Description
Diagram of a weight hung at the bottom of a bladder, whose neck is fastened to a post. The bladder can be inflated through a quill inserted at the top. As the bladder is inflated the weight is raised. This diagram was in William Croone's paper, which was presented to the Royal Society on 6 November 1661. This was further discussed by John Wallis on 4 March 1663.
This image is copied from RBO/1/108. Another copy can be found in RBC/1/112.
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.
