T. Shaw, M.R.C.S., in 1830 stated:— ' The water is, perhaps, for 
its purity, tenuity and coldness, the best qualified ... of any 
water in this part of the country. It has been frequently analysed, 
but the decomposition always proved that it contains no medicinal 
quality ... it is purity and softness only, which makes it more 
efficacious . . . than any other water known. "f 
There is a reference to the water in the " Spas of England."!
