II. On the change of potential of a voltaic couple by varia­tion of strength of its liquid

Abstract

Having found a thermo-electric pile (see ‘ Birmingham Phil. Soc. Proc.,’ vol. 4, p. 130) convenient in detecting and measuring small changes of voltaic potential (' Roy. Soc. Proc.,’ May 3rd, 1888), I have taken advantage of that circumstance to measure by the method of balance the above phenomenon in various liquids.
