ON THE CIECULATION OF UNDERaEOUND WATERS. 375 



and paved streets, and believes the larger part of this supply is derived 

 from infiltration of the waters of the rivers Irk, Medlock, and Irwell ; 

 the great natural filtering properties of the Red Sandstone are shown in 

 its rendering water, but little better than sewage, fit for commercial pur 

 poses, and capable of being used in factories, breweries, bleaching and 

 dye works. 



The following is an analysis, by Dr. Angus Smith, F.R.S., of water 

 from a deep well on the south side of Manchester, analysed in 1865 : — 



Grains per gallon 



Chloride of sodium 483 



Sulphate of soda 7-33 



Carbonate of soda 7"35 



„ lime 9-77 



„ magnesium 5-29 



34-57 

 Assuming that 5 inches of the annual rainfall is absorbed in the 7 



square miles referred to, this would give a daily average of (200,000 x 7) 



1,400,000, leaving about 4^ million gallons dady infiltrated.
