many cases more than double) of albuminous matters, and of a 

 certain, though less evident, advantage in the quantity of fatty 

 matters; whilst the heat-giving principles remaining nearly the 

 same, the quantity of woody matter is necessarily much reduced. 

 As a proof of the high value which theoretically we should place 

 upon the artificial grasses, I may remark that in the dry state 

 they equal peas or beans in nitrogenous matter, and considerably 

 excel them in the proportion of fatty matter. 



" I will take leave of these tables by remarking that, if the view 

 which gives a prominent value, for feeding purposes, to albumi- 

 nous matters in large proportion over the non-nitrogenous por- 

 tions of plants be correct, the " artificial " are far more nutritive 

 than the natural grasses. But, as I before said, these results 

 were not intended as a peg to hang an argument upon, either on 

 one side or the other, and for the present I am content to ofter 

 them as a contribution to the Chemistry of Vegetation, without 

 further argument or deduction.
