In Table I. the alkalies are exhibited as if they were all in the state 

 of hydrochlorates of potash and soda, or more correctly chlorides of 

 potassium and sodium, chloride of sodium or common salt being the 

 best type of such compounds, and the one most familiar to us, and 

 practically most important. The earths are exhibited as if they were 

 all in the state of carbonates of lime and magnesia, these compounds 

 being also the most familiar ones. By this arrangement, the relative 

 proportion of these constituents at different seasons can be easily 

 compared. I am not aware that this plan has been used before, but 

 it seems to me a good one, particularly when combined with the 

 results given in Table II. 



* Silica mixed with more or less clay.
