Parsnip and White Belgian Carrot. 



cutting the whole root into slices, which, on bein<^ dried, are 

 powdered together. A fair average sample of the whole part is 

 thus obtained for analysis, and all errors, arising from the want 

 of uniformity of distribution of the albuminous matters in root-^ 

 crops, are thereby avoided. 



II. Composition of the White Belgian Carrot, 

 a. Carrots grown in 



Water. — 1. Dried in the water-bath fresh carrots lost 88*06 

 per cent, of water. 



2. In a second determination 88'47 per cent, of water were 

 found. On an average carrots thus contain 88 26 per cent, of 

 water. 



Ash. — 1. 100 parts of fresh carrots were found to contain 0*74- 

 per cent, of ash. In the dried state, accordingly, they contain 

 6*22 per cent, of ash. 



2. In a second determination the percentage of ash in fresh car- 

 rots was ascertained to be 0*75, or in dried roots 6*56. On an ave- 

 rage fresh carrots thus contain 0'74 per cent., and in the dried 

 state 6'29 per cent, of ash. 



Protein Compounds. — 12*81 grains of dry caiTots burned with 

 soda-lime gave 1*66 grains of chloride of platinum and ammo- 

 nium. 100 parts of fresh carrots accordingly contained 0*095 of 

 nitrogen, equal to 0*596 of protein compounds ; and in the dried 

 state 0*813 of nitrogen, equal to 5*081 of protein compounds. 

 According to the^e determinations the general composition of 

 fresh carrots grown in 1851 may be represented as follows : —
