208 Dr. Currie's Account of the 
He was now taken out, and stood in the wind three mi- 
nutes, shivering violently. This circumstance rendered it dif- 
ficult to ascertain exactly the fall of the mercury, which was, 
however, considerable. When examined in the room in which 
he undressed, it stood at 90°. He was now plunged into a 
fresh-water warm bath, heated to 97°^. What is very sur- 
prising, the mercury fell two degrees. The following table 
will show the progress of the return of his heat.

If the rise of heat in the cold bath at 44 0 , and the warm 
bath at 97°^-, be compared, the first will be found more slow; 
but that after being sixteen minutes in the one and in the 
other, the heat was the same in both cases, when taken at the 
mouth. It must, however, be acknowledged, that in the cold 
bath, the extremities were chilled and cold, while in the hot 
bath, the heat was equally diffused. When Edwards got out 
of the hot bath, he put on his clothes, and was remarkably 
alert and cheerful the whole evening. Encouraged by the 
safety of these experiments, I resolved to increase the time of 
immersion in the cold bath, and to inquire more generally into 
its effects on the sensations, as well as heat. 
EXPERIMENT IV. 
At the same hour of another day, the same person was again 
immersed as before, his heat previously being 97°f, and that 
of the water 42 0 . Wind north-east, and brisk.
