Fig. 2. Ordinates represent logarithms of the number of particles not yet 

 ingested. Abscissae represent time in hours since the beginning of the experiment. 

 Points from three separate but simultaneous experiments are plotted for each 



curve. Experimental ratio " ^ is 0.3; theoretical ratio is 0.58. The fact that 



K^Tfi is not constant causes this ratio to increase as predicted.
