Description
A drawing of Denis Papin’s clepsydra (a water clock) on a piece of paper (188 x 146 mm), glued on to the page of the Register Book. At the meeting of the Royal Society on 4 November 1685, Denis Papin reported that he had constructed a clepsydra ‘in the manner of Monsieur Comier’.
The theologian and physician Claude Comiers (d. 1693) had designed a clepsydra, which he submitted to the Royal Academy of Sciences on 16 March 1669. His letter and drawing of the clepsydra are found in the papers of Christiaan Huygens, who was presumably asked to comment on the device (Christiaan Huygens, Œuvres Complètes (The Hague, 1895), vol. 6, 381-82 (no. 1714)). The device was constructed by Hubin Emailler, who included a figure of it in his Machines Nouvellement executees en partie inventees par Hubin Emailler (Paris: J. Cusson, 1673). Comiers’s account was also produced in Journal des sçavans (11 May 1676), 97-103.
