interpreted wrongly for it is a fact that addition of S, lowers the 
transition point. The highest point given by Kruyt for the metastable 
equilibrium Sr Sar is 96°. Above this, Sp when passing into Sy,

ought to begin to melt. This statement is rather remarkable when 
we read that Kruyt in the Chem. Weekbl. 648, (1911) actually states 
that all values for the 7—, on change of S,-content, lie lower than 
95°.6. I should like to ask, how that temperature has been found ? 
Also, the high values (97°.6 and 97°), determined by GERNEZ and 
Rercuer, find no room in Krvyt’s Figure. 
Hence, it is faulty without any doubt to let CG proceed to higher 
temperatures; this line falls. If, however, we draw CG sinking we 
obtain a Figure which is identical with a figure previously given 
by Prof. Smits (Proc. 1911, 264) and represented here by Fig. 4. 
This identity becomes perfect if we leave out the dissociation region 
drawn therein (which as stated in a note ought to be discarded as 
not a single experimental fact points to its existence). In this way we 
obtain Fig. 5. What Kruyt (fig. 3) calls CG is in fig. 4 and 5 op ete. 
The deduction of the transition point of the sulphur with the aid 
of the equilibria lines of the solid substance is therefore not due to 
Krurr.
