    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).
