Fig. 4. Curves showing logarithms of numbers of 3.2/1 and 4.7^ particles not 

 ingested (ordinates) plotted against time (abscissas). Four concentrations (4, 



3, 2, and 1) of the 4.7m particles were used. The best initial K is 0.21 which is 



Je- 

 well satisfied except in one case. Experimental ratio ' ^ = 0.76; theoretical 



ratio is 0.58. This ratio does not increase during the experiment.
