“_8 Mar-18 Mar 1944_: It is suggested by Colonel of this air corps, Prof. Rose, the vaccine ‘Kopenhagen’, produced from mouse liver by the National Serum Institute in Kopenhagen, be tested for its compatibility on humans. Twenty persons were vaccinated for immunization by intramuscular injection. * * * Ten persons were contemplated for control and comparison. “_16 Apr 1944_: The remaining experimental persons were infected on 16 April by subcutaneous injection of 1/20 cc. typhus sick fresh blood. The following feel sick: 17 persons immunized: 9 medium, 8 seriously. Nine persons from the control: 2 medium, 7 seriously. “_13 Jun 1944_: Chart and case history completed and sent to Berlin. Six deaths (3 ‘Kopenhagen’) (3 control). “_4 Nov 1944_: Chart and case history completed. Twenty-four deaths.” Copies of each of Dr. Ding’s official reports went to the defendants Mrugowsky and Poppendick as well as to the I. G. Farben laboratories at Hoechst. Nowhere will the evidence in this case reveal a more wicked and murderous course of conduct by men who claimed to practice the healing art than in the entries of Dr. Ding’s diary relating to the typhus experiments. K. Poison Experiments Here again the defendants were studying how to kill, and the scene is Buchenwald. Poisons were administered to Russian prisoners of war in their food, and German doctors stood behind a curtain to watch the reactions of the prisoners. Some of the Russians died immediately, and the survivors were killed in order to permit autopsies. The defendant Mrugowsky, in a letter written in September 1944, has provided us with a record of another experiment in which the victims were shot with poisoned bullets, and I quote (_NO-201_): “In the presence of SS Sturmbannfuehrer Dr. Ding, Dr. Widmann and the undersigned, experiments with aconitin nitrate projectiles were conducted on 11 September 1944 on 5 persons who had been condemned to death. The projectiles in question were of a 7.65 mm. caliber, filled with crystallized poison. The experimental subjects, in a lying position, were each shot in the upper part of the left thigh. The thighs of two of them were cleanly shot through. Afterwards, no effect of the poison was to be observed. These two experimental subjects were therefore exempted. * * * * *
