The attradlion of the hill, computed in a rough man- 
ner, on fuppolition of its denhty being equal to the mean 
denlity of the earth, and the force of attracfion being in- 
verfely as the fquares of the dilfances, comes out about 
double this. Whence it flrould follow, that the denlity of 
the hill is about half the mean denlity of the earth. But 
this point cannot be properly fettled till the figure and di- 
menhons of the hill have been calculated from the fur- 
vey, and thence the attracflion of the hill, found from the 
calculation of leveral feparate parts of it, into which it is 
to be divided, which will be a work of much time and 
labour; the refult of which, wall be communicated at 
fome future opportunity. 
Having thus come to a happy end of this experiment, 
we may now conlider feveral confequences flowing from 
it, tending to illuftrate fome important queflions in na- 
tural philofophy. 
1. It appears from this experiment, that the moun- 
tain SchehalUen exerts a fenflble attraction; therefore, 
from the rules of philofophifing, we are to conclude, that 
every mountain, and indeed every particle of the earth, 
is endued with the fame jiroperty, in proportion to its 
quantity of matter. 
2. The law of the variation of this force, in the in- 
verfe ratio of the fquares of the diftances, as laid down by 
Sir ISAAC NEWTON, is alfo confirmed by this experiment. 
For, if the force of attraffion of the hill had been only to 
that of the earth, as the matter in the hill to that of the 
earth, and had not been greatly increafed by the near ap-^
