Rises in Worcestershire, and it contains lime with a small proportion of magnesia, suspended chiefly by carbonic acid gas. A very small quantity of sea salt is occasionally found in it. The proportion of fluid is very large, and this is one of the purest of our cold mineral waters. It is applied in inflammations of the eyes, and drunk in all complaints of the kidneys and bladder, scrofula and cutaneous diseases.
Dr. Wilson, in a late elaborate work on this water, seems to think that its solid contents, though in a small proportion, may be useful, especially as they are of the kind used in the diseases for which the water is celebrated. He found in a gallon of Holywell water above five grains of carbonate of soda, and nearly three of the sulphat of soda. It contained also about a grain and half of common salt, nearly a grain of carbonate of magnesia, and about the same quantity of carbonate of lime. The carbonate of iron scarcely exceeded half a grain. The ingredients of St. Ann's Well were the same, but in a much less proportion. He found the waters laxative; but, at first, they sometimes produced nausea, and occasionally feverish heat.
