We have liere a soil which hardly contains any lime, and such 
minute traces of phosphoric acid, that this constituent could not 
be determined quantitatively. 
The sand obtained by washing had a deep red colour, and con- 
tained a good deal of oxide of iron. 
. Tlie composition of this soil fully explains the extremely infertile 
character of the land, and its avidity to swallow up manure with- 
out exhibiting any corresponding elfect on the produce. 
A portion of the soil, sufficient for the purpose of ascertaining 
the changes which liquid manure undergoes in contact with the 
soil, was mixed with this liquid, and the experiment carried out 
in all particulars precisely in the same manner as in the two 
preceding cases. 
The following results were obtained : —
