Etectro-Chemieal Reactions between Metals in fused Salts.—The present communication contains some results of a furthur study of electrical reactions at high temperatures in fused salts.

The interchanges of electro-chemical position between such metals as platinum and copper and platinum and iron in fusing salts, noticed by the author, led to an investigation as to the effect on the metals of varied intensified temperature in different parts of the same fusing salt.
