Matter between the Obfervcrs, whether it be 
Water, Earth, or both. 
VI. That the electrical Commotion is equally ftrong, 
whether it is conducted by Water or dry Ground. 
VII. That if the Wire$, between the electrifying 
Machine and the Obfervers, are conducted upon 
dry Sticks, or other Subftances non-electric in a 
flight Degree only, the Effects of the electrical 
Power are much greater than when the Wires in 
their Progrefs touch the Ground, moift Vegeta- 
bles, or other Subftances in a great Degree non- 
electric. 
VIII. That by comparing the refpective Velocities 
of Electricity and Sound ; that of Electricity, in 
any of the Diftances yet experienced, is nearly 
inftantaneous. 
1 fhall conclude this Paper with obferving, that it 
was thought convenient to lay a Detail of all the 
Operations relating to thefe Experiments before the 
Society ; in confequence of which the Gentlemen 
may make thcmfelves Judges, how far the Deduc- 
tions here recited are warrantable from the Experi- 
ments. 
* The Gentlemen concerned were defirous, if 
poffible, of afeertaining the abfolute Velocity of 
Electricity 
* Thefe Expiriments to meafure the abfolute Velocity of Elec- 
tricity were made whilft this Paper was at the Prefs, but as they 
had fo near a Relation to the Experiments made the preceding Year, 
it was thought proper to infer* them here,
