Description

Diagram illustrating Robert Hooke's invention for sounding the sea without a long line, using instead a ball sunk to the bottom of the sea by a weight which is released as soon as it touches the sea-floor and returns to the surface.

It was discussed at the meeting of the Royal Society on 30 September 1663, and printed in Philosophical Transactions of the Royal Society, vol. 1, no. 9 (February 1666), and again in vol. 2, no. 24 (April 1667).

This is copied from RBO/2i/301 or RBO/2ii/203v. The original drawing of this apparatus by Hooke is at Cl.P/20/23/001. Other version can be found at Cl.P/20/35/002 and RBC/2/094.

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.
