 of the better qualities of corn, for instance, in case of the 

 Wheeler's Prolific (I.), has a nutritive ratio approximately 

 equal to 1 : 7.09 ; in case of the Southern White Flint, equal 

 to 1 : 7.23. This ratio is approximately equal to that of the 

 two Western varieties (IX., X.), and also to that of sample 

 VII., Canada Dutton of Sunderland. It means, in practice,

 in case of a good corn as compared with a light corn. 

 Manuring pays in more than one way. 



As it may not be without interest to some to obtain a

 kernel, and the peculiarity of one of its principal constitu- 

 ents, starch, I introduce some drawings of microscopic obser- 

 vations (Sachsse) concerning these subjects.
