The Elements of Hydrostatics

the highest part of the central line original: "middelliniens", and the line in such a proportion to its rational line, as the highest part with the upright, to the upright.

We have had such a helpful cause, as was intended to be explained. So it is with the Dutch language, and if anyone does not understand it, pray to him, beloved reader, that he learns it, rather than act like a fool in judging the Dutch language foolishly. Should anyone suggest to you that many will mock this new preciousness of the Dutch language, of which we have spoken more broadly elsewhere, when they hear of it, do not be troubled by that, for such is the course of the world; but think to yourself that their empty words, evidence of their own rejected vanity, will be easily trodden down by your substantial works, evidence of your praiseworthy fullness, while you enjoy what they must lack.

SHORT SUMMARY.

Argument Subject matter.

Definitions.

WE shall first describe the definitions of the specific terms of this Art, together with the postulates. Thereafter, the propositions, of which the first nine will explain several important properties of bodies in water. The 10th, 11th, 12th, 13th, 14th, and 15th propositions will concern the power of the pressure of water against bottoms. The 16th and 17th propositions, concerning the necessary lengths of the sides of the bottom to have a desired pressure of water against them. The 18th, 19th, and 20th propositions, concerning the center of gravity of the water pressures collected in bottoms. The 20th original text error: the author repeats 20, likely referring to the 21st in modern sequence proposition, to find its size through the weight of the water. The 21st and final proposition, concerning the
Proportions.

ratios existing between the size, specific gravity, and weight of bodies. After the aforementioned will still follow the Beginning of the Waterwichtdaet Hydrostatics.
