the fame Notion by another Experiment : He 
brought fome Down near to the Tube, and then 
made the Mercury run from one End to the others 
and the Down was attra&ed, as the Mercury in its 
Motion paffed by it. 
Thefe Experiments he has repeated, and varied 
feveral Ways; and they have led him to conclude, 
that the ¥ hofphoras of the Barometer, known this 
great while, is not fo properly a c Phofphorus % as the 
Effeft of the Mercury ele&rifying the Tube of the 
Barometer. 
Mr. I Allamand has put Mercury into exhaufleci 
Tubes, and, when thefe are rubb'd, they give muck 
more Light than before,* there then come out from 
them on all Sides Rays of very lively Light. I have 
alfo feen at Leyden , at Mr. Mufchenhroedzs the Me- 
chanift s, an exhaufted Globe of Glafs, which, when 
rubb’d with the Hand, feem'd all fill'd with a very 
bright Fire. 
Several Perfons have obferved, that when they 
had been ele&rified, their Fulfes beat a little fafter 
than before. I have even myfelf felt, after having 
been ele&rified a pretty while together, a Senfation 
all over my Body : But within thefe few Weeks, 
fome Perfons have felt very fnarp Pains upon their 
being electrified. 
There is an Experiment that Mr. I' Allamand has 
tried 5 he eledrify'd a tin Tube, by means of a glafs 
Globe 5 he then took in his left Hand a Glafs full of 
Water, in which was dipped the End of a Wire 5 the 
other End of this Wire touched the eledrified tin Tube : 
He then touch'd, with a Finger of his right Hand, the 
eledrified Tube, and drew a Spark from it, when at the 
fame Inftant he felt a moft violent Shock all over his 
Hz Body,
