Clapton, Jane 21. 1S12. ThOMAS loRSTER. 



* While the obliquely descendinsf and an,2;ular fihres nf the rims ap- 

 peared to be equal'zing the electricity of the surrounding air, they were 

 albO carried gently forward by the wind: this shows that wind may pass, 

 through a mass of atraosphere wiiliout destroying the inequality of its elec- 

 tricity, which is slowly elTected by the agency of ics proper conductor, the 

 tirnis.
