210 On the Temperature of the Human Body in Health. 



Here it was impossible that the heat which raised the temperature of 

 the body could be obtained from the bath, itself never hotter than 

 the bodies of the boys before undergoing the experiment. If the for- 

 mation of heat was lessened so as exactly to meet the diminished loss by 

 conduction and radiation, the heat of the body would have continued at 

 the same point ; but this was not the case, and thus it appears that the 

 formation of heat cannot be suddenly lessened to such an amount. 



Thus the increased heat of the body ensuing from a vapour-bath is 

 certainly in part due to accumulation of heat, which under other cir- 

 cumstances is lost by evaporation and radiation. Is all the heat imparted 

 to the body by the vapour-bath to be accounted for in this way ? Some 

 part must, in the nature of things, be absorbed from the bath, and is 

 evidenced in our experiments, the elevation being too rapid to be caused 

 solely by an accumulation of heat in the body.
