Frankland. The remarkable features of this analysis are the quantities of iodine and bromine. Professor Frankland, for the Geological Survey, found, of iodine, 6.1 grains in 10 gallons of the water; bromine, 44 grains in ditto. As compared with the water of Cheltenham, of Leamington, and of the famed German Spa at Kreuznach, we have the original analysis of Mr. West, of Leeds, giving:— In 10 galls. Iodine. Bromine. Cheltenham one third grain one and two-thirds grains Leamington one grain four grains Kreuznach one and one-quarter grain twenty-five grains Woodhall six and one-sixth grains forty-four grains The Woodhall water, therefore, has five times the amount of iodine, and nearly twice the amount of bromine, of the strongest known Continental water. {99a} I mentioned, in Chapter I., that the Dead Sea, in Palestine, was stronger in bromine than Woodhall. According to M. Marchand’s analysis, it contains bromide of magnesium 74 times the amount at Kreuznach, or about 30 times the strength of Woodhall; but the other great ingredient of the Woodhall water, iodine, is absent from the Dead Sea. {99b} In iodine the only known water surpassing Woodhall Spa is the spring of Challes in Savoy, {99c} which contains 1.045 parts per 100,000 of water. I may add that at Old Woodhall, about four miles distant from “The Spa,” at a depth of 33 feet, in sinking a well, some 20 years ago, salt water was tapped, resembling in taste that of the Woodhall Spa well, but it gradually became less salt, and finally was replaced by a supply of fresh water. {99d}
