Once again the Society looks back on a year of scientific work, the 24th since its foundation.^[1]She is especially grateful to the Reich government, which has shown full appreciation of the important problems to be solved and has rated its financial support accordingly.^[2]Notably the Kaiser Wilhelm Institute of Physics should be mentioned here, the construction of which can now be begun with the support of the Rockefeller Foundation,^[3]once the Reich government has most generously removed the obstacles that still stand in the way by guaranteeing the annual budget.^[4]The Institute will be erected on a site in Dahlem (Berlin), which had already been acquired for this purpose some years ago.^[5]Prof. Peter Debye, presently still at Leipzig,^[6]has been chosen to assume the directorship. With the beginning of this construction a wish that the Society had been fostering for years will be fulfilled.[⁷]
