Some 300 guests of the Royal Society were received by the president of the.society, Sir Charles Sherrington, by the chairman of the General Board of the Laboratory, Sir Arthur Schuster, F.R.S., and the director, Sir Joseph E. Petavel, K. B.E , D. Sc., F. R. S. , at the National Physical Laboratory, Teddington, on Tuesday last. Among the guests we recognized Col. R. E. B. Cronin-ton, CH., Mr. G. W. Watson, Mr. T. B. Browne, Mr. L. A. Legros, Professor Hele-Shaw, Mr. Frank Churchill and a few others connected with the motor movement. In fact, it always surprises us to see so few associated with either the motor industry or movement at National Physical Laboratory functions.
The guests were shown over the numerous departments of the laboratory, and many interesting experiments and machines for research work were shown and explained by the staff. Of particular interest to the motor industry were machines for 'testing the efficiency of spur gears and others for testing the efficiency of chain drives. These were not new but they attracted attention, whilst of great interest were the experiments now being conducted in the determination of fatigue stresses in materials by the strain method. Test pieces with and without keyways and running under a bending strain disclose the effects of such strains in a very clear manner. A large amount of research is being carried out on lubricated journals at high pressures and temperatures. There was an exhibit of heat-treating castings of the aluminium alloy " Y " and of light alloy piston rings. In the metrology department and the optics and heat sections of the physics department and in the electrotechnics department we found much of a scientific nature to interest us but calling for far more space than could be devoted to it in this journal.
