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.
