Description

Figures showing an experimental apparatus designed by Robert Hooke to test water pressure after heavier or lighter objects have been submerged. Hooke's experiment was read to the meeting of the Royal Society on 14 January 1663.

Hooke's original drawings are at Cl.P/20/9/001-02. Other copies of these images can be found at RBO/2i/100, RBO/2ii/089-90 and RBC/1/311 and 313.

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.

Object history

At the meeting of the Royal Society on 14 January 1663, ‘Mr. Hooke’s two papers were read, the one containing an account of some trials for finding how much the pressure of the water is increased by the descent of heavier, or the ascent of lighter bodies therein; the other, containing an experiment concerning the different weight of cold and warm water: both which papers were ordered to be registered’ (Birch 1:174). The text is reproduced in Birch 1:174-76.
