The same result followed when the brass cylinder attached to the lower end of the wire was twisted through about half a revolution and held in this twisted position for several hours. The time drift is thus quite easily removed. There remains, however, the change in equilibrium position with the temperature of the wire, as shown in Fig. 1. The next problem is then to study the effect of heat treatment on this temperature coefficient, which in Fig. 1 is — mm per °C. Fig. 2 sho
