attracted by them s and if I ftaid longer, I could not 
perceive any repul five Force remaining. 
I ought to tell you, that when I had, by feveral 
Trials, found out about what time the Effluvia 
would be quite diffipated, I forbore making any 
Trials till then, left that, by bringing the Tube or 
Cane near the Body of Trial, I might communicate frefh 
Effluvia y and perpetuate the State of Repulfion 
longer than it would otherwife have been 5 fo that, 
in the laft Trials I made, I never came near with the 
Tube, &c y till full twenty Minutes after the Body 
of Trial was put into a State of Repulfion. I ob- 
ferved not any material Difference of Time between 
the Diftipation oi the Effluvia of the glafs Tube, and 
thofe of the Wax Cane, when the fame Body of 
Trial was made ufe of for both: If there was any 
Difference, I think the vitreous Effluvia were the 
moft lading. 
I made another Trial with the Cane and Tube in 
a dark Room 5 being led to it from a Sufpicion I had, 
that the Effluvia from the wax Cane were groffer, 
and more in Quantity, than thofe from the glafs 
Tubes and, upon exciting both as quick as I could 
in Succeffion, I found the luminous Effluvia , when 
I brought my Forefinger near the Wax, to proceed in 
a much greater Quantity to the Cane from the Tip of 
Finger, than they did on the fame Trial with the 
Tube of Glafs. And I feveral times obferved a fmali 
globular Spot of Fire to appear firft on my Finger, 
from which ifiued regular Streams in Form of a 
Comets Tail*
