pending one Part thereof in filfc Lines cannot be 
fuppofed to produce any Effect. 
This Gentleman further obferves, “ That the Phial of 
“ Water fitted to irsWire does not receive the lead De« 
* c gree of Electricity, if its Wire, fufpended by a filk - 
IC Line, is applied to the Globe in Motion, or if that 
cc Phial is placed upon a dry glafs Stand.” This Mon- 
iieur le Mounter takes to be directly contrary to Mon- 
fieur du Fays Rule $ efpecially as the Phial cannot 
be replete with Electricity, unlefs, while it is ex- 
citing, lome non-electric Body touches the Phial 
below the Water. 
That the Phial of Water receives no Degree of 
Electricity in this Cafe is not ftrictly true : It receives 
as much as any other Mafs of Matter of the fame 
Bulk would, under the fame Circumftances. For we 
find, that we cannot highly electrify the Water, un- 
lefs the Electricity from the Globe be directed through 
the Water and Phial to the Non-electric in Con- 
tact ; in which Paffage a great Quantity thereof is 
accumulated, by its not pervading the Giafs fo faft 
as it is furnifhed by the Wire ; and therefore we find, 
that when the Water will contain no more, the Sur- 
charge runs off by the Wire: So that this Experi- 
ment, no more than thofe which precede, contra- 
di&s Monfieur du Fa/s Opinion 5 the Thinnefs of 
the Glafs permitting it, not wholly, but partially, 
to flop the Electricity. This Matter is explained 
further under Experiment the firft. j 
I differ from this ingenious Author with Reluc- 
tance, inafmuch as I greatly honour him, not only 
for h is Difcoveries upon the Subject of Electricity, 
but alfo tor the Pleafure and Improvement I received
