iron Bars, and at its other End was placed another 
Spoon : This fecond Spoon touched the Handle of the 
third, which was placed under one End of the other 
fquare Bar, whole other End came near to the Spirit in 
the fourth Spoon, the Handle of which lay upon a 
Weight; and under this was placed a W ire conne&ed to 
thefhort iron Rod, with which the Explofion was made, 
when the coated Phial was charged. When the Phial 
was well charged, if the Spirit of Wine fent forth 
Vapours, and the, fquare iron Bars were at a proper 
Diftance from it; upon making the Explofion at the 
Gun-barrel the Electricity fnapped between the Spi- 
rit and the iron Bars, and the Spirit was fet on Eire 
at the fame Inftant in all the Spoons. It fometimes 
happened, that fome of them only were fired. If 
the iron Bars were too near the Spirit, it was not 
fired, though the Circuit was completed ; becaufe 
then no ele&rical Flame fnapped between the Rods 
and Spirit ; that Effect happening only, when the 
Parts of the Non-electrics deferibing the Circuit 
are not in immediate Contact; on the other hand, 
if the Space left between the Bars and Spirit was 
too great, the Circuit could not be completed, and 
there would be no Explofion. 
§ XXI. This Experiment will feem more fur- 
priling in the following manner. When the Appa- 
ratus is difpofed of as before, the tail Wire from 
the coated Phial, before it reaches to the Table, is 
fatten'd to an iron Rod {landing in a Pail of Water: 
Another iron Rod is like wife placed in the fame 
Pail of Water, and a Wire from this laft reaches 
under the W eight, which fupports the firft of the 
before^
