The results of Aubert which have been given above show that the 
cutaneous respiration varies in intensity in different parts of the body, 
and that for this reason it is impossible to correctly calculate the 
cutaneous respiration of the whole body from the data obtained on one 
limited part, such as the hand. Further, the exchange of gases from the
