ordinary Effeft is this. That a Drop of cold Water 
(for the Seeds contribute nothing, but add Confid- 
ence to the Water) fhould be the Medium of Fire 
and Flame ? 
Camphor is a vegetable Refin, and, ofconfequcnce, 
an Ele&ric per fe. This Subftance, notwithftanding 
its great Inflammability, will not take Fire from the 
Finger of a Man, or any other Body cledlrified, tho* 
made very warm, and the Vapours arife therefrom in 
great Abundance j becaufe, neither Electrics per j e 
excited, or electrified Bodies, exert their Force by 
fnapping upon Electrics per fe> though not excited. 
If you break Camphor final!, and warm it in a Spoon, 
it is not melted by Heat like other Refins j but, if 
that Heat were continued, it would ail prove vola- 
tile. To Camphor thus warm’d, the Finger of an 
electrified Man, a Sword, or fuch-like, will, in 
fnapping, exert its Force upon the Spoon, and the 
circumambient Vapour of the Camphor will be fired 
thereby, and light up the whole Quantity expofed. 
The fame Experiment fucceeds by therepulfive Power 
of Electricity. 
A Poker, thoroughly ignited, put into Spirit of 
Wine, or into the diftilled Oil of Vegetables, pro- 
duces no Flame in either. It indeed occafions the 
Vapours to arife from the Oil in great Abundance ; 
but if you electrify this heated Poker, the electrical 
Flafhcs prefently kindle Flame in either. The Expe- 
riment is the fame with Camphor. Thefe Experi- 
ments, as well as the following, fufficiently evince, 
that the electrical Fire is truly Flame, and that ex- 
tremely fubtil.
