Early History of Lightning

CAN any of your readers refer me to the sources of some of the late Mr Richard Anderson's information with regard to the early history of the lightning-conductor? (1) On p 27 of the third edition (1885) of his book ``Lightning-Conductors '' he states that Franklin in the 1758 issue of ``Poor Richard '' gave directions for the erection of lightning-conductors

Atmosphere

In the lightning rods categorized as Early Streamer Emission (ESE) types an intermittent voltage impulse is applied to the lightning rod to modulate the electric field at its tip in an attempt to speed up the initiation of a connecting leader from the lightning rod when it is under the influence of a stepped leader moving down from the cloud In this paper it is shown that due to the
