Since my last communication to the Society on this subject, I have continued my experimental investigation of the proposed law which limited the direct action of the voltaic current to the solvent, in solutions of primary combinations of elementary bodies in the more important solvents. All my farther researches have confirmed the rule in regard to aqueous solutions; and I feel now fully convinced of its truth, although, in the mean time, I have had occasion to see a different view advocated by some other experimenters, to whose opinions I shall afterwards advert. Neither have I seen any grounds for altering my views in regard to alcoholic solutions. In regard to ether, some experiments which I shall afterwards mention, have satisfied me that it would be improper at present to include that solvent in any general rule.
