NOTE (16,) a, p. 30. 



AMOUNT OF CARBON IN FLESH AND IN STARCH. 



100 parts of starch contain 44 of carbon ; therefore, 64 oz. (4 Ibs.) contain 28-16 oz. of 

 carbon. 



100 parts of fresh meat contain 13-6 of carbon (see Note III.;) hence 240 oz. (15 

 contain 32-64 oz. of carbon.* 



* By an error in calculation in the original, the amount of carbon in 15 Ibs. of meat is stated to be 

 27'64 oz. It follows, that the carbon of 4 Ibs. of starch is not equal, as stated in the text, to that of 

 15 Ibs. of flesh, but to that of 13 Ibs. This difference, however, is not sufficient to affect the argu 

 went at p. 32. EDITOR.
