the application of heat should be gradual, the former (Beck, Hor- 
wat, Jacoby) advise that it should be rapid. The author has ex¬ 
perimented with dogs in order to solve this question. Some of 
the animals were exposed to cold air (—17° C., two above zero 
F.), others were packed in freezing mixtures (13-15° C., 5-8° F.). 
After freezing, one of the animals (twenty experiments were 
made, each with three dogs) was immediately placed in a warm 
bath of 37° f£. (115° F.); the second was placed in a room the 
temperature of which was 22 24° B. (81-86° F.); the third was 
first placed in a temperature of 0° (32° F.), and then, as the tem¬ 
perature of the rectum rose and manifestations of life were 
shown, the bodily temperature increased. Friction with brushes 
and dry cloths was used in all three cases. 
The experiments, which were made with great care, throw 
light on various conditions which will not be referred to here 
(blood examinations, microscopic examinations of the muscular 
tissue, conditions of temperature, etc.). But there were other re¬ 
sults which have a practical significance for physicians. Of 20 
animals that were exposed to a low temperature which was gradu¬ 
ally elevated, 14 died; of 20 animals that were immediately 
brought into a warm apartment. 8 died; of 50 animals that were 
immediately placed in a warm bath, none died .—Medical Record .
