per,1 through which the inlet tube A and the U-shaped outlet tube B pass. The inlet tube A should be inserted at a slight angle so that its lower end lies in the center of the round-bottomed tube within half an inch of the bottom. This end is covered with a piece of fine bolting-silk fastened with a rubber band. The bolting-silk breaks the force of the inflowing water, but more especially prevents the entrance of any foreign substance which might close the outlet. The upper end of tube A is connected by a rubber tube to the distilled water reservoir or faucet. The flow of water is regulated by screw compressor C. The outlet tube B has its inner arm a trifle longer than the outer arm, so that the U does The stopper and small tubes must fit tightly to maintain an air chamber between the stopper and the lower end of tube B. not act as a syphon. The inner arm of this tube is covered with bolting-silk also, to prevent the escape of any material which may float.2
