The ordinates represent percentage development and the abscissae the time of immersion in the salt solution before fertilization. It is evident from the chart that the cations can be arranged in the following toxicity series. Li > Na > Mg, Ca > K > Rb > Cs. Figures 2 and 3 show graphically the results of the average of nine experiments in which the divisions per egg corrected by the control is plotted against the time in the electrolyte. In Fig. 2 the eggs were allowed to develop for one and one-half hours after insemination and in Fig. 3 three hours, before being fixed in form- alin and Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
