Similarly you can find a common boundary in the case of the parts of a solid, namely either a line or a plane.
Space, likewise, is a continuous quantity; for the parts of a solid occupy a certain space, and these have a common boundary; it follows that the parts of space also, which are occupied by the parts of the solid, have the same common boundary as the parts of the solid.
Yes, and I have delayed you by my hurry; the ludicrous state of solid
geometry, which, in natural order, should have followed, made me pass over this branch and go on to astronomy, or motion of solids
Almost immediately I recognised them for what they were, the dark openings of caves entering the solid

Another finds that the phenomena of precession and nutation require that the earth, if not entirely solid

In the first class, the works of the wise ancients; and the Histories, Biographies, and Essays of writers of more modern times--otherwise the Solid

In the center was a square, solid
monument of hewn stone.
To save you the trouble of wading through a lot of scientific detail, which I know you don't care about, I'll tell you that the story is about a queer idol of solid
gold, weighing many pounds, and, in consequence, of great value."
