Many patents have been taken out in this branch of electrochemistry, but it is to be remarked that that granted to C. Watt traversed the whole of the ground.
There he continued his literary and scientific labours, enjoying congenial intercourse with such men as Matthew Boulton, James Keir, James Watt and Erasmus Darwin at the periodical dinners of the Lunar Society.
It was here that, on his invitation, James Watt constructed a model of his steam-engine, which was tested in a now disused colliery.
About the same time he made the acquaintance of two men of scientific attainments - Gregory Watt (1777-1804), a son of James Watt, and Davies Giddy, afterwards Gilbert (1767-1839), who was president of the Royal Society from 1827 to 1831.
The execution of Watt gave to this trial a note of tragedy which was absent from that of certain members of the Corresponding Society, accused of conspiring to murder the king by means of a poisoned arrow shot from an air-gun.
