...there was any considerable difference of expansion between brass, steel, iron, copper, silver, &c., when exposed to the same degree of heat, as nearly...expected from it, since it was easy to shorten the column in any degree required. The only doubt I entertained was lest there should not be a proportional expansion... | |

...supposed this alteration has proceeded from a change of length in the pendulum itself, by the influence of heat and cold upon it, in the different seasons...expected from it, since it was easy to shorten the column in any degree required." As his first jar was too long, so his second was too short, but by June 9,... | |
