" The greater richness of sweet corn in albuminoids and 

 fat is very decided and indicates a higher nutritive vahie 

 than that of common corn. 



" The sweet corn contained on the average 8.6 per cent. 

 of water, and the common contained 10.8 per cent., but 

 the samples were unequally dried, and the analyses prob- 

 ably do not show the proportions of water that exist in corn 

 in bulk as found in the crib or in market. 



"The range of variation in the several ingredients is 

 shown by the following statement of the lowest ^nd high- 

 est percentages as found in these analyses :"
