The procedure is described for calculating the dimensions of the different components of a temperature control system consisting of conducting and insulating layers outside the thermostat, and absorbing, and in some cases insulating layers between the thermostat compartment and the quartz plate mounting.
A method is explained for observing and empirically reducing the effect of variations of room temperature on the controlled temperature of the apparatus. This effect depends on the relative positions of the thermostat, the heater, and the quartz plate. It is usually the limiting factor in precision of control.

A new method is described for measuring the contact potential differences between dissimilar metals. It enables one to measure the p.d. to 1/1000 volt in a few seconds of manipulation. An apparatus is described for studying metals in air and another is described for high vacuum work.
