R. S. In the Account of fome of the earlier eledri- 
cal Experiments made by Mr. Gray, Phil. Tranf 
N°. 366. we are informed, that he eledrified ie- 
veral other Bodies, befides animal Subflances, by 
drawing them between his Thumb and Fingers, 
in particular, Linnen ofdivers Sorts, Paper, and Fir- 
Shavings, which would not only be attracted to 
his Hand, but attrad all fmall Bodies to them, as 
other eledric Bodies do. Now, notwithstanding 
this laft Circumftance of their attrading, as well as 
being attraded, may it not be queftioned, Whe- 
ther, in this Way of Trial, it appears that they 
are eledrical Bodies, or Eledrics per fe? Is it not 
doubtful (fince his Fingers muft be excited con- 
fiderably in this Experiment) whether he did not 
communicate Eledricity to them from his Hand, 
rather than excite it in them ? I have no doubt but 
that the Principle is inherent in many other Bodies 
befides Animal, pofiibly, in all Bodies whatever 5 
But as it is allow’d, I fuppofe generally, that Ani- 
mals have a greater Quantity of it refiding in them, 
than other Subflances, there feems Room to admit 
the Doubt I have mention’d, which I fubmit to 
the Confideration of fueh as are curious in Expe« 
riments of this kind,
