flopped. So that the Cakes commonly made ufe of 
to flop the Electricity, by being too thin, fuffer 
confiderable Quantity of the ele&rical Power to per- 
vade them, and be loft in the Floor. I make no 
Doubt, if the electrical Power could be more in- 
creafed, it would penetrate much further through 
thefe Originally- eleCtric Bodies. 
Propojition III. 
Electricity, in common with Light likewife, when 
its Forces are collected, and a proper Direction given 
thereto upon a proper ObjeCt, produces Fire and 
Flame. 
Corollary. 
The Fire of Electricity (as I have before obferv'd) 
is, extremely delicate, and fets on Fire, as far as I 
have yet experienced, only inflammable Vapours. 
Nor is this Flame at all heighten'd by being fuper- 
induced upon an iron -Rod, red-hot with coarfer 
culinary Fire, as in a preceding Experiment 5 nor 
diminifh’d by being directed upon cold Water. 
However, I was defirous of knowing if this Flame 
would be affeCted by a ftiil greater Degree of Cold ; 
and in order to determine this, I made an artificial 
Cold, by which the Mercuiy, in a very nice Ther- 
mometer ad j Lifted to Fahrenheit’s Scale, was de- 
prefied in about 4 Minutes from 15 Degrees above 
the freezing Point to 30 Degrees below it; that is, 
the Mercury fell 45 Degrees. From this cold Mix- 
ture, when eleCtrifled, the Flafhes were as powerful, 
and the Stroke as fmart, as from the red-hot Iron. 
I could have made the Cold more intenfe, but the 
above was fufficient for my Purpofe. This Experi- 
ment
