Water of Respiration. 



437 



While with food experiment No. 70, the proportion of water eliminated from 

 the lungs is somewhat less than during fasting, with experiments Nos. 72, 74, 

 and 76, very little, if any, difference is noted. On the average, about 44 per 

 cent of the water vaporized from the body of a resting man during fasting is 



from the lungs.

 from the lungs and skin, respectively, in metabolism experiments with and 

 without food.
