XIX. Some Things concerning Electricity^ by 
the Rev. J. T. Defaguliers, LL. 2). F. R. S. 
B O U T a Year or Two ago, in a Paper I gave 
in to the Royal Society*, I endeavoured to 
eftabiifh Tome general Principles concerning Electri- 
city, from the Confideration of many Experiments, 
which have been tried by others, as well as fome 
new Experiments by myfelf, an Account of which I 
then gave. Therefore I fhall only now repeat my 
DiftinCtion of all Bodies into Two Clafies, in refpeCt 
of Eledricity, and make good the Definitions that I 
gave b.y fome further Experiments; and though I do 
not pretend to know the Caufe of Electricity in 
general, yet I hope from a few Laws of Electricity, 
deduced from known c Phtenomem, to folve moft 
other Thanomena* (tho* feeming quite unaccount- 
able) fo far as to fhew what Law of Electricity they 
depend upon ; and to be able to foretel what will 
happen to moft Bodies, before the Experiments are 
tried upon them in an Electrical Way. 
i. Bodies EleCtric per fe are fuch in whom a 
Virtue of attracting and repelling fmall Bodies at a 
Diftance is inherent, though it is not always in 
ACtion, fo as to produce that EffeCt. But by rubbing, 
patting with the Hand, hammering, warming, and 
fometimes only expofmg to dry Air, fuch Bodies 
exert the Virtue above-mentioned; other wife they 
arc in a Non-elcCtric State. 
a. Non-cleCtric Bodies are fuch in which no Elec- 
trical Virtue can be excited by any ACtion upon the
