510 Tlie Influence of Lime on the 
Soil No. 5, gault clay, from the surface. 
Experiment Ko. 33. 
Ammonia in soil No. 5 in its natural state. 
First Analysis — 
Platinum Salt. Ammonia in 1000. 
1000 grs. distilled gave 1-44 equal to 0-1097 
Second Analysis — 
1000 grs. „ 1-92 „ 0-1461 
Mean of the two Analyses 0*1274 
Experiment No. 34. 
Soil No. 5, exposed to ammoniacal vapour after liming. 
First Analysis — 
Plalinum Salt. Ammonia in 1000. 
500 grs. distilled gave 21-82 equal to 3-3-27 
Second Analysis — 
300 grs. ,, 12-61 „ 3-204 
Mean of the two results 3-265 
Experiment No. 35. 
Soil No. 5, exposed to ammoniacal vapour without liming. 
First Analysis — 
Platinum Salt. Anmionia in 1000. 
300 grs. distilled gave 10-14 equal to 2-573 
Second Analysis — 
300 grs. „ 10-46 ,, 2-658 
Mean of the two results 2-615 
The determinations of ammonia in the case of the natural soil 
do not agree so closely as might be vi^ished, and the quantity of 
ammonia in the soil after liming was not determined ; there is, 
however, in the present instance some indication of an increased 
absorption of ammonia due to the liming, for we find — 
In the soil limed and exposed to ammonia 3-265 
In the soil exposed to ammonia without liming 2-615 
Still the difference is not great, and it could hardly be expected 
to have any practical effect, since the soil is capable of absorbing 
so much ammonia, even without the aid of lime.
