Abstract

After freezing rats in both hind extremities with liquid air, investigation was made of changes which took place in the weight, dry material and fluid content of the organs. 1. There was a loss in the total weight of the lungs (44%), liver (39.4%), gastro-intestinal tract (14.2%) and heart muscle (17.8%), and an increase in weight only in the injured limbs (of 28.8%). The weight of the brain, spleen, kidneys and corpus remained unchanged. 2. In dry material the liver lost 36.7% and the heart 12.8%. 3. Greatest loss of fluid content was in the lungs (49.1%) and liver (40%); less in the gastro-intestinal tract (20%) and heart (17.5%). There was no change whatsoever in fluid content of the brain and spleen. The fluid content of thie frozen limbs was 27.4% of the original weight, 43.4% of the original fluid content.
