CHALYBEATE SPKINGS. 513 
Corribrash, fyc. 
Boad, north-east of Frome (saline chalybeate). 
Chippenham (saline chalybeate). 
North Leigh, north-east of Witney.

Sempringham, east-south-east of Folkingham. 
Saline Springs. 
Saline waters have been proved in a number of localities in the 
Oolitic strata, as follows : 
Inferior Oolite. 
East Chinnock, south-west of Yeovil. Salt-house, between East and 
Middle Chinnock, where common salt was formerly obtained in 
quantity. 
Chadlington, near Chipping Norton. 
Woodhall Spa, near Horncastle. (See p. 515.) 
Great Oolite Series. 
Melksham Spa, near Bower House, south-east of Melksham. (See 
p. 514.) 
Trowbridge (well-boring). (See p. 514.) 
Swindon (well-sinking). (See p. 515.) 
Braceborough Spa, south of Bourn, and north of Braceborough 
Station (contains carbonate and sulphate of lime, sulphate of soda, 
and chloride of sodium). 
Aunsby, south-west of Sleaford (160 grains of salts per gallon). 
Heckington (well-boring), south-west of Sleaford (127 grains per 
gallon, chiefly chloride of sodium). ' 
Other mineral springs have been recorded from the Inferior Oolite and 
Great Oolite Series at the following localities : 
Hyde, north of Temple Guiting, Gloucestershire ; Kingsthorpe ; Stan- 
wick ; Higham Ferrers ; near Oundle (Drumming Well) ; Warmington, 
north-east of Oundle (Chadwell) ; Weedon Lois, west of Towcester (St. 
Loy's Mineral Spring), in Northamptonshire; and Spital-in-the-Street 
(Spa), Lincolnshire. 
At Blatherwycke, north-west of Oundle, a spring containing sulphur- 
etted hydrogen was discovered in sinking a well through the North- 
ampton Sands, &c. to the Upper Lias Clays. 
Carbonic acid gas is given off from the waters at Woodhall Spa : and 
the same gas together with Nitrogen, Oxygen, and Chlorine, are said to 
be evolved from the waters at Braceborough Spa.* 
The mineral water .at St. Clement's, Oxford, was found in sinking an 
Artesian well in 1832. The well was carried through 265 feet of Oxford 
Clay and to a further depth 155 feet in rock (Lower Oolites, &c.). 
Buckland remarked that when the bore-hole was first made, the water 
rose 3 or 4 feet above the surface in a considerable volume, f It was 
found on subsequent analysis to yield (per gallon) 748 grains of chloride 
of sodium, 357 grains of sulphate of soda, 136 of sulphate of lime, together 
with small quantities of chloride of magnesium and carbonate of lime, 
bringing the total to 1,277 grains per gallon. This water rose when the 
clay was pa?sed through, from a depth of 280 feet ; afterwards when the 
boring Tvas carried lower the water was not so strongly charged with 
sulphuric salts. + This last fact is important.
