Theoretical Aspects and Conclusions. 
The Components of the Growth-curve. 
A growth-curve has been constructed (Curve 6) to simulate the experi- 
mental results, and to show, by analysis, the lines along which further work 
might be attempted. 
Two special assumptions will be made of which no accurate proof 
exists, viz., that — 
(a) The depression of the stopping-point is proportional, in some kind 
of progression, to the amount of 1 x' which is present in the cell at the com- 
mencement of the experiment.
