From this is calculated the weight per acre of each of these 

 constituents contained in the different parts of the plant, which 

 is as follows : — 



Water, . 



Albuminous compounds, 

 Other organic matters, 

 Ash, . . , 



Nitrogen,

In this stage as during the last, the weight of the flowers 

 and pods was too small to admit of a complete analysis of their 

 ash. They were, therefore mixed with the leaves, and the whole 

 burnt, so that we have again the analysis of the ash in two 

 parts ; stalks and leaves including flowers and pods. The re- 

 sults were : — 



100-83 



101-57 



And after deduction of carbonic acid, sand, and charcoal, 



these gave :- 



Peroxide of Iron, 

 Lime, 

 Magnesia, 

 Chloride of Sodium, 

 Soda, 

 Potash, 



Sulphuric Acid, 

 Phosphoric Acid, 

 Silicic Acid,
