Including ' New Experiments and Observations [made at the Pantheon] on the Nature and Use of Conductors,' by B. 

 Wilson (pp. 69). 



' He had a long coatroversy with Benjamin Franklin on the question whether lightning-conductors should be round or 

 pointed at the top [asserting that pointed conductors attracted the lightning 1, and was supported in his views by George 

 III., who declared his experiments were sufficient to convince the apple-women in Covent Garden.' — D. N. B. The above 

 was the author's last effort in the advocacy of ball-shaped conductors, which in the above case gained strength from the 

 fact that the Purfleet Powder Magazine, which was provided with pointed conductors, was struck by the lightning.

and 5 copperplates, 8vo. old calf [rare), 15s 1752 



The author was the first to use a conductor with the collector of his cylinder electrical machine. He also found that 

 the electric property of tourmaline was shared by other crystals. He received the Royal Society's gold medal in 1760 for 

 his electrical experiments.
