fallingbody is as the space passed through, or thevelocity is as the square root of the space ;therefore the velocity acquired by the pendu-lum L in its descent from L to V is as \Zr V.But R V : V O: : V O : D V, consequently R V= V O -f- D V, and D V being a constantquantity, R V is as V O2, or… … the same. There are certain reasons whythe cycloidal pendulum is not available, whichI do not propose to discuss at this time; butI mentioned the fact that the centre of oscil-lation and the centre of gravity were notidentical, and perhaps it would be well tomore particularly notice this property…
