ACTION OF LIME AS A MANURE. 
12 
and 10.43% calcium carbonate. The following mixtures were 
made : 7 8 
A. DRY LAND SOIL. 
I. 290.55 grms. air-dry soil = 200 grms. dry matter, 
10.995 g rms air-dry soy beans = io grms. dry matter, and 
50 c. c. water. 
II. The same mixture with the addition of 14.375 g rms - 
slaked lime = io grms. CaO. 
B. PADDY SOIL. 
I. 317.965 grms. air-dry soil = 20o grms. dr} 7 matter, 
10.995 grms. air-dry soy beans = io grms dry matter, and 
300 00 water. 
II. The same mixture with the addition of 14.375 grms. 
slaked lime = io grms. CaO. 
These mixtures were put into spacious wide-mouthed glass 
bottles and closed air-tight with twice perforated rubber plugs 
furnished with glass pipes, through which every two days air 
free from carbon dioxide was guided over the soil but which 
were otherwise kept closed. From time to time samples of 
the mixture were taken out from the bottles and submitted 
without delay to determinations of dry matter, organic matter 
and combined water, carbon dioxide, and mineral matter free 
from carbon dioxide. 2 
The results of these investigations are compiled in the 
following table :—• 
7 As to the slaked lime we should mention that for every trial so much was 
weighed out as corresponded exactly to 10 grms. of calcium oxide (CaO). 
8 The two kinds of original soil were free from carbonates.
