In the great clocks before us, to obtain the performance of all the oscillations in equal times, the action of the force applied was required to be the same in manner, quantity, and duration in each oscillation; conditions of such difficulty under the constant changes of friction and resistance, that the happy introduction of the pendulum - converting a rotatory into a vibratory motion, and by its own gravity and isochronism neutralizing the impediments to uniform movement - was assuredly the grandest and most decisive stride ever made in horology. And that this benefit was widely and at once appreciated, is manifested by the fact, that at least eight-tenths of the portable clocks of those times, now existing, have obviously undergone the necessary alterations to fit them for the pendulum. The early efforts in horology consisted inbelonging to the Society of Antiquaries.
