Shape a common Vinegar- Crewet, is then prepared, 
full of Water and well corked, with an iron Wire 
running through the Cork almoft to the Bottom, and 
emerging fome two or three Inches above it, our of 
the Top of the Phial. The Head of this Wife is 
bent, to catch in the loweft Link of the Chain 5 and 
is to be there fufpended, when it has been electrified. 
From the Mouth of the Barrel, which is pointed in, 
a Line parallel to the equatorial Plane of the revolving 
Spheroid, comes a long iron Wire, inferted into the Bar- 
rel itfelf, as far as one Third of its Length, and thence 
proceeding till it touches the glafs Spheroids to a 
ContaCt with which it is determined by one of the 
filken Loops I mentioned above in the Defcription of 
the Apparatus. Every thing being thus difpofed, the 
Gun-Barrel is to be electrified by repeated Revolu- 
tions of the glafs Spheroid ; which is to be in a con- 
tinual Conta£t with the long Wire that proceeds 
from it. The Phial is, at the fame time, to be elec- 
trified by the Operator, who takes hold of the Body 
of the Bottle, and applies to the electrifying Spheroid 
the bent Extremity of that Wire, which palfes from 
near the Bottom of the Phial through the Cork, as I 
defcribed above. The Operator muft take care not 
to touch the Wire itfelf, while he endeavours to 
eleCtrify the Phial ; otherwife he would be in the 
Cafe of one, who fhould aim to eleCtrify himfelf, 
without ftanding upon fome one of the Bodies, 
that are EleCtrics per fe. When the Phial is fuf- 
eiently electrified, which will be done in eight or 
ten Revolutions of the Spheroid ; for I would not 
have any one be too free in bellowing fuch an Ef- 
ficacy upon it by too long an Application, as might 
perhaps*,
