' B.' contains a larger proportion of mineral salts than is usual in even 

 the hardest water used for domestic supply, but there is nothing injurious 

 in these salts except that they waste soap and prevent the water from 

 cleansing the skin even with a great quantity of soap, as well as from 

 cooking such things as tea without great waste. 



There is no organic matter and no products derived from any previous 

 sewage contamination ; it is free from common salt. 



' W.' is not quite so free from organic matter, but the quantity of 

 organic matter derived from it is very small. 



The hardening salts and the other mineral salts are within ordinary 

 limits. 



As a general rule the deep bore waters are safer than upper waters.
