Description
A diagram has been crossed out and corrected in the margin of the page. The diagram is one of a series of figures (RBO/2i/168, 169, 172, 174 and 175) in John Wallis's explanation of the raising of a weight by inflating a bladder. ACDF is a lever, supported at C, the fulcrum. A more extensive three-dimensional diagram follows on the next page (RBO/2i/169). Wallis read his paper at the meeting of the Royal Society on 4 March 1663.
