ANALYSIS OF HAY. 



100 parts of hay dried in the air contain 86 of dry matter, 



14 of water. 



100 



100 parts of hay dried at 212 = 116-2 parts dried in 

 air, contain 



Carbon 45'8 



Hydrogen 5'0 



Oxygen 38'7 



Nitrogen T5 



Ashes 9'0 



100-0 

 16. 2 water, 



11 6' 2 hay dried in the air. 



100-0 of hay dried at the ordinary temperature contain T29 

 of nitrogen. 

 240 oz. of such hay = 15 Ibs. contain ... 3-095 oz. of nitrogen. 



72 oz. of oats = 4 Ibs. contain ... T34 ditto 



Total .. .. 4-435 ditto 



NOTE (16), a, p. 77. 



AMOUNT OF CARBON IN FLESH AND IN STARCH. 



1 00 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 Ibs.) contain 32-64 oz. of 

 carbon.^ 



J By an error in calculation in the original, the amount of carbon in 15 Ibs. of 

 meat is stated to be 27'64oz. It follows, that the carbon of 41bs. 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 argument at p. 84.
