Ball of Cork ftuck on the little End of it, under which 
the Leaf-Brafs being laid, and the Tube rubbed and 
held near his Feet, the Ball at trailed the Leaf-Brafs 
to the Hight of two Inches, and repelled it, and at- 
tracted for feveral Times together with great Vi- 
gour. 
April xi, I again repeated the Experiment on the 
Boy j and now he attracted much ftrongerthan at the 
firfl: The Leaf-Brafs rofe to his Face at the Hight of 
more than twelve Inches. Then I gave the Boy to 
hold in each Hand the Tops of two Fiihing-Rods, 
with a Ball of Cork on each of their leffer Ends , then 
a fmall Stand being fet under each Ball, with the 
Leaf-Brafs on it, the Tube being rubbed, and held 
near his Feet, both the Corks attraded and repelled 
together ftrongly. The Length of the Poles were 
each of them about feven Feet. Then the Boy was 
laid, on his left Side, and a Filhing-Rod, of near twelve 
Feet in Length, given him to hold with both his 
Hands j there was a fmall Ball of Cork at the End of 
the Rod, that was an Inch and three quarters Diame- 
ter : Then all Things being prepared, the Tube held 
near the Boy’s Feet, the Cork Ball attracted and repelled 
the Leaf-Brafs with Force to the Hight of at leaft two 
Inches. 
Note, That when Ifpeakof holding the Tube near 
the Boy’s Feet, I mean over againft the Soles of his 
Feet s and when near his Head, is to be under- 
ftood the Crown of his Head ; for when the Tube is 
held above, or over his Legs, the Attraction is not fo 
ftrongly communicated to the other Parts of his 
Body.
