ciallv the being much in London $ where I faw laft 
Week fame cicatrical Experiments 5 in which new 
field of Refearches there ate daily new Difcoveries 
made : The adtivc ele&ric Fluid feems to be a great 
Agent, in Conjun&ion with the Air, in the Pro- 
duction of Fite. 
A warm thick Piece of Iron being fufpended by 
two filk Lines, had a warm very thick Piece of Brafs 
laid on it, on which was placed a common Hen’s Egg; 
When ele&rified, the Flafhes from the Iron were of 
a bright filvcr light Colour ; from the Brafs (efpe-

argue, that fome Particles of thofe different Bodies 
were carried off in the Flafhes, whence thefe dif- 
ferent Colours were exhibited. 
It is fufpe&ed that great Degrees of ele&rifying 
have occafion’d fome Women to mifearry ; and no 
Wonder that fuch fudden Shocks fhould do it. I 
wrote to Mr. King the Experimenter to electrify a 
Frog, while the Circulation of its Blood was viewed 
with a Microfcope, to fee if it accelerated its Mo- 
tion, which he has not yet done. 
He obferves, that a Piece of Linen that has never 
been wafhed, will foon give a good Degree of Elec- 
tricity to a large warm glafs Tube ; viz. on account 
of the mealy Pafte, which Weavers drefs the Linen 
with 5 and therefore any Piece of Linen thus dreffed 
will do. 
I gave an Account in the General Evening Eoft of 
S t ember laft of the great Benefit of Ventilators in 
wgate, and in the Succefs Frigate for Georgia, which 
lay five Months wind-bound in our Chanel with the 
Tranfports for Cape Breton , thejreft of which were
