ACTION OF LIME AS A MANURE. 
17 
The percentage amount of nitrogen applied in the manure 
was accordingly in the dry land soil 0.162%, in the paddy soil 
0.150%. 
After filling, the jars were digged into the respective fields 
up to about 5 centimetres from the upper edge, and the paddy 
soil was irrigated with distilled water, the level of which was 
kept throughout the whole time of the experiment about 2 
centimetres above the surface of the soil. The jars on the 
dry land were merely kept at the same degree of moisture as 
the surrounding field. To prevent dust and rain from en¬ 
tering the vessels, large glass plates were suspended over 
them. After standing for some time we determined the quanti¬ 
ties of nitric acid, according to Schulze-Tiemann’s method, 
and of ammonia, according to the method elaborated by A. 
Baumann, 9 the only modification being that the ammonia was 
thrown down with platinic chloride from which we weighed 
the platinum after ignition. The results calculated per jar, 
were the following :
