. A treatise on electrolysis and its applications to therapeutical and surgical treatment in disease . advantages which it is unnecessary to mention in this pi; Such is the brief outline of the physical explanation of the cause of 12 ELECTROLYSIS. setting in action an electrical force, kinetic energy, or electricity as it issimply named and known to the general reader. It is hardly necessary tomake a fuller explanation, but the principle may be better understood byapplying the resulting laws of physics directly to the subject under discus-sion. In the instance of dynamic effect first related, we see the manifesta-tion in electric spark, or light, caused by the effort to reunite the twokinds of electricity which have caused molecular disturbance in energy or force, by whatever name it may be called, which accom-panies the passage of the current in a material substance, may also mani-fest itself in chemical transformations; these may be induced by even veryfeeble currents, and the fluids through which the electricity traverses may ~i f H : ~jV >ss ~~: T\ % l •——-. :.

As yet scientists have not agreed upon a physical basis upon which toexplain the decomposition of chemical compounds by electricity. ASwede, by the name of (rrotthiis, was the first to propose a theory. Hesuggested that the constituent elements of a binary compound, or of acompound acting as such, contained in its natural condition equal amountsof the two kinds of electricity (positive and negative). During the con-dition of combination the two atoms composing the water molecules,one of which was positive and the other negative, neutralized eachother so as to produce a state of electrical equilibrium; for instance,the electro-positive hydrogen was combined with the electro-negativeoxygen; but if an electrical current was exci
