248 S. W. Johnson on the Soil-analyses of the 
is explained by its very small proportion of lime, and rather 
ll amount of sulphuric and phosphoric acids. The addition 
of plaster of Paris or some of the calcareous marls would prob- 
ably restore it to the capability of supporting a clover crop.” 
The percentages of the ingredients which Dr. Peter considers 
deficient, are as follows: 
Carbonate of lime, - : - 0:072 =lime 0:040 
Sulphuric acid, - - - 0°055 : 
Phosphoric acid, ee - 0:070 
Small as are these quantities, the smallest of them, viz., that 
of lime, yet amounts to s. per acre, which is enough to 
reproducing his figures, which tnay be found in the Trans. of the

obtained from the analyses of two portions of soil from different 
parts of any field.” 
n the present year, Stoeckhardt (Chemischer Ackersmann, 
No. 2, 1861, p. 85), has published an account of several “clover- 
sick” soils from Schlanstaedt, which reveal to analysis a greater 
content of every nutritive mineral ingredient both soluble in water 
and in acids, than exists in another soil from Frankenstein which 
produces clover and wheat as well. What proves beyond @ 
doubt that the inability of these soils to yield clover epends 
upon something besides their chemical constitution, is the 
that lucerne and esparsette still flourish upon them admirably, 
and further, clover itself, if sown with one of these last men 
tioned crops, succeeds very well. : |
