Monficur du Fay> That Bodies newt receive 
u Electricity by Communication , unlefs they are 
u Supported by Bodies eleCtnc in their own Nature , 
ts does not always take place \ and that it is liable 
cc to great Exceptions For, firft, .in the Leyden 
Ci Experiment, the Phial filled with Water is ftrongly 
“ eledrified by Communication, even when carried 
<c in the Hand, which is not a Body eiedric by 
u Nature/' 
To this I anfwer, that Monfieur du Fays Rule is 
confirmed by all the Experiments yet made public, 
and even by that of Leyden quoted by our Author, 
or what is ufually called that of .ProfeiTor Mufchen - 
braeck. For, in this Experiment, is not the non- 
eiedric Water contained in and fupported bytheglafs 
Phial, which is, eiedric in its own Nature l Its being 
carried in the Hand is no more than its being placed 
on any other non-efedric Body, and therefore is no 
Proof againft the general PofiCion. It is well known, 
that if the Phial is made non-eledric by wetting its 
Outftde, fo as not to leave fqme Inches perfediy 
dry, between its Mouth, and that Part which is wet- 
ted, the Water and Phial part with the Eledricity 
as faft as they receive it, unlefs it is flopped by an- 
other Eiedric per fe. But of this I treated at large, 
in a Paper I lately did myfdf the Honour to com- 
municate. 
Secondly, our Author mentions, c f That all Ro~

“ Water fitted to a Wire, and which has already 
<c received a great deal of Virtue by Communica-
