over the Surface of the Water, it made again twenty- 
more Revolutions from Weft to Eaft, only at a fmaller 
Diftance from the Ball, (for the Water muft make it 
heavier) but full as regular as before, and rather 
quicker: The Virtue of the Cake muft now have 
lafted about three quarters of an Hour. After refting 
about fix Minutes, I tried again with the String frdh 
wetted, the Bail and Cake continuing as before ; and 
had,. to my great Surprize, one hundred Revolutions 
in the Space of about twelve Minutes, the Revolu- 
tions being ftill quicker, and more regular, and nearer 
the Ball j and at the fixth Revolution of this laft 
Hundred, the Thread was attradted to the Surface of 
the Ball, and, being wet, did not difengage itfelf, till 
pulled away j yet after this, deferibed the remaining 
Ninety-four Revolutions of the Hundred, and feemed 
inclined to deferibe a great many more, but that I 
was forced to reft my Arm again, which I did for 
about eight Minutes, then tried again, the Thread 
being frefh wetted, and had feventy Revolutions at 
nearly the fame Diftance from the Ball in lefs than 
nine Minutes, all very regular, and without any At- 
traction of the Thread to the Ball. 1 refted agairi 
ftxteen Minutes, wer the Thread again, and held it 
as Lifual ; it was repelled at about half an Inch Diftance 
from the Ball, but feemed to have no Tendency to a 
circular Motion j yet after continuing ftationary 
about a Minute, I perceived a Motion about its Axis, 
about which it took feveral Turns; but ftill had little 
or no progreflive Motion, till about a Minute longer, 
when it began to move forward, and continued doing, 
fo from W eft to Eaft, for about thirty-three Revolu- 
tions, very regular, but flower than in the two laft 
Cafes,, the String having been held about ten Mi- 
nutesaj.
