I place the analysis of a sample of the ash of Kleinwanzle- 
hener beets, carrying 14.7 per cent, sugar, together with that of the 
ash of its leaves, side by side with that of a French beet, supposed 
to carry 15 per cent, sugar, and its leaves :

In considering the effect of the soil, particularly of the alkali, 
upon the percentage of sugar, I adopted, as a standard of compari- 
son, beets grown upon two other plots of ground, free from alkali, 
and in good tilth. In this case the meteorologic conditions were the 
same in every respect, and it was simply a question of soil. The 
same was true in regard to the feeding value, of both the roots and the 
leaves; with the constituents of the ash, which are obtained wholly 
from the soil, the question is not so simple, for there is an uncertainty 
in regard to the measure in which one constituent may replace an- 
other in the economy of the plant, and also in regard to the con- 
ditions which influence the replacement of one compound by an- 
other. 
Some points are so evident, regarding the composition of the 
ashes from my plot, i. e., that the sulphuric acid is very constant at 
about 3 per cent., and that the magnesia and lime are also nearly 
constant, that a multiplication of analyses had no object. In the 
series of samples, taken September 2, we have for the magnesia, in 
the samples taken from the three sections, 4.48 per cent., 4.10 per 
cent., and 4.47 per cent., and for the lime we have 1.74 per cent.,
