This paper, tending to establish the chemical action of atmospherical electricity, is based upon experiments made in Malta between October 1834 and March 1835. The mode of operating was the following: A tube of glass containing a wire of copper was elevated six feet in all above a turret in Dr Davy's house in Valletta, which rose just fifty feet from the street. It was not in the highest part of the town, and was overtopped by other buildings. To the lower part of the copper-wire was attached one of gold. The communication to the ground was effected through the medium of another copperwire, connected with a leaden cistern.
