To meet point (4) in spite of fact (a) they initiated a program of studies on the stability of the resistance of alloys. In recognition of (c) and (b) they constructed a considerable number of standard resistors of the best lmown construction adjusted as closely as feasible to their " EA unit; " and distributed them internationally and by sale to the public.…”

The present status of the absolu t e measurements on which. all electrical units are based is reported, and tables are included for the convers ion of equatlOns and numerical values from one system to another.
