Vol. 50.] BORINGS AT CULFORD, WINKFIELD, WARE, AND CHESHUNT. 501 



Analysis of a sample of water received from Messrs. Le Grand and 

 Sutcliff, 27th May 1893, from New Lodge, Windsor Forest, 

 at the depth of 1243 feet, by Dr. B. Dyer. 



Grains. 



Total dissolved matter 61 "74 



Loss on incineration of residue *84 



Chlorine in chlorides (equal to chloride of sodium 43*37). 26 - 32 



Tree (actual or saline) ammonia "045 



Albuminoid (organic) ammonia *003 



Oxygen, absorbed by oxidizable organic matter, etc., from 

 a solution of permanganate of potash at a temperature 



of 80° Fahr In 15 minutes. -003 



„ „ In 4 hours . . '011 



Phosphoric acid traces 



No nitrogen in nitrates. 

 Hardness before boiling 3°, after boiling 0°. 



Appearance in two-feet tube turbid. Microscopic examination 

 satisfactory. 



The dissolved matter consisted of the following (in grains) : — 



Carbonate of lime 2-24 ^ 



Carbonate of magnesia "73 



Carbonate of soda 4*99 



Sulphate of soda 9*17 }■ 61*74 



Chloride of sodium 43-37 



Oxide of iron and alumina *28 



Silica, traces of organic matter, etc. '96 J 



" So far as regards organic matter this water is remarkably pure, 

 as would be expected from the depth. The most remarkable 

 feature about it is the presence of a large quantity of common salt. 

 This of course is not prejudicial to health, though persons of delicate 

 palate might detect a faint trace of salt. The hardness is only 

 3 degrees, so that for laundry purposes the water would be 

 economical. It would also be excellent for boiler purposes, in the 

 sense that it would not form a crust; though a steam-boiler, of 

 course, would want occasional blowing-out — owing to the con- 

 centration of salt." 



IV. The Ware Boring. 



History of the Work. 



The site of this boring is on the alluvial flat of the Elver Lea, 

 between the Hertford Branch Railway and the stream from 

 Chadwell Spring, and | mile N.E. of that spring. It is marked 

 by the word " Well " on the Ordnance map (Hertfordshire. 

 Sheet 29). The level of the surface is about 110 feet above 

 Ordnance datum. The work was undertaken by the New River 

 Company (who have given the name Broadmead to this Pumping 

 Station), partly for the purpose of obtaining a larger water-supply 

 from the Chalk, and partly with the object of ascertaining whether 

 water-bearing Lower Greensand could be found below the Gault.
