Pofture, if he touches the Wood- work of the Ma- 
chine with one Hand, and applies a Finger of his 
other near the Guft- barrel, at that Inftant he receives 
the electrical Strokes. Thefe continue as long as 
he touches the Machine, but ceafe upon his remo- 
ving his Hand therefrom. Here we fee a Circula- 
tion of Part of this Man’s electrical Fire, which ope- 
rates in the following manner. Firftj The Man, by 
applying one of his Hands to the Machine, becomes 
a Part thereof 5 and, by the Motion of the Globes, 
Part of the electrical Fire, inherent in his Body, is 
driven upon the Gun-barrel s but it is inftantaneoufly 
reftored to him again, upon his touching the Gun- 
barrel with his other Hand. Thus he continues com- 
municating the Fire with one Hand, and having it 
reftored to him with the other, as long as he pleafes. 
If, inftead of touching the Machine or Gun- barrel, 
he holds his Finger near either or both of them, 
you fee the Fire go out, and return back, as in a 
former Experiment. 
62. It may be perhaps imagin’d, if one Man touches 
the Machine, himfeif and the Machine both being 
placed upon the Wax, and if another, (landing upon the 
Floor, conftantly, or by turns, touches the Gun-barrel, 
that by thefe means the Man upon the Originally- elec- 
trics might be diverted of all his electrical Fire, by con- 
ftantly continuing the Motion of the Globes, as he 
receives then no Supply from the Floor. But the 
contrary proves true 5 and, after a confiderable time, 
the Strokes from the Gun-barrel are as ftrong as at 
firft. But here we muft obferve, that the Gun- 
barrel fufpended will not contain probably at one 
time a thoufandth Part of the whole Quantity of
