The resistance of the circuit in this determination was about0#03 ohm, and the condenser was charged by means of thewell-known von Helmholtz pendulum*, manufactured byL. Zimmermann, of Heidelberg. The usual manner ofmaking the connexions was, however, slightly modified, asindicated in fig. 4. Fig. 4. Battery ^ Earth Condenser Earth. The sections of the two steel bars attached to the lower partof the pendulum proper are denoted by A and B. Thebattery was always in connexion with A and insulated from B. * Helmholtz, Monatsberichte der Berliner Akad. May 25, 1871, p. 294. Lord Rayleigh on hderference Bands, 407 The binding-posts denoted by P and the metal parts attachedto them were insulated from each other by being fastened tohard rubber bases. As arranged, the circuit was completedby A coming in contact with the lever C, and broken by Bcoming in contact with the lever D. In order to insuregood contacts the surfaces at the points where the circuit wasmade and broken were plated with gold. By means of themicrometer-screw attached to one of the hard rubber bases,the time between the contacts that made and broke thecircuit could be varied. One complete turn of the drum,which was subdivided into one hundred divisions, corre-sponded to a difference in time of contacts, and conseque
