DETERMINATION OF THE AMOUNT OF CARBON 



EXPIRED. 



1. Analysis of 



. ' FcEces, 



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



0-352 dry feces 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. 



JBlack Bread (Schwarzbrod). 



0*302 dried black bread yielded 0*496 carbonic acid, and 0*175 

 water. 



0*241 do. 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.
