508 The Influence of Lime on the 
In point ol fact, therefore, this soil absorbs more ammonia 
from an atmosphere containing^ it, without the previous action of 
lime, than it does with the intervention of this agent. 
We pass on to the soil No. 17. 
Experiment No. 25. 
Soil No. 17 in its natural state. 
First Analysis — 
['latinuin Salt. Aniiuoiiia in 1000. 
1000 grs. distilled, gave 1-11 .. equal to 0 080 
Second Analysis — - 
1000 grs. distilled, gave 1-24 .. ,, 0-091 
Mean of the two results 0 085 
Experiment No. 26. 
Soil No. 17 after liming. 
First Analysis — 
Platinum Salt. Ammonia in 1000. 
1000 grs. distilled, gave 0-54 .. equal to 0-0412 
Second Analysis — 
1000 grs. distilled, gave 0-52.. ,, 0-0396 
Mean of the two Analyses 0-0404 
Experiment No. 27. 
Soil No. 17, after liming and exposure to ammonia. 
First Analysis — 
Platinum Salt. Ammonia in luOO. 
500 grs. distilled gave 21-42 equal to 3-2956 
Second Analysis — 
500 grs. ,, 21-44 „ 3-2987 
Mean of the two results 3-2972 
Experiment No. 28. 
Soil No. 17, exposed to ammonia without previous liming. 
First Analysis — 
I'latinum Salt. Ammonia in 1000. 
250 grs. distilled gave 10-68 equal to 3-2864 
Second Analysis — 
250 grs. „ 10-68 „ 3-2864 
Mean of the two results 3*2864 
The soil No. 17, therefore, gave the following results: — 
Ammonia. 
1000 grs. soil in its natural state contains 0-085 
Ditto, after litning 0-0404 
Ditto, after liming and exposure to ammonia 3-2972 
Ditto, after exposure to ammonia without previous liming .. 3-2864 
In this instance again the liming has not in any sensible 
degree increased the power of the soil to absorb atmospheric 
ammonia.
