INORGANIC ANALYSES OF THE SEVERAL PARTS OF THE PLANTS OF THE 
EARLY WHITE FLINT CORN, AT DIFFERENT STAGES OF THEIR GROWTH. 
The dates on which the plants were taken for analysis, correspond with those on which 
they were taken for proportions. I have hence, to save repetition, omitted to give descrip¬ 
tions of the stage of advancement of the plants with the following analyses, as these are 
given in full in connection with the proportions, and can be easily referred to. 
It would have been desirable to have made this series of analyses more complete ; but 
the plant was divided into so many parts, that it was quite impossible for one to do it, and 
carry on organic analyses of the same parts at the same time. Considerable, however, 
has been done. The analyses were conducted during several successive weeks, when the 
plants were growing most vigorously. They were also analyzed after they had ripened 
their grain. The roots were freed of foreign matter, by washing them carefully in cold 
water. The potash was obtained with bichloride of platinum. It is proper to state this 
here, inasmuch as by this process less potash has been obtained, and of course more soda 
than by absolute alcohol. Both methods have been followed at different times; but in 
this series, the bichloride of platinum has been exclusively resorted to for separating the 
two alkalies.
