 Description of it:what other Bodies have the sharpest points: of the ruggedness of polisht Metal.A description of a printed point.Of very small writing, and the use of it for secret intelligence: the cause of the coursness of printed lines and points.

A description of it: the causes of its roughness: of the roughness of very well polisht Optick Glasses.

A description of it: A silken Flax mention'd, an attempt to explicate the Phænomena of it, with a conjecture at the cause of the gloss of Silk.

''A short description of it. A conjecture'' about the reason why Silk is so susceptible of vivid colours:and why ''Flax and Hair is not. A conjecture,'' that it may perhaps be possible to spin a kind of artificial Silk, out of some glutinous substance that may equalize natural Silk.

The great unaccurateness of artificial works. A description of a piece of water'd Silk; an Explication of the cause of the Phænomena: the way by which that operation is perform'd: some other Phænomena mention'd depending on the same cause.

The exceeding smallness of some of ''these Bodies. By what means the hollowness'' of these small pipes was discover'd: several Phænomena of it mention'd. An attempt to explicate them from the congruity and incongruity of ''Bodies: what those proprieties are. A'' hypothetical explication of fluidity: of the fluidity of the air, and several other Phænomena of it: of congruity & incongruity; illustrated with several Experiments: what effects may be ascrib'd to these properties: an explication of the roundness of the surface of fluid Bodies: how the ingress of fluid bodies into a small hole of an heterogenious body is hindred by incongruity; a multitude of Phænomena explicable hereby.Several Quæries propounded; 1. Concerning the propagation of light ''through differing mediums.2. Concerning'' ''Gravity.3. Concerning the'' roundness of the Sun, Moon, and Planets. 4. Concerning the roundness of Fruits, Stones, and divers artificial ''Bodies. His Highness Prince Rupert's way of making Shot. Of the roundness'' ''of Hail. Of the grain of'' Kettering ''Stone, and of the Sparks of fire.5. Concerning'' springiness and tenacity. 6. Concerning the original of Fountains; several Histories and Experiments ''relating thereto.7. Concerning'' the dissolution of Bodies in Liquors. 8. Concerning the universality of this Principle: what method was taken in ''making and applying experiments. The'' Rh
