Beautiful cr3-stalswere soon formed in the immersed part of the tube, and alayer of the liquid acid remained above.

The knife, which likewise is con-structed of hard bronze, carries two arms at right angles,one of which engages in the aperture in the crosspiece, andthe other in a groove that the piston rod carries. The appa-ratus works as follows: In the initial position, the valves, S and S, are closed,and the two others, s and s, are open. The inflow-ing water communicates with the bottom of the piston,while the top is in communication with the outflowingwater. The piston , and the knife arm engageswith the groove in the piston-rod. But, when thislatter reaches the limit of its travel, the bottom of thegroove rests on the arm, forces the knife to describe arotary motion, which has the effect of stretching thespring. During this time the other knife-arm slides inthe aperture of the crosspiece, and, at the precise mo-ment at which, through its presence there, it is aboutto ch
