Strona 6 - And therefore, that nature may be lasting, the changes of corporeal things are to be placed only in the various separations and new associations and motions of these permanent particles; compound bodies being apt to break not in the midst of solid particles, but where those particles are laid together and only touch in a few points.
Strona 6 - ... solid, massy, hard, impenetrable, moveable particles, of such sizes and figures, and with such other properties, and in such proportion to space, as most conduced to the end for which he formed them; and that these primitive particles being solids, are incomparably harder than any porous bodies compounded of them; even so hard, as never to wear or break in pieces; no ordinary power being able to divide what God himself made one in the first creation.

Strona 10 - By common law: as where a person seised in fee-simple or in fee-tail dies, and his next heirs are two or more females, his daughters, sisters, aunts, cousins, or their representatives: in this case they shall all inherit, as will be more fully shown when we treat of descents hereafter; and these co-heirs are then called coparceners; or, for brevity, parceners only.
Strona 11 - In every quadrilateral inscribed in a circle, the rectangle of the two diagonals is equivalent to the sum of the rectangles of the opposite sides.
Strona 9 - ... sheathed with copper, he might easily have pierced it. But not being well skilled in the management of the vessel, in attempting to move to another place, he lost the ship. After seeking her in vain, for some time, he rowed some distance, and rose to the surface of the water, but found daylight had advanced so far, that he durst not renew the attempt. He says...
Strona 16 - When a man by the exertion of his rational powers has produced an original work, he seems to have clearly a right to dispose of that identical work as he pleases, and any attempt to vary the disposition he has made of it appears to be an invasion of that right.
Strona 11 - The result of my inquiries, in which it would be ludicrous to boast of impartiality, is that the unities of time and place are not essential to a just drama; that, though they may sometimes conduce to pleasure, they are always to be sacrificed to the nobler beauties of variety and instruction; and that a play written with nice observation of critical rules is to be contemplated as an elaborate curiosity, as the product of superfluous and ostentatious art, by which is shown rather what is possible...
