    Description
    Diagrams from William Brouncker’s paper (Cl.P/1/15/001) proving that the curve of isochronous descent is a cycloid (proved earlier by Huygens by other means), and that the centre of curvature of every point of the cycloid (evolute) is a cycloid. The paper was read at the meeting of the Royal Society on 22 January 1662 and sent on to Christian Huygens.

    This is copied from RBO/1/157. Another copy can be found at RBC/1/161.

    This volume is another copy of entries of the first two volumes of the Register Book. It was given to Sir Joseph Banks by G. S. Heales Esquire of Doctor's Common on 31 May 1814.
    Object history
    At the meeting of the Royal Society on 22 January 1662, ‘The pendulum experiment was discoursed of by the lord viscount Brouncker, who brought in the account and schemes of it; and a committee was appointed for making trials of it, consisting of his lordship himself, Mr. Boyle, Sir William Petty, Dr. Wilkins, and Dr. Wren. His lordship’s paper was ordered to be registered, and a copy of it made against the Friday following, and brought to Sir Robert Moray, to be sent to Mons. Huygens’ (Birch 1:70). The entire paper is printed in Birch 1:70-74.
