 Waters. Chem. News, vol. xxxii. p. 207. 

 , Analyses of the water of the Nile show that in June, when the river 

 is beginning to rise, it contains only 1*8 grain of chlorine per gallon ; 

 but when it attains its greatest size, the chlorine sinks to 0-3 or 0*4 grain 

 per gall., and continues low until the end of the year. This enormous 

 diminuti6n in the chlorides is attributed to the fact that the Nile is 

 swollen with storm-water, which sweeps over the surface of the country 

 without penetrating far below the surface, and thus carries down little 

 or no salt. The hardness of the water remains constant. The water 

 of the Nile contains as much organic matter as the Thames at Hampton 

 Court, but has only about half the hardness of London Thames water.

 The water of the Thames at Hampton Court contained, in Nov. 

 1875, only 0*88 grain of chlorine per gall., the usual proportion being 

 1-2 grain. P. W. R.

Sellalield, near Whitehaven. Chem. Neivs, vol. xxxii. p. 11. 

 Complete analysis of sample collected June 2, 1875. 



Note on the Chalybeate Water at Sellafield, near Whitehaven. 



Chem. News, vol. xxxii. p. 309. 

 Traces the origin of the spring to drainage through a clayey soil 

 containing ferrous and manganous oxides, whence the cause of its 

 chalybeate character. Analysis of the clayey earth is given.
