The author exhibited some pieces of apparatus devised in connection with his work on the atomic weight of tin, and also a quantity of pure silver prepared by electrolysis of the pure silver of Stas in strong nitric acid solution. The method of electrolysis was essentially that of Abrahall as modified by Richards. By using a strong acid solution containing fifteen per cent of silver and a battery consisting of sixteen gravity cells the silver was obtained in large crystals and no peroxide was formed at the positive pole. Separate experiments showed that silver deposited under these conditions, from a solution to which copper had been added, contained no trace of the latter metal.
