 had the properties of pure potash ; and when it had been 

 saturated with nitric acid it gave no turbidness by mixtura 

 with solution of muriate of barytes : the acid matter ex-

IV, On the Transfer of certain of the constituent Parts of 



Bodies by the Aotion of Electricity. 



Transference of M. Gautherot has stated*, that in a single galvani« 



certain consti- circle of zinc, silver, and water, in an active state, the oxid« 

 tuent parts of . . - , . , ., \ -^r -xt 



bodies by elec- o* zinc formed is attracted by the silver t ; and M. M. 



tricity, Hisingcr and Berzelius detail an account of an experiment, 



in wliich solution of muriate of lime being placed in the 



' positive part of a siphon, electrified by wires from a Voltaic 



. pile, and distilled water in the negative part, lime appeared 



in the distijlcd water. 



These facts rendered it probable, that the saline element* 

 evolved in decompositions by electricity were capable of 

 being transferred from one electrified surface to another, 

 according to their usual order of arrangement; but to de« 

 monstrate this clearly, new researches were wanting. 



I connected one of the cups of sulphate of lime, men» 

 tioned page 331, with a cup of agate by abestus ; and, filling 

 them with purified water, made the platiiia wire in the cup 

 of sulphate of lime transmit the electricity from a power 

 of 100; a wire in the agate cup received it. In about 

 four hours a strong solution of lime was found in the agat* 

 cup, and sulphuric acid in the cup of sulphate of lime. Bj 

 reversing the order, and carrying on the process for m 

 similar time, i^Q sulphuric acid appeiired in the agate cup, 

 and the solution of lime on the opposite side. 



Many trials were made with other saline substances, witU
