volatile oleofum, Spirit of Lavender, dulcified Spirit 
of Nitre, Peony- water, Daffy's Elixir, Helvetius’s 
Styptic, and fome other Mixtures where the Spirit 
has been very conftderably diluted ; likewife diftilled 
vegetable Oils, fuch as that of Turpentine, Lemon, 
Orange-peels, and Juniper; and even thofe of them 
which are fpecifically heavier than Water, as Oil of 
SalTafras; alfo refinous Subftances, fuch as Balfam Ca - 
pivi , and Turpentine j all which fend forth, when 
warmed, an inflammable Vapour. But exprefled 
vegetable Oils, as thofe of Olives, Linfecd, and Al- 
monds, as well as Tallow, all whofe Vapours are un- 
inflammable, I have not been able yet to fire ; but 
thefe indeed will not fire on the Application of 
lighted Paper. Befides, if thefe laft would fire with 
lighted Paper, unlefs their Vapours were inflamma- 
ble, I can fcarce conceive they would fire by Elec- 
tricity ; becaufe, in firing Spirits, ffc. I always per- 
ceive, that the Electricity fnaps, before it comes in 
Contact with their Surfaces, and therefore onlv fires 
their inflammable Vapours. 
As an excited Non electric emits aim, oft all its Fire, 
if once touch'd by a Non- electric not excited, I was 
defirous of being fatisfy’d, whether or no the Fire 
emitted would not be greater or lefs in proportion 
to the Volume of the electrified Body. In order to 
this, I procured an iron Bar about f Feet long, and 
near 170 Pounds in Weight; this I electrified lying 
on Cakes of Wax and Relin, but obferved the Flafhes 
arifing therefrom not more violent than thofe from 
a common Poker. In making this Experiment, be- 
ing willing to try the repul five Force, it once hap- 
pen'd, that whilfl the Bar was at one End electrifying,
