Table VI. Artificial Grasses. Name, and Date of Collection. 



The inquiries of Prof. Way -were directed to ascertain 



1. The proportion of water in each grass as taken from tlie 

 field. 



2. The proportion of albuminous or flesh-forming substances, 

 including, without distinction, all the nitrogenous principles. 



3. The proportion of oily or fatty matters which may be 

 called fat-forming principles. 



4. The proportion of elements of respiration, or heat pro- 

 ducing principles, among which are included starch, gum, 

 sugar, pectic acid, &c. ; all the non-nitrogenous substances 

 indeed, except fatty matters and woody fibre. 



5. The proportion of woody fibre. 



6. The amount of mineral matter or ash. 



The specimens were picked out, plant by plant, each specimen 

 by itself, from fields in which they were growing naturally, or 

 mixed in the ordinary mode of cultivation, and were not raised 

 expressly for analysis. 



These tables of analyses, containing as they do the results of 

 profound investigation, and forming as they do one of the most 

 important contributions recently made to the science of agri- 

 culture, are worthy of careful study and will be found to be 

 full of the most valuable practical suggestions. 



Tlie results of the analysis of the natural grasses in the green 

 state, are arranged in table VII. as follows : —
