_C. Type of experimental subjects._
1. _F 1001._ The documents submitted do not reveal the nature of the
experimental subjects, though the year 1939 indicates that in no case
were foreigners used.
2. _“Lost”._ According to Sievers’ testimony, the persons used in the
experiments in the Natzweiler concentration camp volunteered, so that
the nature of the experimental subjects would appear to be of no
significance as a basis for judgment. The testimony of the defendant
Rudolf Brandt (_NO-372, Pros. Ex. 252_) is no basis to judge the true
state of affairs, as Rudolf Brandt’s testimony (_Tr. pp. 4930-34_) shows
that he himself never witnessed an experiment and that his statements
are conclusions drawn from documents and statements submitted by the
interrogators.
