The exceeding smallness of some of these Bodies.  By what means the hollowness of these small pipes was discover’d:  several Phaenomena_ 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 Phaenomena 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 Phaenomena explicable hereby.  Several Quaeries 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 explication of filtration, and several other Phaenomena; such as the motion of Bodies on the surface of Liquors; several Experiments mention’d to this purpose.  Of the height to which the water may rise in these Pipes; and a conjecture about the juices of Vegetables, & the use of their pores.  A further explication of Congruity:  And an attempt of solving the Phaenomena of the strange Experiment of the suspension of the Mercury at a much greater height then thirty inches.  The efficacy of immediate contact, and the reason of it._

Observ. 7.  Of Glass drops.

Several Experiments made with these small Bodies.  The manner of the breaking and flawing of them, explicated by Figures.  What other bodies will be flawed much in the same manner:  so other tryals, and a description of the Drops themselves:  some conjectures at the cause of the Phaenomena_, indeavoured to be made probable by several Arguments and Experiments.  An Experiment of the expansion of Water by heat, and shrinking by cold:  the like Proprieties suppos’d in Glass drops, and what effects proceed from them:  the seven Propositions on which the conjectures are grounded.  Experiments to shew, that bodies expand by heat.  The manner of making Thermometers, and the Instrument for graduating them.  The manner of graduating them, and their use:  Other Experiments to prove the expansion of bodies by heat.  Four experimental Arguments to prove the expansion of Glass by heat:  further prov’d by the Experiment of boyling Alabaster; which is explicated.
