In the hope that you, highly esteemed Reich Leader, will be able to spare a quarter of an hour to listen to an oral report, I remain, with the most obedient regards and Heil Hitler! Yours respectfully. [Signed] S. RASCHER. PARTIAL TRANSLATION OF DOCUMENT NO-428 PROSECUTION EXHIBIT 91 REPORT OF 10 OCTOBER 1942, ON COOLING EXPERIMENTS ON HUMAN BEINGS STABSARZT PROF. DR. E. HOLZLOEHNER STABSARZT DR. S. RASCHER STABSARZT DR. E. FINKE _I. Problem of the Experiment_ Up to the present time there has been no basis for the treatment of shipwrecked persons who have been exposed for long periods of time to low-water temperatures. These uncertainties extended to the possible physical and pharmacological methods of attack. It was not clear, for example, whether those who had been rescued should be warmed quickly or slowly. According to the current instructions for treating frozen people, a slow warming up seemed to be indicated. Certain theoretical considerations could be adduced for a slow warming. Well-founded suggestions were missing for a promising medicinal therapy. All these uncertainties rested in the last analysis upon the absence of well-founded concepts concerning the cause of death by cold in human beings. In the meantime, in order to clarify this question, a series of animal experiments were started. And, indeed, these officials who wished to make definite suggestions to the doctors in the sea-rescue service had to assume a great deal of responsibility if it came to a question of convincing and consistent results in these animal experiments. At this particular point it is especially difficult to carry the findings in animals over into the human field. In the warm-blooded, one finds a varied degree of development in the heat-regulating mechanism. Besides this, the processes in the skin of the pelted animals cannot be carried over to man. _II. General Procedure of the Experiment_ The effect of _water temperatures_ of 2°, 3°, to 12° C. [34°, 37°, to 54° F.] were investigated. A tank 2×2×2 m. [6-2/3×6-2/3×6-2/3 ft.] served as an _experimental basin_. The water temperature was attained by addition of ice, and remained constant during the experiment. The experimental subjects were generally dressed in _equipment_ such as the flier wears, consisting of underclothing, uniform, a one piece summer or winter protective suit, helmet, and aviators fur-lined boots. In addition they wore a life preserver of rubber or kapok. The effect of _additional protective clothing_ against water-cold was tested in a special series of experiments, and in another series the _cooling of the unclothed person_ was studied.
