under his Thighs : Then the Leaf-Brafs was laid on 
a Stand, which was a round Board of a Foot Dia- 
meter, with white Paper parted on it, fupported on a 
Pedeftal of a Foot in Flight, which I often made ufeof 
in other Experiments,- though not till now mentioned,: 
Upon the Tube’s being rubbed, and held near his Feet, 
without touching them, the Leaf-Brafs was attracted 
by the Boy’s Face with much Vigour, fo as to rife to 
the Hight of eight, and fometimesten Inches. I put 
a great many Pieces on the Board together, and almoft 
all of them came up together at the fame Time. Then 
' the Boy was laid with his Face upwards, and the hind 
Part of his Head, which had fhort Hair on, attracted, 
butnot at quite fo great a Hight as his Face did. Then 
the Leaf-Brafs was placed under his Feet, his Shoes and 
Stockings being on, and the Tube held near his Head., 
his Feet attracted, but not altogether at fo great a Hight 
as his Head: Then the Leaf-Brafs was again laid un- 
der his Head, and the Tube held over it, but there 
was then no Attraction, nor was there any when the 
Leaf-Brafs was laid under his Feet, and the Tube held 
over them. 
April the 16th, I repeated the Experiment with the 
Boy, but now the Attraction was not quite fo ftrong as 
at the firft, the Brafs not rifing higher than to about 
fix Inches. His Hands being ftretched nearly hori- 
zontal, I placed a fmall Stand with Leaf-Brafs under 
each Hand, and under his Face the great one, furnifli- 
ed as the others j when the excited Tube being held 
near his Feet, there was an Attradion by his Hands 
and Face at the fame Time. I then gave him the Top 
of a Fi(hing-Rod to hold in his Hand j there was a
