Paper, 'A contrivance to avoid irregularities in a clock's motion occasioned by the action of heat and cold upon the pendulum' by George Graham
Reference number: CLP/3ii/20
Date: 18 April 1726
Description
Graham, a watchmaker, shares observations on the curiosities in the measuring of time. He notes that the vibrations of a pendulum are slower in summer than in winter, and suggests that this arises from a change of length in the pendulum itself, by the influences of heat and cold upon it, in the different seasons of the year.
