Includes a sketch of Denis Papin's new contrivance of a fountain shown to the Royal Society in June 1685. The image was printed in Philosophical Transactions of the Royal Society, vol. 15, no. 173 (1685) to advertise the invention as a 'riddle' for others to guess its design, which was a way to claim priority.

This appears to be Robert Moray's attempt to work out its design, but with a plea to have it suppressed if it did not work. Perhaps this is the reason why Moray's name is crossed out in ink in the accompanying text.
