If anything, the proportion of woody stems is rather over than 

 under estimated, for, as stated, only 6 inches of the top were cut 

 off; I think it likely, therefore, that some of the woody stems 

 would be eaten by sheep or cattle. 



A water-determination of the green lupine plants gave 89*20 

 per cent., and an ash-determination, 80 per cent, of ash on an 

 average. 



The amount of nitrogen in the green plants was found to be 

 38 per cent. Accordingly lupine plants, cut down green, con-

In cabbages analysed last year I found the average proportion 

 of water 89*5 per cent. There is thus about as much water in 

 lupines, cut down green, as in the cabbages, the analysis of which 

 I published some time ago ; the amount of mineral matter is 

 likewise nearly the same in both, but the proportion of albu- 

 minous or flesh-forming matter is more considerable than in 

 cabbages. 



The greater portion of the dry matter in lupines I found in- 

 soluble in water, as will be seen by the following results, repre- 

 senting the general composition and proportion of juice and crude 

 fibre in the plants analysed in my laboratory :
