Here we notice that in almost every instance all the 
mineral ingredients of the plant were extracted from 
these soils by water. Only magnesia and chlorine are in 
any case missing. We are not informed, unfortunately, 
what amount of soluble matters was obtained in these 
experiments. 
We next adduce a number of statements of the pro- 
portion of matters which water is capable of extracting 
from earth, statements derived from the analyses of soils 
of widely differing character and origin, 
I. Very rich soil (excellent for clover) from St. Martin’s, 
Upper Austria, treated with six times its quantity of cold 
water (Jarriges). ; 
II. Excellent beet soil (but clover sick) from Schlan- 
staedt, Silesia, treated with 5 times its quantity of cold 
water (Jarriges). ; 
III. Fair wheat soil, Seitendorf, Silesia, treated with 5 
times its weight of cold water (Peters). 
IV. Inferior wheat soil from Lampersdorf, Silesia— 
5-fold quantity of water (Peters). 
V. Good wheat soil, Warwickshire, Scotland—10-fold 
quantity of hot water (Anderson). 
VI. Garden soil, Cologne—3-fold amount of cold water 
(Grouven).
