Content object


A diagram illustrating apparatus designed to fetch samples of water from any depth of the sea using a wooden bucket with a lid that remains open while the bucket descends, but closes when it begins to be drawn back up to the surface. The upper part of the diagram shows the first state of the apparatus as it is in operation and the lower part shows the second state.

The design was discussed at the meeting of the Royal Society on 30 September 1663, and was also entered into the Society's Register Book. The paper and the figure were 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 a copy from the original Register Books (RBO/2i/302; RBO/2ii/203r). Compare the original drawing for this apparatus by Hooke in Cl.P/20/23/001. Another copy can be found in RBC/2/093, and another version at Cl.P/20/35/003.

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.
