All these experiments having been made on one person, I determined to re- 

 peat this last on another. 



Exper. 5. R. Sutton, ast. ig, of a pale complexion, and a feebler frame, was 

 immersed in the bath, under the circumstances of the preceding experiment. 

 His heat was previously y6°-i-.

Though this person seemed to bear the cold bath well, having lost in SC" 

 only 1\ degrees of heat, yet when exposed afterwards to the wind, he shivered 

 violently, and lost his heat very fast. He was put into a warm bath, heated to 

 96°, but recovered his heat very slowly, as the following table will show.

Exper. 6. Richd. Edwards, the original subject of experiment, was again im- 

 mersed in the cold bath, of the temperature of 40°, and remained in it a of an 

 hour. His heat previously was 97°; his pulse 90 in the minute. The mercury 

 fell to 92°, was stationary for a kw minutes, and then mounted, though as usual, 

 with no regularity. In I'l"" it stood at 96°; it then began to decline, and in 23"" 

 more had sunk to 94°. Being exposed as usual to the wind, the mercury sunk 

 as usual, and he shivered violently. In the warm bath at 96° his shiverings con- 

 tinued several minutes, his heat remaining at 90 and 91°. In 7 minutes the 

 mercury began to rise fast, and 5 minutes after was at 96°. 



Exper. 7. The effects of 45"" iinmersion in the cold salt-water bath, at 40°, 

 were projjosed to be tried on Richard Sutton. He was much under the im- 

 jjressions of fear, and his heat previously raised the mercury only to 94°. The
