It was fortunate for science that Mr Davy survived this severe malady without any injury to his constitution, or any diminution of his mental powers. He resumed his enquiries with his wonted ardour, and by the liberality of the managers and principal members of the Royal Institution, he was furnished with the means of pursuing them with success. During his convalescence, a voltaic battery of 600 double plates, each four inches square, was constructed and placed at his disposal; and not long afterwards, when a more powerful apparatus was thought desirable, the munificence of a few individuals supplied him with another battery of no less than 2000 plates.This powerful artillery was now directed against the earths; but the task of these analyses was more difficult than he expected.
