T H E Approbation the former Communication of 
my Ele&rical Experiments ( Lranfaft. Numb. 
417.) to the Royal Society did meet with, by their moil: 
generous Encouragement, hath been a great Inducement 
to me to go on with them, to fee what farther Difcove- 
ries I can make upon the SubjeCt of this Species of At- 
traftion. I {hall at prefent communicate only two Ex- 
periments j the firft (hewing that Water may have an 
Attractive Vertue communicated to it from an EleCtrick 
Body ; the other, that Water is not only attracted by 
the T ube, or any other abfolutely Eleclrick Body, but 
that this Attraction is attended with feveral remarkable 
Circumftances. 
I. In the former Account of my Experiments, I, 
deferibed the manner of communicating an Attraction 
to a Bubble of foaped Watery but I have now found, 
that even a Body of Water receives an AttraB ive 
Fertile, and alfo a Repelling one y by applying the ex- 
cited Lube near it , after the fame manner as folid 
Bodies do. To perforin this Experiment, I caufed 
a wooden Diih to be turned, with a Screw*hole at the 
Bottom, but not fo far as to come through the Wood : 
This was ferewed on to the upper End of one of 
the Stands I have mentioned in the other Experiments,, 
the other Top being taken off : The Diih was about
