ANALYSES OF THE OAT. 93 



The ash of the chaff amounts to - 3 '56 per centum; 

 And of water to - - - - 7 '00. 



The chaff, from its thinness, is usually well dried in the sun, though it seems to absorb 

 moisture from the atmosphere. These specimens had been exposed to the dry air of the 

 heated room for some time previous to their analysis.
