MAIZE. 



Indian corn contains about the same proportion of starch as 

 oats (sixty per cent.), but is more fattening, as it contains about 

 nine or ten per cent, of oily or fatty ingredients. 



The following analysis of maize is given by Dr. Samuel David, 

 of Massachusetts : 



FLESH FORMING PRINCIPLES. 



Gluten, albumen, and casein . 



FAT FORMING PRINCIPLES. 



Gum, sugar, starch, woody fibre, oil, &c. 

 Water ......

Professor Johnston supplies a table, which, he says, exhibits the 

 best approximate view we are yet able to give of the average pro- 

 portion of starch and gluten contained in 100 Ibs. of our common- 

 grain crops as they are met with in the market. 



Prom this table I extract the following : 



Wheat flour. . 

 Oats 



Indian corn 

 Beans . 

 Peas . 

 Potatoes 



The Professor remarks that the proportion of oil is, in 100 Ibs. of 

 Wheat flour 



Oats . 

 Indian corn 

 Beans and peas .
