"A centrifugal pump differing from an ordinary centrifugal pumps in one feature only. The water rises through a suction pipe S, which divides so as to enter the pump wheel at the center on each side. The pump disk or wheel is very similar to a turbine wheel. it is keyed on a shaft driven by a belt on a fast and loose pulley arrangement at P. The water rotating in the pump disk presses outwards, and if the speed is sufficient a continuous flow is maintained through the pump and into the discharge pipe D. The special feature in this pump is that the water, discharged by the pump disk with a whirling velocity of not inconsiderable magnitude, is allowed to continue rotation in a chamber somewhat larger than the pump. The use of this whirlpool chamber was first suggested by Professor James Thomson." — Encyclopedia Britannica, 1893

"The reign of Louis the Fourteenth has been termed the Augustan age of France. This monarch had none of the commanding qualities which create a nation or an era, and he would not have been distinguished from common princes in common circumstances. Destitute himself of the true sentiment of greatness, he yet became, fortuitously, the instrument of great deeds, and his reign will always be a memorable period in history." — Goodrich, 1844
