Observata et dicta apud D. Hugenium, 06 June 1693
Notes of a conversation in Holland with Christian Huygens, concerning an 'horologium' to show hours, months, years, and planetary positions. More general mention of the work of numerous other scientists: Notably, Huygens disputes the notion of John Bernoulli (James Bernoulli's younger brother) that the curve of an inflated sail is part-catenary and part-circle, and warns that Newton ought not to be 'deflected' into theology or chemistry.

David Gregory's solution to Sir Edmund Halley's problem, proposed during Gregory's composition of the "Tract on Fluxions", of finding the rotary motion in a sphere struck by another sphere.
