ries very greatly in its inorganic constituents. But we are led 

 to believe that it varies still more in Europe, if Liebig (AgricuL 

 Chem.,) is correct in stating : &quot; There are certain plants which 

 contain either no potash or mere traces of it. Such is Indian 

 Corn. (Zea mays.) For plants such as these the potash in 

 the soil is of no use, and farmers are well aware that they can 

 be cultivated without rotation on the same soil.&quot; 



The water in dry corn varies from 10 to 15 per cent.; but as 

 high as 37 per cent, when first ripened. 



282. Organic analysis of various varieties of corn grown in 

 New York. (Salisbury.) Golden Sioux corn, 1 2, 14-rowed, 

 an improved variety of Buell s Dutton corn (A,) Ohio Dent 

 corn (B,) small 8-rowed corn (C,) White Flint, grown on clay 

 loam, and manured with coal ashes, horse dung, and unleached 

 wood ashes (D,) large 8-rowecl yellow com (E.) 



When the dough of Indian corn is washed with water, a 

 glutinous residue is left different from the gluten of wheat, and 

 characterized by its solubility in alcohol, and therefore altered to 

 vegetable gelatin. 



The organic composition of corn in Europe differs from the 

 above according to the following analyses. (Knapp and
