fect arifes from their being brought near excited Non- 
eleCtrics. 
2^, That inflammable Subflances are fired by the 
repullive Power of Electricity; when it happens, that 
the inflammable Subflances, being firfl electrified 
themfelves, are fired by being brought near Non- 
eleCtrics not excited. 
This Matter will be better illuftrated by an Exam- 
ple. Suppofe that either a Man handing upon a 
Cake of Wax, or a Sword fufpended in filk Lines, 
are electrified, and the Spirit, being brought near 
them, is fired, this is faid to be performed by the 
attractive Power of Electricity. But if the Man elec- 
trified, as before, holds a Spoon in his Hand contain- 
ing the Spirit, or the fame Spoon and Spirit are 
placed upon the Sword, and a Perfon not electrified 
applies his Finger near the Spoon, and the Spirit is 
fired from the Flame arifing from the Spoon and 
Spirit upon fuch Application, this I call being fired 
by the repullive Power. Of the two mention’d Kinds 
I generally find the repullive Power ftrongeft. 
Since my laft Communication, the Spirit has been 
fired both by the attractive and repulfive Power thro* 
four Perfons Handing upon eleCtrical Cakes, each 
communicating with the other, either by the Means 
of a Walking- cane, a Sword, or any other non- 
electric Subftance. It has likewife been fired from 
the Handle of a Sword held in the Hand of a third 
Perfon.
