and iiiixriires containing all foni- ions are represented hy a point 

 witiiin the quadrangle. If now, in the point indicating the proportion 

 of salts in the solution, we erect a per|)endicnlar line of the length 

 m, the composition of this solution will then he fully determined 

 by the terminal point of the perpendicular line. 



The equilibria at 25°. 



The solutions saturated with one or more of the solid salts are 

 indicated in table I. 



Fig. J is the horizontal projection of the spacial tigure.

In addition to the lines indicating the equilibrium with two solid 

 salts are also projected therein the hiohydores, the lines that unite 

 saturated solutions with equal water contents.
