or streets, which has caused the underground water to no longer flow from 

 the sandstone towards the sea, but to allow a current of tidal water to set in 

 towards the land, which gradually increasing in volume, the water in these 

 wells becomes yearly more and more charged with salts. 



A well at (1) Earl Street, 350 yards from the Mersey, was perceptibly 

 affected by the tide, the top water sinking to low-water level at low tide, 

 the bottom of this well being 32 feet below high water. 



In a well at (2) Kainford Square, 500 yards from the river, the bottom of 

 which is 76 feet below high-water mark, the supply is abundant ; and Mr. E. 

 Davis, F.C.S., found bj' analysis that it contained 



grains. 



Mineral matter per gallon 231-00 



Organic matter ,, 1-75 



232-75 



The mineral matter consisting of: 



o 



Chloride of calcium. Sulphate of lime. 



,, magnesium. „ magnesium. 



„ potassium. Carbonate of lime. 



„ sodium. „ magnesia. 



Oxide of iron. Nitrate of ammonia, trace. 



The large quantities of salts in this well render it unfit for generating 

 steam, for which it was formerly used. 



In the water from a well (3) at Johnson Street, 850 yards from the Mersey, 

 Mr. Phillips, of London, found the following salts per gallon : — 



grains. 



Sulphate of lime 8-80 



Carbonate of lime 24-33 



Chloride of lime 5-05 



„ magnesium 20-80 



„ sodium 55-79 



114-77 



The analysis was made in 1850, up to which time the water was suitable for 

 brewing, but afterwards became so brackish that its use had to be discontinued. 

 A well in (4) Wellington Street, about 1200 yards from the river, was 

 sunk in the Keuper Sandstone to a depth of 71 feet below high water. An 

 analysis of the water from a peighbouring well, made in 1865, gave 117-70 

 grains of solid matter per gallon, consisting of : — 



grains. 



Sulphate of lime 29-50 



Chloride of lime 4-00 



,, magnesium 33-60 



„ sodium 47-60 



Carbonate of lime 2-00 



Iron, alumina, &c 1-00

 (Analysis made by Messrs. Huson and Audle for Mr. "Westworth.) 



An analysis of the Corporation well at Eootle, about 1800 yards from the 

 river, made in 1850 by Mr. Phillips, gave 24 grains of solid matter per
