ANALYTICAL EVIDENCE. 275 



tains both fat and cellular tissue, which together amount to 

 fth of the weight of the meat as bought from the butcher. 

 The number of ounces consumed (by 855 men) was 4,448, 

 consisting, therefore, of 



3812-5 oz. of flesh, free from fat, containing 1 of carbon 518*5 oz. 

 635-5 oz. of fat and cellular tissue, ditto 449-0 oz. 



4448-0 oz. In all, carbon 967-5 oz. 



With the bones, the meat, as purchased, contains 29 

 per cent, of fixed matter, including bones ; 4,448 oz. of 

 flesh, therefore, contain 448 oz. of dry bones. These have 

 not been included in the calculation, although, when 

 boiled, they yield from 8 to 10 per cent, of gelatine, which 

 is taken as food in the soup. 



Fat. The amount of fat consumed was 56 oz. ; which, 

 the carbon being calculated at 80 per cent., contain in all 

 44'8 oz. of carbon. 



Lentils, pease, and beans. There were consumed 53 '5 

 oz. of lentils, 185'5 oz. of pease, and 218 oz.f of beans. 

 Assuming the average amount of carbon in these vegeta- 

 bles to be 37 per cent., the total quantity of carbon con- 

 sumed in this form was 169-1 oz. 



Potatoes. 100 parts of fresh potatoes contain 12'2 

 parts of carbon. In the 15,876 oz. of potatoes consumed, 

 therefore, the amount of carbon was 1936-87 oz. 



Bread. 855 men eat daily 855 times 32 oz., besides 

 36 Ibs. of bread in the soup, which in all amounts to 

 27,936 oz. 100 oz. of fresh bread contain, on an average, 

 30-15 oz. of carbon ; consequently, the carbon consumed 

 in the bread amounts to 8771-5 oz. 



t According to the table, 222 oz.
