character, nor due to errors of analysis. Summarized these differences 

 are as follows: air-dry sweet corn in general carries less moisture than 

 dent corn, sweet corn in general has a higher percentage of protein, 

 fat, ash and fiber than does dent corn in general. On the other hand 

 dent corn in general has a higher content of starch and other carbo- 

 hydrates with the exception of fiber and the sugars than does sweet. 

 We may now consider the results regarding the inheritance of 

 chemical characters in maize which appear to flow from the data set 

 forth in Tables I and II. 



Pi Generation. 



In general it may be said that the Fj kernels resemble most 

 closely the dent parent in their chemical characters. In other words 



') Analysis I represents the average of all analyses of dent varieties of maize 

 by Jenkins and Winton (7) p. 95. Analysis la represents the average of all analyses 

 of sweet varieties compiled by the same authors (p. 99). 



2) Analysis II and IIa are taken from Wiley (8) who gives them on the 

 authority of König. II represents the analysis of 149 samples of dent maize and IIa 

 the analysis of 27 samples of "sugar corn". 



') .-Xnalysis III gives the mean result from 41 samples of sweet corn tabled by 

 Straughn (6). The means in Table III are our own calculations from Straughn's 

 figures, since that author gives average figures on a water free basis only.
