                                The diagram is one of a series of figures (fols 363-70) in John Wallis's explanation of the raising of a weight by inflating a bladder. In this diagram, ACDF is supposed to be the beam of a balance, with C at the centre. This diagram continues from the previous one with a three-dimensional view of the movement. Wallis read his paper at the meeting of the Royal Society on 4 March 1663.
These figured are copied from the series in RBO/2i/168-75.
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 March 1663, ‘Dr. Wallis brought in his account of the experiment, wherein a weight is raised by the blowing of a bladder; demonstrating it by the principles of statics applied to the particular case; and it was ordered to be registered’ (Birch 1:206).
