We observe that lime, potash, and sulphuric acid, are 
much less abundant than in the soil from the Zuider Zee. 
The quantity of phosphoric acid is about the same. The 
amount of sulphuric acid is but one-twentieth that in the 
Holland soil, and is accordingly enough for 15 good bar- 
ley crops. 
Lastly may be instanced the author’s analysis of a soil 
from the Upper Palatinate, which was characterized by 
Dr. Sendtner, who collected it, as “the most sterile soil in 
Bavaria.”
