Frame, at about half its Height, the Pivot that receives 
one of the Poles of the glafs Spheroid is fixed j the 
other Pivot, on the oppofite Side, is a round long 
Bar of Iron, fcrewed into and paffing through the 
Poft, in order to fix, or give Liberty of removing the 
eledrifying Glafs. This Bar of Iron, for the Conve- 
niency of turning it, has another in the Nature of a 
Leaver, which paffes through its Extremity at right 
Angles with it. The whole Machine is mounted 
upon a Floor of Boards, Wheel, Frame, Glafs, &c. 
and employs two Men, the one to turn the Wheel, 
the other to fit behind the glafs Spheroid, and apply 
the Concave of each Hand to its lower convex Sur- 
face; for it is by this Fridion that the Electricity is 
excited. 
When the eledrifying Glafs has been fome little 
time in Motion, the Perfon who defires to be elec- 
trified, applies the Extremities of the Nails of one 
Hand, and ftands not upon Cakes ofW ax, as in England, 
but within the Area of a fquare Drawer or Box about 
five Inches deep, and filled with five Parts Pitch, four 
of Refin, and one of Bees-wax : I will not call it a 
Compofition, for they are not mixed, but difpofed 
in the following Manner ; the Pitch is placed next 
to the Sides of the Box, and rifes almoft to a Level 
with them, the Refin in the Middle is level with the 
Pitch, and the Wax forms a thin Surface, covering 
both to a Level with the Box it fielf ; however, I fup- 
pofe this to be in it felf very indifferent, and that 
any one Body of the Eledrics per fe would anfwcr 
equally.
