Experiment VII. 
Having rubb’d the Tube T /f,{fecTAB.I. Eig.U.) and 
with it attrafted a Feather, the Feather at t was repell’d 
from the Tube, whenever it was brought near it but 
fuddenly dipping the End T of the Tube in Water, 
the Feather floating in the Air came to it again, and 
ftuck to the End of the Tube at T or near jP. 
H.B. In fair Weather this Experiment will not 
fucceed, unlefs the Tube be thruft pretty deep into 
Water (a Foot at leafl) 5 but in moift Weather an Inch 
or two will do. 
S. Though animal Subftances be generally 
thought to be KkBrkal per fcy yet it is only when 
th^y are very dry ; This is the Reafon why a living 
Man fufpended by a Hair Rope, or ftanding upon a 
Cake of Rcfin, to receive Eledricity from the Tube, 
muft be confider’d as ^Nm-eleBricaly by reafon of 
the Fluids of his Body. 
N.B. The above Obfervations, together with the 
^eries in my former Papers, will be further illu- 
fl rated by fome Experirflents which I do not now 
mention, becaufe 1 have only try'd them at homej 
but when 1 have tryU them before the ^LoyaI/ 
Society, I lhall give an Account of th^, in 
Order. . -
