The British Institute of Radiology Exhibition for 1930, which was held in the Central Hall, Westminster, on December 3, 4, and 5, again testified to the great care, thought, and energy lavished upon it by those responsible for its organization. It was held in the same Hall as the 1929 exhibition, and there were signs that before long an even larger hall will be necessary to display to advantage the many and varied exhibits.Musical selections were played at intervals on a large electric gramophone kindly provided by Messrs. Philips. This innovation imparted an air of cheerfulness and was very much appreciated.There were in all twenty-seven stands occupied by twenty-two exhibiting firms; we welcomed two exhibitors who were absent last year.
