502 The Influence of Lime on the 
With lime-water containing '997 grs. lime in 1000, an 
absor[)tion of 7*588 grs. 
With lime-water containing 1'449 grs. lime in 1000 grs., 
an absorption of 9 '772 ,, 
To ascertain whether this rule held good throughout, an experi- 
ment was made with much more dilute lime-water. 
Experiment No. 12. 
Soil No. 16, 1000 grs. 
Lime-water (of ''997 in 1000) 14,000 grs., diluted with its own 
wciglit of distilled water, the mixture would therefore contain 
0-4985 lime in 1000 grs. 
First Analysis — 
Carbonate of Lime. 
1500 grs. gave 0*75 equal to 0*280 lime in 1000. 
Second Analj'sis — ■ 
1500 grs. „ 0*77 _ „ ''0'287 „ 
Mean of the two Experiments .. .. 0'284 ,, 
Or 7*952 in^8,000 grs. 
The lime in 28,000 grs. lime-water previous to experiment 
• at Q-4985, was .. 13-958 
Ditto after the experiment 7-952 
* fi-006 
Which is the absorption by 1000 grs. 
A further experiment was made on this subject. 
Experiment No. 13. 
500 srs. of soil. No. 16, was digested with 14,000 grs. of lime-water 
containing 1 *449 grs. in 1000 — the digestion was continued as 
before for 24 hours. 
First Analysis— 
Carljonate of Lime. 
1500 grs gave 2-54 equal to 0*904 lime in 1000 • 
Second Analysis — 
1500 grs gave 2-55 .. .. .. „ 0*905 „ 
Mean of the two Experiments .. 0*9045 ,, 
Or 12*C6;3 in 14,000 grs. 
The 14,000 grs. of lime-water employed contained .. 20*286 lime 
Tlie li(;iiid afterwards contained 12 -003 ,, 
Absorbed by 500 grs. of soil 7 623 ,, 
Or an absorpiion by 1000 grs. of soil of 15 246 „ 
Here, then, we have the quantity of lime absorbed by the 
same soil in one case, 6*000 in 1000,' and in another as much as 
15*-i4:G by the same quantity ; and, to all appearance, this dis- 
similarity is entirely due to the different relations in the quantity 
of lime and of soil, the soil appearing to unite witli the lime in 
greater quantity the more that is presented to it. Without at
