2-4; boxings, 3-6; and bran, 3*3 percent. Dumas states 

 that the husk of oats sometimes yields as much as five or 

 six per cent, of oil." The columns under starch, &c., 

 and fatty matter, denote the value for respiration or sus- 

 taining life and the fattening qualities ; that under gluten, 

 the capacity for yielding muscle and supporting labor ; and 

 saline matter indicates something of the proportions which 

 are capable of being converted into bones.

This table, it will be perceived, is far from settling the 

 precise relative value of the different enumerated articles. 

 An absolute, unchanging value can never be assumed of any 

 ono substance, as the quality of each must differ with the 

 particular variety, the soil upon which it is grown, the cha- 

 racter of the season, the manner of curing, and other cir- 

 cumstances. An approximate relative value is all that can 

 be expected, and this we may hope ere long to obtain, from 

 the spirit of analytical research which is now developed and 

 in successful progress. More especially do we need these 

 investigations with American products, some of which are but 

 partially cultivated in Europe, whence we derive most of our 

 analyses. And many which are there reared, differ widely 

 from those produced here, as these also differ from ench 

 other. What, for instance, is the character of meadow hay ?
