Exp. x.] The pendulous Cylinder is {hot by the 
Springfromo Deg. to 7 Deg. meafured upon a Tan. 
gent Line. 
Exp. 2.] The Cylinder with a leaden Weight in 
it that makes its Weight double, is (hot forward to 
4 Deg. and 9 Tenths. 
Exp. 3.] The Cylinder with a Weight in it that 
made its Weight triple, was {hot forward to 4 Degrees 
and a little farther. 
Exp. 4.3 The Cylinder with a triple Weight of 
Lead fo as to quadruple the whole Weight, was {hot 
forward to 3 Deg. and an half.. 
Thefe 4 Experiments at firft feem agreeable to the 
newHypothefis ; for according to the old, the Cylin- 
der in the 2d Experiment ought to have gone but to 
3 t Deg. in the 3d Experiment but to 3- 7 Deg.. and in 
the laft but to 2 Deg; 
But if we take in the Confideration of Time, all will 
be reduc’d to the old Principle. As for Example, let 
us compare the firft and laft Experiments. 
In the firft, the Spring during a certain time a&s 
upon the Cylinder which is driven forward with the 
Velocity 0 . When the quadrupled Weight is driven 
forward with, the Velocity 4 inftead of 2, it is be=~ 
caufe the fame Spring ads twice as long upon the Cy- 
linder before it ceafes to impel it-, and certainly the 
feme Caufeafting twice as long muft produce a double. 
Effed.
