PHASEOLUS VULGARIS (fREXCII BEAN)

The embryos are very rich in nitrogenous matter, the 

 proportion being as high as 44*5 per cent. 



The composition of the husks is very variable, and gives 

 limits of 4' I to ly'S per cent, for nitrogenous matter; 

 similarlv, the differences as regards celhilose are sufficiently 

 large in the different varieties.

All beans, from whatever country, have a nearly identical 

 nutritive value. They are a most valuable food, eaten in the 

 form of meal or of dry seeds. 



The proportions of phosphorus and sulphur contained in 

 these seeds differ according to the varietv ; we express them in 

 phosphoric and sulphuric acid.

These are for peas in the dry state. 



After numerous experiments, M. Balland concludes that 

 phosphoric acid in beans may amount to 1-35 per cent, in the 

 normal state and r65 per cent, in the dry state, and sulphuric 

 acid to o'55 per cent., as in beans from Mavotte.
