the Tube was held near the Hair-Line. Then I re- 
peated the Expriuaent with another Bubble, holding 
the Tube near the little End of the Pipe, and the 
Attraction was now much greater, the Leaf-Brafs 
being attracted to the Hight of near two Inches. 
March the ij'th, I repeated this Experiment after 
a fomewhat different Manner : The Pipe was now 
fufpended by two Lines of white fewing Silk, of about 
five Feet and a half long j thefe were hung upon two 
Nails drove into the Beam of my Chamber, diftant from 
each other about a Foot, by Loops at the other End of 
the Lines, by which the Pipe was fufpended ; then the 
Bubble being blown, by holding the Tube to the little 
End of the Pipe, the Bubble attracted the Leaf-Brafs 
to the Hight of near four Inches. This Experiment 
was made to fee whether fluid Bodies would not have

April 8, 1730, I made the following Experiment 
on a Boy between eight and nine Years of Age. His 
Weight, with his Cloaths on, was forty-feven Pounds 
ten Ounces. I fufpended him in a horizontal Pofiticn, 
by two Hair-Lines, fuch as Cloaths are dried on : 
They were about thirteen Feet long, with Loops at 
each End. There was drove into the Beam of my 
Chamber, which was a Foot thick, a Pair of Hooks 
oppofite to each other, and two Feet from thefe another 
Pair in the fame manner. Upon thefe Hooks the Lines 
were hung by their Loops, fo as to be in the Manner 
of two Swings, the lower Parts hanging within about 
two Feet of the Floor of the Room : Then the Boy 
was laid on thefe Lines with his Face down wards, 
one of the Lines being put under his Breaft, the other 
x under
