iO the Body of it fome Woollen Threads fy’d to a fticfc, 
which was plac'd in it as an Axis, and being fix’d on the 
Machine, the great Wheel was turn'd, and the Hand ap- 
ply’d as ufual, but foon I found the Inconvenience of a 
cilafsof that form, the Threads entangling one with ano- 
ther, and there was no way to loofe or feparate them ; 
however they feem’d then to me to be difpos’d (had they 
been at Liberty) to have anfvver’d my expe&ation. But 
this is not all that occurr’d at that time, for bringing my 
Hand near the Glafs, which was then at reft, I was fur- 
prrzd to fee a Motion of the Bodies within fide ; and 
upon enquiry, found it was occafion’d by the Approach 
of my Hand, fince I could by amotion of my Finger to- 
wards the Point of any of the Threads that touched not 
the infide of the Glafs (but nerely fo was beft) drive it 
any way ; it feem’d to fly my Finger held on any fide of 
it, and this without touching the outward furface by half 
an Inch or more. Now when this Experiment was made 
by hanging the Threads near the outfide, it was very odd 
fas before related) to fee them fly the Approach of a 
Finger; yet how much more furprizing is it, to fee the 
fame perform’d even when a Body fo folid as Glafs inter- 
pofes ; which (hews the fubtilty of the Effluvia, the Body 
from which it is produc’d feeming to be no Impediment to 
its motion Befides it feems very much to referable or 
emulate a Solid, fince Motion may be given to a Body, 
by pufhing the Effluvia at fome diftance from it : But 
what is ftill moreftrange is. That this Body f I prefume 
to call it fo) altho' fo fubtil as feemingly to per via te 
Glafs, will not (as I have taken notice of in a former Ex- 
periment) affeft a light Body thro’ a piece of Mnflin: 
Now whether the Muffin abforps the Effluvium, or what 
other Laws it may be fubjeft to, I cannot tell, but fure I 
am ’tis very amazing, and I think, with fubmiffion, wor- 
thy the Confideration of this Honourable Society.
