    Description
    A figure showing a large cylindrical glass full of water with a piece of ice floating in it, and the position of the observer's eye. This accompanies a paper entitled 'Of the Refraction of Ice' by Robert Hooke. The paper was read at the meeting of the Royal Society on 11 February 1663.

    The original drawing by Hooke is at Cl.P/20/11. Other copies can be found at RBO/2i/150, RBO/2ii/113, RBC/1/337 and RB/1/20/256.

    Object history
    At the meeting of the Royal Society on 11 February 1663, ‘An experiment of the refraction of ice was made by Mr. Hooke and an account of it given by him in writing, which was read, and ordered to be registered. He was desired to try it the next day with a glass of the same figure with the piece used by him in the experiment of this day’ (Birch 1:193).

    Printed in Robert Hooke, Philosophical Experiments and Observations (London, 1726), pp. 24-26, with a much altered figure at p. 25.
