Rascher refused to use one of the four women for experiments in rewarming through body heat because this woman possessed beyond doubt the characteristics of the Nordic race. Rascher reported this to the camp commander and to the adjutant of the Reich Leader SS. (_NO-323, Pros. Ex. 94._) In this connection, too, Sievers did not play any part. The prosecution furthermore accuses Sievers of taking part in Dr. Rascher’s dry-freezing experiments [Trockenkaelteversuche]. Sievers is not mentioned in the following documents submitted in this connection: NO-319, Pros. Ex. 96; 1579-PS, Pros. Ex. 97; NO-431, Pros. Ex. 99; 1580-PS, Pros. Ex. 107; 1615-PS, Pros. Ex. 109; NO-292, Pros. Ex. 111; NO-240, Pros. Ex. 112; NO-241, Pros. Ex. 113; NO-432, Pros. Ex. 119. These letters are neither addressed to him nor signed by him. Neither have copies of them reached him nor have they passed through his hands. The letter, dated 12 January 1943, from the Reichsgeschaeftsfuehrer of Ahnenerbe to SS Obergruppenfuehrer Wolff, contains the following passage: “Since the freezing experiments depend on the season, valuable time is lost as long as Dr. Rascher is not available.” (_NO-236, Pros. Ex. 101._) The witness Neff did not testify that Sievers knew of the dry-freezing experiments [Trockenkaelteversuche]. Sievers knew through Himmler’s order of 13 December 1942, that Rascher was supposed to carry out dry-freezing experiments. (_1612-PS, Pros. Ex. 79._) Only during this trial did Sievers come to know that Rascher carried out such experiments in Dachau. Himmler had ordered these experiments to be carried out on the terrain of Berghaus Sudelfeld. They were planned for the winter of 1943-44. Sievers faked inquiries as a result of which the terrain at Sudelfeld was supposed to be unsuited and by this he succeeded in not having the dry-freezing experiments carried out during the winter of 1943-44. The experiments, which Himmler then ordered for the winter of 1944-45, did not take place because Rascher was arrested in the spring of 1944. (_German Tr. pp. 5689-90._) Since the dry-freezing experiments in the mountains, ordered by Himmler, did not take place at all, Sievers can rightfully claim to have helped to prevent them.
