INVITATION TO RUSSIA SIR, —Apropos of the emigration of prominent German

scientists and technicians to Russia, a recent issue of the Gottinger Universitinszeitung enlightens us somewhat on that subject. Many experts have already " accepted " the ehrenvollen Ruf to continue their special research in Russia. One prominent physicist, however, declined to accept such an invitation when it came to him. He was then placed "under observation" for a few days, with the result that it was announced that Professor X, the eminent physicist, had finally decided to accept this call, feeling "greatly honoured" by his being "selected.".—Yours truly,
