REPORT OF THE COMMISSIONER OF AGRICULTURE. 



As has been said in Table I, the nitrogen has been all stated as albu-, 

 minoid. This has been done merely to carry out the comparison between 

 these analyses and others made previously. 



A more correct way to state them, and one which every one can apply 

 for himself, is to deduct from the all3uminoids an amount cori'esponding 

 to the nitrogen soluble, to deduct, from the sugar extract a like amount 

 and insert the same in the analysis as soluble nitrogen multix)lied by 

 some suitable factor. 



As an example, the analysis of Vicia sativa will serve : 



Moisture 11. 12 



Ash 8.00 



Etlier extract , 4.70 



Resin 1.99 



Sugars. 11.79 



Soluble N. X 6.25 8.57 



Gum 5.96 



Starch isomers 14.20 



Undetermined 2.63 



Crude fiber 13.54 



InsolubleN. X 6.25 17.50 



100. 00 



With the aid of Table II this method of statement can be easily ap- 

 plied to any of the plants analyzed. 



Oscar Kellner * has lately published some results of the determinations 

 of the amide nitrogen at various stages of the growth of grasses, which 

 are given in the following table :
