RESULTS AND CONCLUSION 



Five sequences of readings were taken at approximately exponentially 

 increasing times. For each sequence of readings, equation (1) in THEORY was 

 used to determine a theoretical curve. The curve took into account the fact that 

 an appreciable time was required to complete a sequence of readings. The nor- 

 malized normality is plotted versus the normalized depth, with time a parameter 

 along the curve. The conductance measurements at a given depth were entered 

 into figure 2 to determine the normality, which was then plotted on the same figure 

 as the theoretical curve (figs. 3-7). The agreement between theoretical predictions 

 and experimental results is good, and it is concluded that the theory is valid, and 

 can be applied to a wide range of similar problems.
