 Waterworks may be expressed thus : 



Total solids at 120 C 



Combined Chlorine 



Expressed as Sodium Chloride 

 Total hardness expressed as

In the analysis of the South-Western Mineral Works there is 

 more solid matter, as the Chlorides amount to 4-2 grains per 

 gallon, and the Lime-salts to 20 grains per gallon. Total 

 solid matter 28 grains per gallon. I have no analysis of the 

 water of the Bournemouth Waterworks, but it is not likely to 

 differ materially from the other two. Great trouble is taken to 

 soften this water by the addition of lime under a special process ; 

 the accumulated calcareous cream thus removed from the water 

 is becoming a source of anxiety as to its disposal. 



When we compare the above analyses with that of the 

 Bovington water, a considerable difference in the amount 

 and composition of the dissolved mineral matter may be noted. 

 The general result is that Chlorides, presumably of Sodium, are 

 greatly in excess of the Lime-sails. Hence the water must be 

 softer. The amount of solids obtained by evaporation is 

 returned at i6'8 grains per gallon.* There seems to be a

It is by no means easy to understand this analysis, since the amount of Chlorine 

 shown would require something like 6'5 parts of Sodium in order to form Sodium
