cereals. A relatively large part of the protein matter of these seeds is 

 readily soluble in alcohol of 70 to 80 per cent, by volume, while zein can be 

 dissolved in all proportions by strong commercial alcohol of 92 to 94 per cent. 

 Proteins of similar solubility have as yet been found in no other tissues of 

 either vegetable or animal origin. All these proteins differ from other 

 proteins thus far studied in yielding no lysine. All of them yield relatively
