"It seems evident then," wrote Davy, " that water, chemically pure, is decomposed by electricity into gaseous matter alone, into oxygène and hydrogène." In the following year Davy discovered the metals of the alkaline earths,... | |

...and thus did he establish, by an unbroken chain of incontrovertible evidence, the important truth, that " water, chemically pure, is decomposed by electricity...gaseous matter alone — into oxygen and hydrogen." Out of the foregoing train of research, very naturally sprang the consideration of the decomposing... | |
