Our experiment gives a totally different result from that obtained by Messrs. Daniell and Miller. According to their results, the solution in the upper cylinder should have lost 0.2965 gr. Cu during the electrolysis.

We will next consider whether the transference remains constant for all current strengths. To obtain an answer to this question, the above solution was subjected to the action of a weak and of a strong current.

The current from a Grove cell was so cut down by the introduction of a long thin German-silver wire, that at a temperature of 5.3° C. it reduced 1.2273 gr. Ag in 18 hours and 4 minutes, or 0.00113 gr. Ag per minute.

The quantity of silver corresponds to 0.3597 gr. Cu.

There was deposited on the silver cone 0.3587 gr. Cu.

The solution about the cathode contained:

The quantity of transferred copper is therefore

The current from three Grove cells reduced at 6.5° C. 1.1503 gr. Ag in 2 hours, or 0.00958 gr. Ag a minute.

This quantity of silver corresponds to 0.3372 gr. Cu.

There was deposited on the silver cone 0.3374 gr. Cu.
