gallon, including 9 of carbonate of lime, together with small quantities of 
salts of magnesia, sodium, &c.* 
There is a village of Holy well, north of Stamford ; a Holy "Well, at 
Fulbeck, between Grantham and Lincoln, a strong spring that issues 
from the base of the Inferior Oolite ; and at Ancaster there is the Lady 
Well, that comes from the Inferior Oolite. 
At Doulting, east of Shepton Mallet, there is a spring known as St. 
Aldhelm's Well, which issues from the Inferior Oolite. 
Petrifying Springs. 
Springs of a " Petrifying " nature, depositing carbonate of lime 
on objects placed within their influence, and sometimes, as at 
Dursley forming important accumulations of tufa, have been met 
with in a number of localities where springs issue from the lime- 
stones of the Great and Inferior Oolite Series. 
Such springs occur at the junction of the Inferior Oolite Series and 
Lias clays at Chalford near Stroud ; at Dursley (Broadwell) ; Chedworth ; 
North Aston and Somerton, south-east of Deddington ; at Old (or Wold) 
near Maidwell, south-west of Bothwell ; at Brixworth, and Pytchley. 
Issuing from the Great Oolite Series are the Magdalen Mead well north 
of Tetbury, and springs at Northleach, and at Eaunds, north-east of 
Higham Ferrers. The waters that flow over the weir from Blenheim 
Lake, deposit tufaceous coatings on twigs, leaves and other objects. 
Chalybeate Springs. 
Chalybeate Springs frequently issue from the ferruginous 
strata; some of them are locally known as "Red Wells," anil 
others formerly had some reputation as " Spas."
