The HISTORY of

of the Weight of Distill'd-water, Snow-water, May-dew, Rain-water, Spring-water: of augmenting the weight of Liquor, by dissolving Salts: of the greater thickness of such Water at the Bottom than at the Top: of weighing ascending and descending Bodies in Water; of the pressure of the Water at several Depths under its Surface.

Experiments of the heat and cold of the Water, at several depths of the Sea: of propagating sounds through the Water: of sounding the Depth of the Sea without a Line: of fetching up Water from the Bottom of the Sea: of fetching up Earth, Sand, Plants, from the Bottom of the Sea.

Experiments of the Resistance of Water to Bodies mov'd on its Surface, of several Figures, and by several Degrees of Force: of the Resistance of Water to Bodies mov'd through its Substance, ascending and descending: of the Expansion and Condensation of Water by Heat and Cold: of the Condensation of Water by several Ways of Pressure: of converting Water into a vapourous Air, lasting some time in that Form: the Torricellian Experiment try'd with Water in a Glass-Cane thirty six and forty Foot high, in a leaden Tube, also with a Glass at the Top: the same try'd with Oil, and other Liquors.

Experiments of the rising of Water in small Tubes, and many others about its Congruity: of Filtration, or of the rising of Water to a great Height in Sand, &c. of the swimming of Fishes: of Waters being able to penetrate through those Pores, where Air will not: of opening Bellows at a Depth under Water, and blowing up Bladders, to find the Pressure of the Water: of Water not subsiding in a high Glass-Cane upon removing the ambient Pressure, after it had been well ex-
