distilled water. The percentage of soluble matter was 

 only *477, and this consisted mainly of magnesium sulphate 

 a little chlorine, lime and alumina were also present. The 

 magnesium sulphate was probably due to the action of the 

 sulphuric acid formed by the oxidation of the iron sulphide 

 present.
