The chlorides and other salts in this well undoubtedly come from sewage 

 matter in the ground in the neighbourhood. In 1868, when it was not 

 pumped but contained condensation water from the engines, it yielded total 

 solids 14 and nitrates -142.

Note. — The nitrates seem to havo been overlooked in this analysis. 



In 1868, after the well was disused, the water yielded — total solids 

 65-1, nitrates 6-43, hardness 20°. It must have contaiued nitrates in 1850. 

 The nitrates and chlorides undoubtedly come from sewage matter in the 

 neighbouring soil. The carbonates of magnesia and lime could not have 

 come from sea-water ; there is no trace whatever of sea- water in the well.

The salts in this water come either from the sea or from the marine beds 

 in which the well is sunk ; a small quantity of the lime salts also comes 

 from other sources. Although I do not believe that any of the corporation 

 wells contain any serious proportion of sea-water, there are private wells on 

 both sides of the Mersey which do contain appreciable quantities of sea- 

 water.
