repeat well. With the 400-cycle voltage input and the 400-cycle tuned circuit across the null 

 instrument, the potential could be read to six significant figures, with an uncertainty of from 

 3 to 5 in the last place. The extrapolation method described in Appendix A was used in com- 

 puting the potential gradients, but there was no need to use values of 7 and s from a faired 

 curve since they had been measured to a sufficient number of significant figures.
