DETERMINATION OF THE AMOUNT OF CARBON 

 EXPIRED. 



1. ANALYSIS or 



Faces. 



2-356 dry faeces left 0-320 ashes (13-58 per cent). 



0-352 dry fseces yielded 0-576 carbonic acid, and 0-218 water. 



Lentils. 



0-566 lentils, dried at 212, yielded 0-910 carbonic acid and 

 0-366 water. 



Pease. 



1-060 pease, dried at 212, left 0-037 ashes. 

 0-416 do. do. yielded 0-642 carbonic acid, and 



0-241 water. 



Potatoes. 



0-443 dried potatoes yielded 0-704 carbonic acid and 0-248 

 water. 



Black Bread (Schwarzbrod). 



302 dried black bread yielded 0-496 carbonic acid and 0-175 

 water. 



0-241 do. 0-393 do. 0-142 



water. 



From the above, which are the direct results of experi- 

 ment, the composition in 100 parts is calculated as in the 

 following table.
