W and Ware rigid brass wires passing easily through slots in c, andsupported by means of nuts d and d\ the upper ends of Wand W being threaded ; b and b are small vulcanite blocksto which the rigid wires W and V\r/ are firmly attached. Apart of the surface / of block b is made conducting and inmetallic connexion with W ; likewise a conducting part ofsurface f is in metallic connexion with W. For holdingthe slab S, a clamp operated by the screw s is used ; formaking the necessary adjustments in the positions of S, thenuts e, d, df serve. The reason for making the surfaces /and/ partly conducting and in metallic connexion with Wand W7 respectively will be made clear when the methodused in making the field determination is described.
