electricity of the black, or vice verfa ; in that cafe, 
the phial will not be electrified at all. 
The charging of the phial was among the fird of 
my experiments with eledtrified dockings. By fome 
trials I made in the month of December lad, I found 
it would fucceed. One frody evening in that month, 
having thrown into a fmail phial, filled with quick- 
filver, the electricity of one black docking, I receiv- 
ed from the explodon a fmart blow upon my finger. 
With the eledtricity of two dockings, the blow reach- 
ed both my elbows 3 and, by the means of four, I 
kindled fpirits of wine in a tea-fpoon, which I held 
in my hand, and, at the fame time, I felt the blow 
from my elbows to my bread. It may not, however, 
be improper to obferve, that the electricity, in this 
cafe, was excited by means of the leg. 
From what hath been faid in the preceding pages, 
it is evident, that all the remarkable appearances of 
electricity, hitherto difcovered, may be exhibited by 
a fimple apparatus of black and white lilk. But this 
is not all : in the courfe of experiments above-men- 
tioned, fomething curious has occurred to my obfer- 
vation, of which I do not find that any notice has 
been taken by others. — What I mean, is, a drong 
cohefion produced by eleCtricity. But as this paper 
is already extended to a great length, I diall referve 
the account of eleCtrical cohefion for another, which 
I fhall foon have the honour of prefenting to the 
Society.
