��* Sir Charles VVheatstone, in his paper on New Instruments and Processes, Phil. Trans., 1843, brought this arrangement into public notice, with due acknowledgment of the original inventor, Mr. S. Hunter Christie, who had described it in his paper on Induced Currents, Phil. Trans., 1833, under the name of a Differential Arrange ment. See the remarks of Mr. Latimer Clark in the Society of Telegraph Engineers, May 8, 1872.
