The path ismade up of sixteen divisions, sothat the ball, starting at the ele-vated end of the groove, passesacross the table, forward andback, until it reaches the lowerend, which is then elevated to en-able the ball to run back to thestarting point, which is again raised, and so on. Attached to one end of the table is a rod leading upward to an armplaced at right angles on the end of a shaft driven in the usual the ball reaches the depressed end of the table, it strikes a springwhich releases a catch holding the shaft, which is thereby permitted tomake a half turn, and its arm is correspondingly moved to raise or depressthat end of the table to which the connecting rod is attached. The ballthen runs down the table, strikes a similarly arranged spring at the op-posite end, when the movements are repeated and the position of thetable again reversed. It takes fifteen seconds for the ball to travel fromone to the other end of the 702. ELECTRICAL CORRECTION OF CLOCKS. For a clock that gains some second or two per seconds before each hour the lever,D B, is attracted by the electro-magnet. A,and a pin in the arm, D, would thereuponenter and catch a tooth of the escape wheel,did the disk, M, allow the other arm of thelever, E, to move. When the hand reachesthe hour, E falls, then D catches S andholds it till the cessation of the current atthe sixtieth second of the governing clock.
