4* Bat this Flux of electrical JEther, either 
from the Floor to the Man, or from the Man 
to the Water, is prevented for Reafons fufficiently 
obvious, if the Glafs containing the Water be thick } 
if the Points of non-eledric Contact are few j if the 
Man is placed upon Originaily-ele&rics, or (which is 
the fame thing) if the Soles of his Shoes are dry. 
5. As we find that the Electricity paffes at leaft 
equally quick through denfe Mediums, which are 
Non-eledrics, as through thofe which are more lax 
and fpongy j may we nor therefore conclude, that 
the Caufe why we feel molt Pain at the Joints of 
our Arms, and in the Tendons of our Heels -f*, 
arifes from the Texture in the Tendons and tendi- 
nous Ligaments of thofe Parts ? 
6$\ From a due Confideration of the 'Phenomena 
before us, I take the Liberty of propofing the fol- 
lowing Queries : 
1. Whether or no the Effeds we obferve, in 
Bodies being drawn to and driven from either ex- 
cited Originally-eledrics, or excited Non-eledrics, 
are to be attributed to the Flux of eledrical ^Ether > 
2. 
f This Pain in the Heels is felt only in the Experiment with the 
eleCtrical Mine ; and it is not perceptible only when you touch the 
lower fmall Wire with your Foot, but likewife if you (land upon 
Non-ele£trics, which touch this Wire. It has been ftrongly felt 
by a Perfon {landing upon a Pedeflal of Portland Stone near ten 
Inches in Height, and upon one of Metal more than two Feet. I 
am of Opinion, that no Mafs of Metal, of Dimenfions however 
great, would in the lead prevent the Progrefs of the electrical 
Power from the Water in the Phials to the Body of the Man.
