"If the strong tube, or barrel, be smooth, and equal on the inside, and there be fitted to it the solid piston, or plug a, so as to work up and down, air tight, by the handle b, the air in the barrel may be compressed into a space a hundred times less than its usual bulk. Indeed, if the vessel be of sufficient strength, and the force employed sufficiently great, its bulk may be lessened a thousand times, or in any proportion, according to the force employed; and if kept in this state for years, it will regain its former bulk the instant the pressure is removed." —Comstock, 1850

A hydraulic press is a hydraulic mechanism for applying a large lifting or compressive force. It is the hydraulic equivalent of a mechanical lever, and is also known as a Bramah press after the inventor, Joseph Bramah, of England. He invented and was issued a patent on this press in 1795. Hydraulic presses are the most commonly-used and efficient form of modern press.

"Since the strength of the fibers in adhesion is very much less than in tension and compression, adhesion enters into nearly every test as an important factor. Thus, if a piece of wood consisting of several fibers is tested in tension, the fibers a and b would probably not break at all, but be merely pulled out, the failure, as far as they are concerned, being due to lack of adhesion and not to a lack of tensile strength. Every tension test presents numerous cases of this king, the broken fibers presenting no even fracture, but being splintered and drawn out especially if the wood is good."—Government Printing Office, 1897
