times, fetY'd me as the former 5 nor-could it be Reviv*<f 
again wkhont a new ow. In -this Experiment it was 
fomethiies obfervable, that the Glafi, when taken oat af- 
ter a vidcnt Attritioo, would be fo hot as not to be held 
in the naked hand Vv^'ithont a fenfible Offence. That the 
Woollen on which it rubb'd would not only appear diP 
colour'dH but fometimes perfe'dHy burnt through. Some- 
times upon making this Experimentj it has happened that a 
Light would be carried quite round the Glafs Globe^ 
thereby making a continued Circle of it, during its Mo* 
tion, notwithftanding it toucht the Woollen in no more 
parts than in the former Experiments, At other times, a 
perfeft H^lo would difcover itfelf around the Stagnant 
Light 3 which feems to me to proceed from fome few 
drops of Water, that wil! fometsmes Infinuate by the 
Spindle through the Box on the upper Br-afs Plate, where 
is always kept W^ter, to prevent the entrance of Air 
there. This Water defcending the Spindle till- it reacht 
fome more exteefive parr, would there, by the violence 
of the Motion given, be thrown all about the Receiver in 
fmall drops, fome of which were likely to fail on th^ 
Woollen, where being heated by the Morion of the pre* 
mentioned Glafs, evaporated, appearing as a Halo around 
the Light r for fince I made a Contrivance, to prevent 
the Waters fcattering, no fuch Appearance has hap- 
pened. 
Sometimes I have obferved the Light to break from the 
Agitated Glafs, in as odd a form as Lightning : Particular- 
ly at a time when I us'd fome Lift of Cloath, that had 
been drencht in Spirit of Wine, which was fatten d to 
one Arm of the Brafs Spring, on the other of which was 
ty'd (ome of the fame Lift, that had been fteept in Water 
impregnated with Salt-petre 5 but both the pieces of Lift 
were very well dry 'd before I made ufe of them,
