The young heather shoots contain a good deal more water and 

 less fibre, resinous matter, and other constituents than the iQore 

 mature parts of the plant : they are less nitrogenous than most 

 of the other foods : in the dry matter they contain less nitro- 

 genous matter than any of the foods noticed, and less than half 

 that of the Carices and Molinia. They are particularly rich in 

 matters soluble in ether, more than 8 per cent, of the dry 

 matter being so soluble. The indigestible fibre in them is lower, 

 and the digestible non-nitrogenous matter higher than in the 

 other foods. 



The percentage of water in the mafe grass is much lower 

 than in the other fodders, and consequently the fibre and non- 

 nitrogenous extractive matter higher. The Molinia is richer in 

 nitrogenous matter than most grasses ; the two species of Carex 

 examined are also particularly rich in nitrogenous matter, about 

 20 per cent, of the dry matter of each of these three consisting of 

 nitroojenous substance. The draw^-moss contained less nitrosjen 

 than the other Cyperacece,h\x\j nearly the whole of it was albuminoid.
