Professor Andrews, by an ingenious arrangement, is enabled to show that
water is decomposed by the common machine; and by using an electrical
kite, he was able, in fine weather, to produce decomposition, although
so slowly that only 1/700000th of a grain of water was decomposed per
hour. Faraday has proved that the decomposition of one single grain of
water produces more electricity than is contained in the most powerful
flash of lightning.
