a Estimated by calculation from the results for the various forms of sulphur— not by direct deter- 
mination. 
The figures for hydrogen sulphid sulphur in themselves possess 
little significance from a quantitative point of view, the exact amount 
present depending upon variable factors. But the figures can be 
utilized to obtain a nearer approximation to the value of x in CaS x 
than given in the table for the value in M 2 S X . If this form of sul- 
phur is present only as free hydrogen sulphid, then the value for x in 
CaS x of Preparation B becomes 4.92, while if all hydrogen sulphid 
is present as calcium hydrosulphid the value of x is raised to exactly 
5.00. All the other preparations under Experiment 1 naturally give 
lower values. 
The next undertaking was to determine the effect of varying the 
period of boiling. 
EFFECT OF VARYING PERIOD OF BOILING. 
EXPERIMENT 4. 
Using the formula 45 : 100 : 514, which had shown the best utilization of both 
lime and sulphur in Experiment 3, concentrates were prepared, diluted, and 
analyzed exactly as described under Experiment 3, except in the period of 
boiling. The results are given in Table 2. With Preparations F and G is also 
to be included Preparation B, under Experiment 3, as the first member of the 
series. 
Under the conditions of Experiment 4, boiling for 0.5 hour and for 
one hour produced practically identical results; that is, boiling for 
the shorter period appeared to produce as complete and perfect a 
reaction as possible, while boiling for a further half hour seemed to 
effect no material injury. The higher value for x in M 2 S X shown 
after 0.5 hour boiling is chiefly due to the less amount of hydrogen 
sulphid which happened to be present. Ass inning free H 2 S the value 
of x in CaS x is 4.94, and assuming Ca(SH) 2 it is 4.98.
