"The plate A is 46 inches in diameter, and is composed of gun metal. These were put on by original graduation, mainly on the plan of Edward Troughton. One very great improvement in this engine is that the axis B is tubular, as seen at C. The object of this hollow is to receive the axis of the circle to be divided, so that it can be fixed flat to the plate by the clamps E, without having first to be detached from the axis and other parts to which it has already been carefully fitted. This obviates the necessity for resetting, which can hardly be done without some error. D is the tangent screw, and F the flame carrying it, which turns on carefully polished steel pivots. The screw is pressed against the edge of the plate by a spiral spring acting under the lever G, and by screwing the lever down the screw can be altogether removed from contact with the plate." — Encyclopedia Britannica, 1893

"Nature, pervades the air, where grow the modest blue-eyed violets, the fragrant trailing arbutus, spicy and sweet, the funny Jack-in-the-pulpit, without which no collection of wild flowers would be complete, and there also maybe found the rare and beautiful bloodroot, whose stay is so short one can scarce catch a glimpse of its pure, white blossoms ere they vanish." -Beard, 1906

"The click barrel-ratchet R is set upon another larger ratchet-wheel, with its teeth pointing the opposite way, and its click rT is set in the clock-frame. That ratchet is connected with the great wheel by a spring ss' pressing against the two pins s in the ratchet and s' in the wheel. When you wind up the weight, the click Tr prevents the ratchet from turning back or to the right; and as the spring ss' is kept by the weight in a state of tension equivalent to the weight itself it will drive the wheel to the left for a short distance, when its end s is held fast, with the same force as if that end was pulled forward by the weight; and as the great wheel has to move very little during the short time the clock is winding, the spring will keep the clock going long enough." — Encyclopedia Britanica, 1893

"On the top of a short pillar is placed a card, and on the card a brass bal. Beside the pillar is fixed a steel spring, with an apparatus for drawing it back. If the spring is drawn back and the suddenly released, it will drive the card from the top of the pillar, while the ball in consequence of its inertia will retain its place." —Quackenbos 1859

"A mountain and spring, showing how the principle of the syphon operates to produce the effect described. Suppose there is a crevice, or hollow in the rock from a to b, and a narrow fissure leading from it, in the form of the syphon, b c. The water from the rill fe, filling the hollow, up to the line a d, it will then discharge itself through the syphon, and continue to run until the water is exhausted down to the l g of the syphon b, when it will cease. Then the water from the rills continuing to run until the hollow is again filled up to the same line, the syphon again begins to act, and again discharges the contents of the reservoir as before, and thus the spring p, at one moment flows with great violence and the next moment ceases entirely." —Comstock, 1850
