The arrangement of the levers in the Forsyth SCALES. 471 scales* (Figs. 322 to 326), is such that the action of the weights placedupon them is direct, and the motion of the levers in weighing is down-ward, the same as if hung upon a steelyard beam. The pivots have steelbearing edges, and these rest upon flat steel plates. The levers are suspend-ed to the frame-work of the scales in steel-faced loops, which have steel.

Theplatforms of the scales are held in position by check-rods, which preventthem from moving out of place, without interfering with the downwardmotion necessary in weighing. By these means the least amount of frictionis caused, there being no lateral or twisting motion of the weighing ma-
