Hand, and join with 2, 3, and 4, all {landing upon 
the Floor. If, under thefe Circumftances, the firft 
Line is ele&rified, and 4 touches ©, all eight are 
ftruck through. If 4 touches C, ©, though electri- 
fied, feels nothing, and the remaining feven are 
ftruck; fo that here © is left out of the Circuit. 
If 4 touches B, only fix feel the Shock, and C and 
© feel nothing; and thus you may proceed to A , 
who muft always neccflarily feel, if either himfelf 
or any of his Line is touched. If, when both Lines 
are as before-mention’d, © touches 3, 4 is left out 
of the Circuit, and the remaining feven feel the 
Stroke. If C touches 2, the Circuit confifts of five, 
©, 3, and 4 being, though under the fame Cir- 
cumftances, left out: Always obferying, however 
thefe Circuits are diverfified, that A, who touches 
the Gun-barrel, and 1, who holds the Phial, are cer- 
tain to feel the Stroke. 
38. This Experiment may be reverfcd, the Lines 
being as before, in the following manner, wherein 
likewife this Circuit is always obfervable. Let A 
( fee Tab. III.) touch the Gun-barrel as before, and 
© hold the Wire of the ele&rified Phial in his Fin- 
ger. Let 4 grafp the Phial, and 1 touch B ; then 
A feels nothing, being left out of the Circuit, and 
the other feven are ftruck. If 4 touches C, then A 
and B feel nothing, the Circuit confiding of the re- 
maining fix. But it is to be obferved, as in the for- 
mer Experiment, that 4, who grafps the Phial, and 
©, who holds the Wire, muft of Neceffity be al- 
ways in the Circuit. I have been the more particu- 
lar in this Matter, as it demonftrates the Courfe of
