blue Cone of Flame, with its Point towards the 
Wire. When the Hand is placed at a proper Di- 
ftance, the Blaft, like that of cold Air, is therefrom 
very manifeft. If you do not determine the Elec- 
tricity by thcfe means to a Point, the Diffipation of 
it is general, and from all Parts of the excited Non- 
electric > but if you do, by bringing your Hand near 
the Wire as before-mentioned, you fee the Manner 
of its being difcharged into the Floor, and fo into 
the Earth. Thefc Facts being fo, if my Concep- 
tions are true, that the glafs Globes circulate the 
electrical Fire, which they receive from their Fric- 
tion againft the Cushions, or the Hand of a Man, 
and which is conftantly fupplied to thefe laft from 
the Floors the Ingrefs of the electrical Fire, if the 
Machine, &c. are placed upon Electrics per fe> 
ought to be vifible, as well, as the Egrefs under the 
fame Circumftances s and this is demonftrated by 
Experiment, For if, while any unexcited Non- 
electrics touch the Gun-barrel, the Globes being in 
Motion, you bring your Finger, or a Piece of Wire 
near any Part of the Wood-Work of the Machine, 
but more efpecially the iron Axis of the Wheel $ 
you obferve the Brufh of blue Flame fet in from it 
to the Wood-Work. We always obferve, in this 
Experiment, that the lambent Flame from the End 
of the Wire pafies diverging into the Machine, and 
this continues fo long as the Gun-barrel is touch'd. 
So that here the Office of the Globes exaftly tallies 
with that of the Heart in Animals 5 which, as long 
as the Quantity of Blood is fupplied, propels it into 
the Arteries, and thefe all over the Syftem 5 or that 
of the Pump in Hydrofiatics. In the fame manner,
