COMPOSITION OF GREEN RYE AND RAPE. 



total proportion of nitrogen was found, in two determinations, on 

 an average, at .442 per cent, equal to 2.762 per cent of protein 

 compounds. 



By separate determinations there were found 



Soluble albumen, . . 1.810 with .289 of nitrogen. 



Insoluble protein compounds, . .894 .143 



2.704 



.432 



The two latter determinations agree well with the total amount 

 of protein compounds, as ascertained by combustion. 



According to these determinations, the general composition of 

 both samples of green rye may be represented as follows : 



Water, .... 



Inorganic matters (ash), 



Nitrogenised substances (flesh-forming con- 

 stituents), .... 



Non-nitrogenised substances (fat and heat- 

 producing matters), . , 



And that of rye in a dry state 



Nitrogenised substances, capable of produc- 

 ing flesh, .... 



Substances free from nitrogen, and fitted to 

 support respiration, and for the forma- 

 tion of fat, . 



Inorganic matters (ash),

It will appear that the first sample, although containing more 

 water, is richer in flesh-forming constituents than the second. In 

 the more succulent condition, rye thus appears to contain especially 

 more soluble albumen than at a more advanced state of maturity ; 

 we may therefore infer from this fact, that it is not a good plan to 

 let the green rye remain too long on the ground before eating it 

 off by sheep.

 mate analyses of both samples of rye, in its natural state and in 

 a perfectly dry state :
