IN a report1 presented some twenty months ago on the values of e, h and e/m, attention was directed to the numerous inconsistencies shown by the experimental data. More recent developments have resolved a number of these inconsistencies, and it now seems possible to reduce all the really precise experimental data in such a way that only one fundamental discrepancy remains. Because of the great amount of experimental material here involved, it is necessary to omit all details in the present brief letter. I wish merely to remark that I am now using for c the value2 2.99776 × 1010 cm./sec., in place of the former 2.99796.
