ire producea current opposite to that which had brought about the polarisa-tion. The secondary current thus obtained gradually becomesweaker, and soon disappears, unless the polarisation is kept up byan extraneous cause. This is done in what is known as Grovels gas hattery, a singlecell of which is… … Fig. 147. tubes contain dilute sulphuric acid, and the current of a batteryis passed until the tubes are filled with oxygen and hydrogenrespectively. Contact with the battery is then broken, and theelectrodes are connected either directlyor through a galvanometer ; the polarisa-tion current is then…
