    Author: Ellicott, John :: Year Vol (No) Month (or Chapter/Auction item): 1736 39 abridged :: Pages: 82-83
    Comments and/or Abstract > instrument to measure thermal expansion by Ellicott

(8303) A letter concerning the inventor of the pendulum to prevent irregularities of motion due to temperat
    Author: Short, James :: Year Vol (No) Month (or Chapter/Auction item): 1751 XLVII :: Pages: 283-287

    Author: Graham, George :: Year Vol (No) Month (or Chapter/Auction item): 34 vol 7 abstracts :: Pages: 129-132
    Comments and/or Abstract > Graham experiments with mercury pendulums

(8305) Some obersavations made in London, by Mr. George Graham; and at Black River Jamaica, by Mr. Colin Ca
    Author: Bradley :: Year Vol (No) Month (or Chapter/Auction item): 38 vol 7 abridged version :: Pages: 649
    Comments and/or Abstract > record of experiments using a clock built by Graham to measure the error between London and Jamaica. Clock was insensitive to driving weight and constructed so that pendulum could be removed and replaced with little error

    Author: Bailey, F :: Year Vol (No) Month (or Chapter/Auction item): 1832 122 :: Pages: 399-492
    Comments and/or Abstract > excellent but dated experimental paper - foundation for Stokes experiments. Includes information on how to deal with internal hollow spaces within pendulum

(10229) A new Absolute Determination of the Acceleration due to Gravity at the National Physical Laboratory, England
    Author: Cook A. H. :: 1967 vol 261 pages 211 - 252 Year Vol (No) Month (or Chapter/Auction item): :: Pages: 211 - 252
    Comments and/or Abstract > A new absolute determination of the acceleration due to gravity has been made by timing the free motion of a body moving under the attraction of gravity. The moving body is a glass sphere that was timed at its passage across two horizontal planes they the flashes of light it produced when it passed two horizontal slits.
