fons {landing upon the Wax are made electrical 
enough to fire the Spirit, the Threads repel each 
other at their lower Parrs, where they are not con- 
fin'd, to a confiderable Difiance ; and this Dlftance is 
in Proportion as the Threads are made electrical. 
If two Perfons (land upon electrical Cakes at about 
a Yards Difiance from each other, one of which 
Perfons, for the fake of Difiinction, we will call A , 
the other B > if A, when electrified, touches B, A 
lofes almoft all his Electricity at that Touch only, 
which is received by B , and flopped by the electrical 
Cake : If A is immediately electrified again to the 
fame Degree as before, and touches B , the Snapping 
is lefs upon the Touch $ and this Snapping, upon 
electrifying A , grows lefs and lefs, till B, being im- 
pregnated with Electricity, though received at Inter- 
vals, the Snapping will no longer be fenfible. 
That Glafs will repel and not conduct the Elec- 
tricity of Glafs, has been mention’d by others, who 
have treated of this Subject ; but the Experiments 
to determine this Matter mufi be conducted with a 
great deal of Caution ,- for, unlefs the glafs Tube, 
intended to conduct the Electricity, be as warm as 
the external Air, it will feem to prove the contrary, 
unlefs in very dry Places and Seafons. Thus I fome- 
times have brought a cold though dry glafs Tube 
near three Feet long into a Room where there has 
been a Number of People 5 when, upon placing the 
Tube upon ftlk Lines, and laying fome Leaf- Silver 
upon a Card at one End, and rubbing another glafs 
Tube at the other, the Silver has, contrary to Ex- 
pectation, been thrown off as readily as. from an 
iron Rod. At firft I was furprifed at this Appear- 
ance 5
