- n. In geometry: A solid which may be conceived as generated by the revolution of a rectangle about one of its sides: specifically called a right cylinder. The side of the generating rectangle forms the axis of the cylinder, and the adjacent sides generate circles which form the bases of the cylinder.
- n. In mech.: That chamber of a steam-engine in which the force of steam is exerted on the piston. See steam-engine.
- n. The barrel of an air-pump.
- n. A hollow metallic roller forming part of certain printing-machines. In cylinder-presses the cylinder is used only for giving the impression. See

- n. Any hollow body of cylindrical form.
- n. The chamber of a steam engine in which the piston is moved by the force of steam.

“It consists of a small wooden cylinder, about three quarters of an inch in diameter, and 3 in. long; at one end of the cylinder is a cavity which holds the combustible, which is confined only by pasteboard or membrane, so that, when ignited, it will blow straight into the heart of the principal charge; the two wires of the electric circuit, entering at the other end of the cylinder, terminate upon the little wooden disc which forms the bottom of this cavity, so that the end of one wire is about a quarter of an inch from the other; the electric circuit is completed by drawing a dash with a blacklead-pencil across the tiny space of the wooden surface connecting the two ends of wire; and the fusee is then charged.”
“Our 20th century based mindset will seem to be so quaint in 90 years, just as the thought of recording sound onto a wax cylinder is so primitive to us.”
