On 17 February, Rascher forwarded his report on the results of the experiment in which animal warmth was used for the rewarming of severely chilled persons. (_1616-PS, Pros. Ex. 105._) In his accompanying letter to Himmler, he informed him that he was conducting dry-cold experiments in Dachau. Thirty experimental subjects had been experimented upon and had been exposed to cold out of doors from 9-14 hours, thereby reducing their body temperature to 27°-29° C. The extremities of the experimental subjects were frozen white. Rascher suggested a large series of experiments in the Auschwitz concentration camp. This place would be suitable for such experimentation because it was colder there, and the spacious open country within the camp “would make the experiments less conspicuous, as the experimental subjects _yell_ when they freeze severely.” [Emphasis supplied.] (_1616-PS, Pros. Ex. 105._) Himmler gave Rascher permission to carry out additional freezing experiments in the concentration camps Auschwitz and Lublin. (_1615-PS, Pros. Ex. 109._) Rascher’s letter to the defendant Rudolf Brandt, dated 4 April 1943, reveals that another series of dry-freezing experiments had been carried out on inmates of the Dachau concentration camp during a period of heavy frost weather. Some of the experimental subjects were exposed to cold of -6° C. in the open air for 14 hours and had reached an internal temperature of 25° C. (_NO-292, Pros. Ex. 111._) The three fatalities which, according to Neff’s testimony, resulted from the dry-freezing experiments, apparently occurred during this series of experiments. (_Tr. pp. 637-8._) On 11 April 1943, Rascher submitted to Himmler a brief report concerning “freezing experiments on human beings exposed to the open air.” (_NO-240, Pros. Ex. 112._) The report itself is not available, but the letter of the defendant Rudolf Brandt of 16 April to Rascher proves that the defendant Gebhardt received it from Himmler for study. (_NO-241, Pros. Ex. 113._) A conference between Rascher and the defendant Gebhardt took place in Hohenlychen on 14 May in the presence of the defendant Fischer. Gebhardt discussed with Rascher the freezing experiments and other experimentation carried out in the Dachau concentration camp and invited Rascher to collaborate with him. Rascher feared to lose his independence and turned to Sievers to settle this affair in a tactful way as Gebhardt was a very close friend of Himmler, and Rascher, therefore, feared his eventual enmity. (_NO-231, Pros. Ex. 116._) Sievers, in turn, approached Brandt in this matter on 22 May and requested information whether Himmler had given any definite directive to Gebhardt in regard to Rascher’s sphere of action and work. He further asked Brandt’s intervention on behalf of Rascher by saying:
