Although it may be classed as a mild chalybeate, I have frequently seen great benefit derived from its internal use (partly, no doubt, owing to the presence of sulphate of lime), especially in children of an undoubtedly strumous habit, where glandular swellings presented themselves in the neck, and the mesenteric glands were enlarged. In such cases, when taken regularly for some weeks (half a tumbler thrice daily after meals), the appetite returns, the digestive functions are improved, the glandular swellings subside, and the whole system becomes reinvigorated, so as to restore bloom to the cheek, brilliancy to the eyes, vigour to the limbs, and the natural buoyancy of spirit to childhood. According to Dr. L. Playfair’s analysis in 1852, one gallon of the water was found to contain the following solid constituents:— Grains. Pro-carbonate of Iron 1.044 Silica 1.160 Sulphate of Lime 2.483 Alumina trace Sulphate of Magnesia 0.431 Carbonate of Magnesia 0.303 Sulphate of Potash 0.147 Chloride of Sodium 1.054 Chloride of Potassium 0.450 7.072 The thermal water, as before stated, arises from various fissures in the limestone rock, upon which formation the greater part of the town of Buxton is built. The flow is uniform (during the heat and drought of summer, and the cold and frost of winter) in volume, about 140 gallons per minute, in temperature 82 deg. Fahrenheit, and in solid constituents. According to the latest analysis, made by Dr. Thresh in 1881, the following results were obtained. The mud which had settled around the mouths of the springs and floors of the tanks into which the water is conveyed consisted of— Grains. Oxide of Manganese 80.32 Sulphate of Barium, Sand, &c. 1.08 Lead Oxide 0.15 Copper Oxide 0.07 Molybdic Acid 0.02 Iron and Aluminium Oxide 1.36 Cobalt Oxide 0.30 Zinc Oxide 0.46 Barium Oxide 0.79 Calcium 5.31 Strontium trace Magnesium 3.18 Carbon Dioxide 3.23 Phosphoric Acid 0.01 Water 3.93 100.21 The following is the result of his analysis of the water:—
