We shall now give a tabular extract of the effects of the cold bath, 

 first on the heat of the surface, and afterwards on that of the internal 

 parts.

This Table exemplifies, as was to be expected, that the cold baths 

 considerably cooled the surface of the body, and that the longer the 

 immersion the greater was the depression of the temperature of the skin. 

 Thus this Table shows that on some occasions the temperature of the 

 axilla fell to 87° Eahr. ; but a depression so great occurred only when the 

 bath was continued for a considerable time, for a period, indeed, varying 

 from 15 to 35 minutes ; and even this amount of depression was of short 

 duration. To illustrate this effect we give three extracts from the pre- 

 ceding Table. A bath of 60° Fahr. for one minute reduced the tempe- 

 - rature of a child five years old to 95° Fahr., but in 13 to 25 minutes the 

 temperature of the axilla had nearly recovered itself. "With a bath of 

 the same temperature continued five minutes we reduced the temperature 

 to 92° ; but in 48 to 75 minutes after leaving the bath the axillary tem- 

 perature had nearly recovered. Nay, even after a bath of 35 minutes 

 the temperature only fell to 89°, and recovered itself in 135 minutes. 

 The greater part of the lost heat was very quickly restored, and then the 

 axilla more slowly regained the rest of the lost temperature. 



Influence of Cold Baths on the Temperature of internal parts of the Body. 

 Cold baths reduce the temperature of internal parts of the body, but
