The mechanical analysis of this soil yielded the following 
results : — 
Moisture 2-42 
Organic matter ITTO 
Lime 154 
Clay 48-39 
Sand 35-95 
100-00 
On being submitted to chemical analysis, the following results 
were obtained : — 
Moisture 2-420 
Organic matter 11-700 
Oxides of iron and alumina 11-SGO 
Carbonate of lime 1-240 
Sulphate of lime '306 
Containing sulphuric acid (-180) 
Phosphoric acid -080 
Chloride of sodium '112 
Potash (soluble in acid) -910 
Soluble silica 4-090 
Insoluble siliceous matter 67-530 
100-248 
The composition of this soil differs materially from that used 
in the preceding experiment. It is a soil which contains much less 
lime and a good deal more sand than the soil from the College 
farm. It belongs to the class of vegetable moulds, is moderately 
stiff, and bears a good and tolerably abundant herbage. 
Soil and liquid manure were mixed as before in the proportion 
of 2 of soil to 7 of liquid ; after 24 hours the clear liquid weis 
poured from the soil ; the liquid was then allowed to settle for 6 
or 8 days and then filtered. Notwithstanding every care to 
obtain a perfectly clear liquid, a little finely suspended clay passed 
through the filter. This clay is mentioned in the subjoined 
analysis as insoluble siliceous matter, and of course does not 
belong properly to the liquid. 
The analysis of the liquid left in contact with the soil was 
executed exactly in the same manner as that of the liquid in the 
preceding experiment, and the following results were obtained : — 
Composition of the inorganic matter (asK). 
Soluble silica 2-73 
Insoluble siliceotis matter 2-66 
Lime 22-51 
Magnesia 2-57 
Potash 4-04 
Chloride of potassium 4-36 
Chloride of sodium 35-03 
Phosphoric acid 1-56 
Sulphuric acid 2 44 
Carbonic acid and loss 21-50 
100-00
