sulfur is easily explained if it be accepted that the dip is a mixture 

 of two or more sulfides decomposing at different rates. 



Assuming, for the sake of comparison, as has been stated before, 

 that the dip is a solution of a mixture of monosulfide, pentasul- 

 fide, and thiosulfate, then on the first day 2CaS + TCaSs + CaS-iOa 

 would correspond to the different percentages, while CaS + QOaSs 

 + SCaSsOg would represent the mixture for the percentage given on 

 the sixteenth day.
