DETERMINATION OF THE AMOUNT OF CARBON 

 EXPIRED. 



1. ANALYSIS OF 



FcBces. 



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

 0-352 dry fzeces 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). 



0-302 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.
