H 
ACTION OF LIME AS A MANURE. 
Calculating now from these figures how much organic 
matter and combined water was contained in the mixtures at 
the various periods of their examination for every ioo parts 
of mineral matter free from carbon dioxide, we get the 
following figures :

The slaked lime contained, as the analysis given for it 
shows, some carbon dioxide besides combined water, but in 
all the above calculations of the dry matter, and organic 
matter and combined water, it was reckoned only as calcium 
oxide (CaO), because in the mixtures the combined water 
is soon liberated in the conversion of the hydrated oxide into 
carbonate, as well as in its neutralization by the organic 
compounds of the soil. The carbon dioxide was eliminated 
from the calculations, because the greater part of it found 
after the decomposition of the organic matter, is a product 
of this process not originally contained in the substances
