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 o
