The author has some doubts whether the whole of the iron exists as 

 bicarbonate ; certainly by far the greatest proportion is in that state, 

 because upon standing an ochre is deposited and the water has but a 

 very slight action on iron tests. Some experimenters have imagined 

 that a part was dissolved as sulphuret, and others have found the iron 

 as metal upon evaporation ; but Mr. Herapath found no direct evidence 

 of the first ; and as to the second he observes that every experimenter 

 who found metallic iron had evaporated in a brass or other metallic 

 boiler, which w^ould easily account for its presence ; but it is not un- 

 likely that a small portion is held in solution otherwise than as bicar- 

 bonate. 



The other water was found in Kingsmead-street. A well 59 feet 

 deep and 40feet boring had been upon the premises for some time, which 

 contained water of the temperature of 76°, and from the heat of its sides 

 it was evidently in the neighbourhood of hot water. As this spring fur- 

 nished but 35 hhds. a day, and more was wanted, a boring hole was 

 made which passed through the following strata : 



35 feet of blue lias. 



50 white lias. 



11 white clay. 



11 sulphur clay. 



1 red soil.

 When at this depth no water was found ; but one morning upon the 

 workmen arriving the well was discovered to be full of hot water to
