 MOUNTAIN SCHEHALLIEN for finding its ATTRACTION : PROPOSAL for MEASURING the ATTRACT- 

 ION of some HILL in the Kingdom by Astronomical Observations 2 vols. 4to. in 1 (pp. 45 and 

 7), sewn, with AUTHOR'S INSCR. (see below) ; RARE, 15s 1776 



As a result of his observations for determining the attraction of mountains by deviations of the plumb-line, the author 

 found 11". 6 as the sum of contrary deflexions east and west of the hill. From this JAMES HUTTON (<j. v. ante) deduced the 

 mean density of the earth as 4.5 (but actually, according to the latest researches, 5.53). For these investigations Maskelyne 

 was awarded the Copley medal. He also was the inventor of the prismatic micrometer.
