                                Design of Denis Papin's improvement of an equicrural siphon, probably reported to the Royal Society on 27 May 1685 and ordered to be registered. In the years 1685 and 1686, Papin became interested in using the siphon mechanism to create a perpetual fountain, as published in Philosophical Transactions of the Royal Society, vol. 15, no. 178 (December 1685).

                                At the meeting on 20 May 1685, the secretary Francis Aston read a letter, ‘from Dr. Reiselius, dated at Stutgard, April 5, 1685, desiring that some books might be sent to the Duke of Wirtemberg [Württemberg], and mentioning, that the aequicrural syphon had worked at above thirty feet high. Mr. Aston was ordered to consult with Dr. Papin in giving an account of such experiments, as had been made concerning that syphon before the Society’ (Birch 4:401). Papin probably reported on the siphon with some improvements the following week, but it is not recorded in the minutes of the meeting.
