However, the further assertions of the witness Neff suffer from the same shortcomings as those of the witness Vieweg; for Neff also did not know that only part of the high-altitude experiments in Dachau were carried out with the approval of Dr. Ruff and Dr. Romberg; nor did Neff have any knowledge of the agreements made by the participating physicians, and he therefore treated all high-altitude experiments equally, without distinguishing whether or not Dr. Ruff had agreed to them that there “were 180 to 200 inmates who participated in high-altitude experiments” (_German Tr. p. 656_) and that “during the altitude flight experiments, 70 to 80 people lost their lives.” These figures may be correct, but they refer to the whole of the Dachau low-pressure chamber experiments; that is, they also include the experiments which Dr. Rascher made on his own authority, without the prior knowledge of Dr. Ruff, and in which alone all the fatalities occurred; while in the legitimate experiments—that is, those approved by Dr. Ruff—no fatality occurred at all. Of course, Neff could not know all this. As he said himself it was impossible for him to distinguish “from whom the order came for the individual experiment, and in whose interest the experiment was made.” (_German Tr. p. 715._) The same shortcoming is demonstrated by Neff’s testimony with regard to the nationality of the experimental subjects (_German Tr. pp. 656, 657_) and the manner of their “selection”. However, Neff’s testimony does show that the selection of the experimental subjects was carried out in two different ways: For the “_dangerous experiments_” Rascher ordered the subjects through the local headquarters, and they were produced by the SS; they were therefore people condemned to death (_German Tr. p. 663_), for the “_serial experiments_”. On the other hand, and “for most of the other experiments which took place, the people were brought to the experimental station from the blocks, that is, from the camp” (_German Tr. p. 657_) by the block leaders. (_German Tr. p. 663._) These “serial experiments” were obviously the experiments approved by Ruff, and Neff expressly establishes that “_volunteers reported for these experiments_”! (_German Tr. pp. 657, 712._) He even gives the reasons why the prisoners volunteered: As Rascher, and Himmler too, had promised various inmates that, “if they, participated in the experiments, they would be given a better labor assignment”, and as Himmler promised that they might even be released, volunteers reported to Rascher on their own initiative as he went through the camp, without any special efforts being necessary to find volunteers (_German Tr. p. 657_).
