1086 HANDBOOK OF PROJECTION FOR Plante reasoned the action out as follows and no one has yet discovered any fault in his reasoning. His view was that when he connected the two lead plates to the generator, it was the electric current flowing from the D. Negative Group E. Positive Group Figure 403. generator which had caused the lead peroxide to form on the positive plate and made the other plate pure, spongy lead. That when he disconnected the generator and then connected these two plates to an electric circuit, the current which flowed was the result of a chemical action in the battery. That is, the sulphuric acid combined chemically with both the positive and negative plate to form lead sulphate on each. The electric power was given off as this chemical reaction went on and when the chemical action stopped, due to all the lead peroxide of the positive and pure lead of the negative plate being converted to lead sulphate, the electric power also stopped. We can therefore understand that the current which flows from a charged battery through an electric circuit, is produced by the chemical action which goes on in a battery; that is to say, the chemical formation of lead
