Thus by truing the section of the periphery of the grinding wheel to a radius propor- tionate to that of the roller, the movement of the wheel with respect to the job will reproduce that of the roller around the template, and the cutter will be accurately ground to the desired profile. ?HE TAYLOR-HOBSON RESEARCH LABOR4TORY, LEICESTER. CORRESPONDENCE DEVICE FOR CONTROLLING THE HA4UGHTON-HAKSON THERMOSTAT THE device described by Mr J. D. Grogan in his paper in the July issue of this Jou~lznl is of great value in connexion with the annealing of metallic specimens in order to attain equilibrium condition. In many cases this can be done much more readily by cooling the specimen very slowly through a transformation than by heating at a temperature a few degrees below the transformation. Dr Hanson and the writer tried many methods for doing this (most of which are described in their papers referred to by bIr Grogan), and finally obtained the most satisfactory results by immersing the bulb B of Fig.
