Abstract Share this page

MANY years ago, the late Rev. JOHN MICHELL, of this Society, contrived a method of determining the density of the earth, by rendering sensible the attraction of small quantities of matter ; but, as he was engaged in other pursuits, he did not complete the apparatus till a short time before his death, and did not live to make any experiments with it. After his death, the apparatus came to the Rev. FRANCIS JOHN HYDE WOLLASTON, Jacksonian Professor at Cambridge, who, not having conveni-ences for making experiments with it, in the manner he could wish, was so good as to give it to me. The apparatus is very simple ; it consists of a wooden arm; 6 feet long, made so as ,to unite great strength with little weight. This arm is suspended in an horizontal position, by • a. slender wire 40 inches long, and to each extremity is hung a leaden ball, about 2 inches in diameter; and the whole is in-closed in a narrow wooden case, to defend it from the wind.
