himfelf, that I might fee there was an Attraction $ 
which 1 faw, though I perceived it not to be fo ftrong, 
as when the Attraction was carried by a longer Line, 
by returning it, as in the Experiments above-menti- 
oned. The Length of the Line was 65-0 Feet. This 
was feveral Times repeated, but the Experiment being 
made in the Evening, at length the Dew began to fall. 
We began about Seven o’Clock, or fome little Time 
after, but before Eight the Attradion ceafed: But 
whether this was caufed by the Dew falling, or by 
my being very hot, we could not pofitively fay, but 
I' rather impute it to the latter. This Experiment was 
made July 14, 1719. 
Note, That though we call the carrying the Elec- 
trick Vertue by the Lines in this Petition Horizontal, 
you are not tounderftand it in a ftrict Senfe, as may 1 
be eafily perceived by the Defcription of the Method ; 
and That as the Line fwagged down much below the 
Silk Lines that fupported it, in the middle Part between 
thofe Lines, it was fome Feet longer than the Diftance 
of the Poles. 
Some Days after this Experiment was repeated from 
the Turret Clofet Window,, when the Line was 7 65 
Feet, and the Attraction was no lefs perceivable than 
in the Experiment above-mentioned.
