already known'). From their determinations, SCHREINEMAKERS and 
Fieke thought they might conclude that the other oxy-salt should 
have the composition 
CaCl, .4 CaO .14 H,O 
As the region of existence of this salt at 25° was, however, still 
but very small, a slight error in the determination of this composi- 
tion was still possible. 
Temperature 50°. At this temperature occur, besides CaCl, . 2 H,O 
and Ca(OH),, also the two oxychlorides: _ 
Ca OH: ‚HO and Ca OH .2H,O

first one already exists at 10° and 25°, the last one had not been 
described, as yet. 
The system: CaBr,—CaO—H, 0. 
In this system, only the isotherm of 25° has been determined ;

bromides :

The latter salt was not known up to the present; the first one has 
been described previously. °) .
