Freezing Experiments
to investigate the most effective means of treating persons who had been severely chilled or frozen. The victims were forced to remain in a tank of ice water for up to 3 hours. Extreme rigor developed in a short time. Numerous victims died in the course of these experiments. After the survivors were severely chilled, rewarming was attempted by various means. In another series of experiments, the victims were kept naked outdoors for many hours at temperatures below freezing. The victims screamed with pain as their bodies froze.

Sea-water Experiments
to study various methods of making sea water drinkable. The victims were deprived of all food and given only chemically processed sea water. Such experiments caused great pain and suffering and resulted in serious bodily injury to the victims.

Report by SS-Untersturmführer Rascher about cooling experiments in Dachau, September 10, 1942. ( Trials of War Criminals Before the Nuremberg Military Tribunals - Washington, U.S Govt. Print. Off., 1949-1953, Vol. I, p. 220):

"The experimental subjects were placed in the water, dressed in complete flying uniform, winter or summer combination, and with an aviator's helmet. A life jacket made out of rubber kapok was to prevent submerging. The experiments were carried out at water temperatures varying from from 2.5 to 12 Centigrade. In one experimental series, the occiput (brain stem) protruded above the water, while in another series of experiments the occiput (brain stem) and back of the head were submerged in water.

Electrical measurements gave low temperature readings of 26.4 in the stomach and 26.5 in the rectum. Fatalities occurred only when the brain stem and the back of the head were also chilled. Autopsies of of such fatal cases always revealed large amounts of free blood, up to one-half litter, in the cranial cavity."

Report by Prof. Dr. Holzloehner, Dr. Rascher, and Dr. Finke, regarding cooling experiments, October 10, 1942. (Trials of War Criminals Before the Nuremberg Military Tribunals - Washington, U.S Govt. Print. Off., 1949-1953, Vol. I, p. 226-243):

"If the experimental subject was placed in the water under narcosis, one observed a certain arousing effect. The subject began to groan and made some defensive movements. In a few cases a state of excitation developed. This was especially severe in the cooling of head and neck. But never was a complete cessation of the narcosis observed.

The defensive movements ceased after about 5 minutes. There followed a progressive rigor, which developed especially strongly in the arm musculature; the arms were strongly flexed and pressed to the body. The rigor increased with the continuation of the cooling, now and then interrupted by tonic-clonic twitchings. With still more marked sinking of the body temperature it suddenly ceased. These cases ended fatally, without any successful results from resuscitation efforts."
