    AIR-PUMP—ALABASTER A 53 Bunsen's water-air-pump. Air-pump, Sprengel's. This apparatus de- pends on the principle of converting the space to be exhausted into a torricellian vacuum. In the subjoined figure, c, d is a glass tube longer than a barometer, open at both ends, and connected by means of india-rubber tubing with a fuimel, A, filled with mercury and sup- ported by a stand. Mercury is allowed to fall in this tube at a rate regulated by a clamp at c; the lower end of the tube, c, d, fits in the flask B, wliich has a spout at the side a little higher than the lower end of c, A; the upper part has a branch at x to which a re- ceiver B can be tightly fixed. When the clamp at C is opened, the first portions of mercury which run out close the tube and prevent air from entering below. As the mercury is al- lowed to run down the exhaustion begins, and the whole length of the tube from x to d is fitted with cylinders of air and mercury, leav- ing a downward motion. Air and mercury escape through the spout of the bulb B, which is above the basin n, where the mercury is col- lected. It is poured back from time to time into the funnel A, to be repassed through the tube until the exhaustion is complete.
