                                At the meeting of the Royal Society on 12 November 1674, ‘Dr. Wallis presented them with, and read before them, a discourse of gravity and gravitation grounded on experimental observations, and having a reference to two books not long before published by an anonymous author, the one intitled an Essay concerning Gravitation or Non-Gravitation of Fluids; the other, Difficiles Nugae: or some Observations touching the Toricellian Experiments, etc. [both by Sir Matthew Hale]. The doctor was thanked for this discourse, which was ordered to be entered into the Register-book’ (Birch 3:143).
