We tind united in table 1 the results of tlie ditfereiit analyses ; 

 all the small bottles have been shaken in a thermostat during from 

 three to live weeks. Although the .l.s„'^>3 and the compound Z) formed 

 both an extremely fine powder, the eye could easily distinguish them 

 by their difïerent behaviour on sinking. 



TABLE 1. 



Composition in percentages by weight at 30° 



The solubility of KCl in pure water (n°. J4 of table i) has not 

 been determined but has been taken from the tables of Landolt- 



BoRNSTEIN. 



As table I shows, besides the compositions of several solutions, 

 also the rests belonging to them, are determined ; the numbers placed 

 between parentheses in n°. 13 indicate however the composition of 

 the complex. In order to examine if in the determinations errors might 

 have occurred by analysis or anything else, several complexes were
