and lince confirm’d, by Mr. Le Monnier, who per- 
form’d them himfelf. 
1. He was convinced, that the high fituation, in 
which the bar of iron was commonly placed, is not 
abfolutely necelfary to produce the effects of electricity:: 
for a tin fpeaking trumpet fufpended upon filken cords 
about five or fix feet from the ground, has produced 
very particular figns of electricity. 
2. A man, placed upon a cake of refin, and hold- 
ing with his hand a; wooden pole, of about 18 feet 
long, round which an iron wire was twilled, was fo 
well eleftrifed, while it thunder’d, that fparks, which 
were very lively, were drawn from his face and hands. 
3. Having taken away the communication of the 
eledrical magazine with the iron wire, which hung 
from the great wooden pole (this magazine con- 
fided, as I have faid in my lad letter, of 6 great bars 
of iron, placed horizontally upon glafs bottles, about 
4 feet from the ground) I fay, this magazine was> 
drongly eleCtrifed, when the dormy cloud paffed in 
the zenith. 
4. A man, danding upon the eleCtrical cake in 
the middle of the garden, and limply holding »p one 
of his hands in the air, attracted with the other 
hand wood-lhavings, which were held to him upon 
a piece of lead. Whence it evidently follows, that 
the matter, which is the caufe of all the furpriling, 
phenomena, which electricity affords us, fills the at-, 
mofphere in the time of a dorm ; that it penetrates 
us 5 that we breathe it with the air; and that the 
height ufually given to the iron bar only ferves to in- 
tercept the far greater quantity of the eleClrical 
matter.
