The steel wire db has adiameter of 0*8 mm., and is as smoothand round as possible; the twistingof the silver wire can easily bemanaged by first stretching it loosely and then turning thesteel wire in the direction of the arrow. The silver wirebeing now well stretched, db is held in position by the torsionwhich it produces in the thinner steel wires ac and bd; these 1 See XIII. p.
