Dear Herr Hippke!
According to the agreement with the Reich Leader SS the low-pressure air chamber for experiments in the neighborhood of Munich is still to be available for two further months.
Moreover, Stabsarzt Dr. Rascher is, in addition to his tests in the Luftwaffe, to be on duty for the present for the purposes of the Reich Leader SS.
Heil Hitler!
Yours
