The remarkable changes which took place in the composition 
of the original liquid when left in contact with the Cirencester 
soil will appear by a study of the subjoined tabular statement, in 
which the composition of the liquid manure before and after 
contact with the soil is given, and which also states the gain or 
loss in the several constituents found in the filtered liquid. 
Composition of Liquid Manure before and after Filtration through soil from
