 Weight of a Pendulum for Motion; of the Motion of pendulous Bodies of various Figures; to determine the Length of Pendulums, to find the Velocity of the Vibrations of a sounding String; to find the Velocity of Motion, propagated by a very long extended Wire; for explaining the Inflection of a strait Motion into a circular, by a supervening attractive Power towards the Center, in order to the explaining of the Motion of the Planets.

Experiments of the circular and complicated Motion of Pendulums, to explain the Hypothesis of the Moon's moving about the Earth; of comparing the Motions of a circular Pendulum, with the Motion of a strait one; of the Propagation of Motion from one Body to another; of the Reflection of Motion; of the vibrating Motion of Quicksilver in a crooked Pipe, imitating the Motion of a Pendulum; of communicating of the Strength of Powder for the bending of Springs; and thereby for making artificial Muscles, to command what Strength we desire.

The eleventh are Experiments Chymical, Mechanical, Optical; as of reducing the Flesh of Animals into a Liquor like Blood, by dissolving it in a certain Menstruum; of a great Facility of raising Water in Pipes of a large Bore; of brewing Beer with Bread, Barley, Oats, Wheat, and without melting; of precipitating Tartar out Wine by several Expedients; of a chemical Extraction of a volatile Spirit, and Salt out of Spunges; of examining Aurum fulminans after Explosion; of the Dissolution of Manna in Water, and of a chrystallising it again out of it, by Evaporation.
