5286 s The Purification of Water by Continuous Fractional Distillation. By William 

 Robert Bousfield, M.A., K.C. Patent No. 25699/01 



The above apparatus is stated to produce by a process of continuous fractional distillation, a water equal 

 la purity to that prepared by Stas for his atomic weight determinations. 



The still can be run continuously day and night, producing a total of some ten litres a day, which may be 

 roughly divided into three qualities, and it has the advantage over Stas' method that the purification is effected 

 in one operation instead of three. The best quality water has a conductivity of about X = ixio ,a value which 

 may be taken as typical of a thoroughly good sample of conductivity water.
