The word cylinder is used in a conventional sense only, since the cavities acting as such are circular, whose axes, instead of being straight lines, are arcs of circles struck from the center at which the axes of the shafts would, if continued, intersect. The four pistons are carried upon the gimbal ring, which connects, by means of pivots, the two chair couplings.
The eyes, small and squinting, were so deeply sunken, the eyebrows and cheek-bones so prominent, that under the yellowish forehead could be seen two sockets, literally filled with darkness, and, at a small distance, the eyes seemed to disappear in the bottom of these cavities, two black holes, which give such a horrible appearance to a skull.
The sides of the bags are sometimes closely approximated; but, when the bags are less flattened, their cavities are, usually, filled with numerous, irregularly rounded, hollow bodies, having the same kind of wall as the large ones, but not more than one seven-hundredth of an inch in diameter.
"The nerves of the machine which I am describing," he says, "may very well be compared to the pipes of these waterworks; its muscles and its tendons to the other various engines and springs which seem to move them; its animal spirits to the water which impels them, of which the heart is the fountain; while the cavities of the brain are the central office.

The spirit of intrigue lurked behind her low, cruel brow. Long hairs had grown from her wrinkled chin, betraying the masculine character of her schemes.
Inch by inch, he enlarged the rift, crept into it, and found himself on a fragment of the bow of one of the foundation arches, which, though partly destroyed, still supported itself, isolated from all connection with the part of the upper wall which it had once sustained, and which had gradually crumbled away into the cavities below.

In ascending the scale the furrow in the tongue increases as we come to the higher notes. It is here that the back of the palate begins to draw up in order to add to the resonance of the head notes, giving the cavities of the head free play.
