1884 Philos. Trans. (Royal Soc.) 175 ii. 447 The manner in which the Clark cells have borne the tests applied to them justifies the hope that they may be found generally available as standards of E.M.F.

1943 Gloss. Terms Electr. Engin. (B.S.I.) 96 Clark cell, a standard cell having electrodes of mercury and zinc amalgam in an electrolyte of zinc sulphate with mercurous sulphate as a depolariser. (The e.m.f. of a Clark cell is 1·433 volts at 15° C.).
