oak leaf mold extracts, etc., 

 were unsuccessful. 



The only other active principle came 

 from cells of another dinoflagellate, 

 P ro roc ent rum micans , also grown in 

 4 percent soil extract.

"In cultures of the marine dinoflag- 

 ellate Gonyaulax polyedra grown with 

 alternating light and dark periods of 

 12 hours each, at least 85% of all cell 

 divisions which occur in a day take place 

 during a 5-hour period spanning the end 

 of the dark period and the beginning of 

 the light period. A very distinct maxi- 

 nnum in the number of recently divided 

 cells occurs at about the time the light 

 period begins. 



"This diurnal periodicity in cell divi- 

 sion is lost after 4 to 6 days in con- 

 tinuous bright light, but will persist for 

 at least 14 days in continuous dim light. 

 The period of approximately 24 hours 

 under constant conditions is only slightly 

 altered by varying light intensity and 

 tennperature, both of which factors are 

 known to affect markedly the generation 

 time. The tinne at which cell division 

 occurs is therefore postulated to be 

 controlled by some sort of rhythmic 

 or clock mechanism. 



"Similarities between the cell divi- 

 sion rhythm and the endogenous rhythm 

 of luminescence in this organism are 

 discussed. The occurrence of a glow, 

 or steady light emission of low intensity, 

 at about the time of cell division, is 

 described, and it is suggested that this 

 glow may result from cellular changes 

 accompanying certain stages of cell 

 division." [p. 217.]
