                                Diagram copied from the Register Book of the Royal Society.
At the meeting of the Royal Society on 4 September 1661, Sir Paul Neile brought in a paper, endorsed by the King, of Thomas Hobbes's proposal of how to double the cube (stated as finding two proportionals between two straight lines given). This is the diagram accompanying Hobbes's proof.
William Brouncker was asked to examine the proof, which he found erroneous, as registered in the next entry.

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.

                                At the meeting of the Royal Society on 4 September 1661, ‘A proposition of Mr. Hobbes for finding two mean proportionals between two strait lines given, was delivered to the Society by Sir Paul Neile from the king, indorsed with this majesty’s own hand, and was ordered to be registered; as was afterwards the answer to the problem, by lord viscount Brouncker’ (Birch 1:42). The date on which this was entered in the Register Book is given as 1 October, probably to await Brouncker's refutation.
