An examination of Table IV below suggests the following 
summarized statements: (1) The amount of sulphide sulphur 
in Solution increases generally when the amount of lime. used 
increases. (2) The use of increased amounts of lime appears 
to result generally in the production of smaller amounts of 
thiosulphate sulphur but somewhat larger amounts of sulphite 
sulphur, as already pointed out (p. 364). (3) The amount of 
lime in solution is notably increased by use of larger amounts 
of lime. (4) The amount of sediment is usually somewhat 
greater when larger amounts of lime are used. (5) The amount 
of free sulphur in sediment is notably less when larger amounts 
of lime are used. (6) The amount of lime in sediment is 
usually greater when increased amounts of lime are used.

The facts can be made still more readily comparable by con- 
sidering in more detail two particular points: (1) The relative 
distribution of sulphur as sulphide and thiosulphate and as 
combined sulphur (sulphite and sulphate) in sediment; (2) 
the relative amounts of calcium polysulphides (CaS, and 
CaS.) present in solution. These points we will now 
consider.
