<p>An investigation dealing with the adaptation of the resistance thermometer to calorimetric and other uses for which the ordinary form is not suited. The first part of the paper contains a description of the instrument and its calibration, the second part deals with the determination of the transition-point of sodium sulphate by means of two of the thermometers. The value found by Richard and Wells was 32.888 degrees C.; the redetermination by the authors gave 32.384 degrees .
