*Very rough approximation, owing to great contamination. 

 tDouble weight, on account of smaller contamination. 

 %A final value at 100, after going to 156, was 533.7. 



SThis same correction for contamination was applied to this value as to the one below it, i. c. 

 two thirds of the percentage change at 18 in the second experiment.
