Fourteen pound required 64 ounces ; and 2 1 pound 
required 9 4 ounces. 
I placed another axis in the fame ballance, the pevets 
of which were 1 inch diameter, and lufpended 7 pound 
on each arm at 18 inches diftance from the center, 
which required 3 A ounces to be applied to either 
end, to overcome therefiftance from fridtion 5 and then 
that end funk near 2 inches. 
Fourteen pound, applied in the fame manner, re- 
quired 74. ounces, which carried that end down fome- 
what more than 2 inches. 
Twenty one pound required 1 1 1 ounces, and funk 
either end 24 inches. 
Seven pound, fufpended on each arm at nine inches 
diftance from the center, required 74 ounces to move 
cither end. — Fourteen pound required jounces, and 
21 pound required 20 4 ounces. 
On repeating thefe experiments, there was little or 
no variation ; and altho the feverai powers, required to 
overcome the refinance from fridtion, do not cor- 
refpond exadtly in proportion to the feverai weights 
and diftances; yet it appears, that the lead: power 
required, was equal to 4 the weight on the pevets ; and 
that it required a power nearly equal to the whole 
weight, to overcome the refiftance from fridtion, with 
but a fmall degree of velocity. But it does not fol- 
low, that the extraordinary power, feemingly required 
to overcome the fridtion with this degree of velocity, 
is to be attributed entirely to that caufe, as part of it 
is neceffary to raife the oppofite weight with the fame 
degree of velocity, tho’ fome part of it certainly is. 
For when there is little or no obftrudtion from Iridt ion, 
a power
