subject of common insistence. How the damp increases the con- 

 ductivity is shown by the following observation. An arm clothed 

 in dry flannel and enclosed in a calorimeter lost 4-5 Cal. in an 

 hour; when the flannel was wet the loss rose to 22'7 Cal., an 

 increase of 344 per cent. 



The Japanese have especially acquired the liking for very 

 hot baths. But they sit with head and most parts of their 

 limbs out of the water. The writer found a Japanese gentleman 

 stand a bath of 44- 5 C. (114 F.) for a few minutes while totally 

 immersed except for his head and neck. His body temperature 

 rose to 39-5 C. (103 F.). A man in a hot bath sweats as much 

 as in hot air, as may be determined by the amount of sodium 

 chloride he adds to the bath (Spitta). Prolonged immersion in 

 a cold bath at 25 C. increases the 2 use from 21 to 37 grm. 

 per hr. (Zuntz).
