rated from the pods and weighed apart. The weight in grain 

 of the different parts of a hundred plants was — 



Roots, 



Stalks, 



Leaves, 



Pods, 



Beans, 



Giving for the weight in lbs. per acre :-

Owing to the decayed condition of the leaves, it appeared 

 inadvisable to attempt their proximate analysis, which would 

 only have led to erroneous results, but they were burned, and 

 the composition of the ash determined. The proportion of the 

 different constituents of the other parts were as follows : — 



Water, 



Albuminous compounds, 

 Other organic matters, 

 Ash, . 



Nitrogen, 



Roots.
