Analysis of ashes of plants from the rivers Ohe and her. DR. WITTSTEIN. 



* The great difference in the composition of the ashes of one and the same 

 plant arises, according to Dr. Niigeli, less perhaps from the different amount 

 of these matters in the water than from difference of age in the plan is, and 

 probably more still from other plants which nestle in the moss.
