Payen found 1.11 percent of nitrogen in dry beet, of which one-third 

 teas due to the albumen. Horsford, obtained from beet-root, which 

 lost in drying 82 1 4 per cent of water, 1.8 per cent of nitrogen. Under 

 the very probable supposition that all these nitrogenous substances are 

 of an alhurninous nature, these nnmbers would correspond with 11.54 

 per cent of albuminous matters, or 6.16 per cent of the amount of sugar.

As will be noticed above, Chloride of Sodium (common salt) enters 

 largely into the composition of the Mangold. Prof. Way gives the fol 

 lowing comparative table of the quantity of salt yielded by one ton of 

 each of these plants :
