Investigating atmospheric electricity in normal cloudy conditions, but not during a thunderstorm. GF: windlass for raising and lowering a kite. AB: wooden frame supported by mahogony legs with glass cones covered with brass funnels to prevent glass getting wet. H: drawing spark from conductor and experiencing shock similar in strength to that from a fully charged Leyden jar. Leyden jar was attached to conductor, but it was not fully charged. Engraving from 'Practical Electricity and Galvanism' by John Cuthbertson (London, 1807).
