KENTUCKY SPRINGS. 173 



sulphur, iron, and carbon, undergoing certain changes of 

 position from the original composition of the water." The 

 water also contains nitrogen gas, with carbonic acid, and 

 sulphuretted hydrogen. For saline contents, see analysis 

 just quoted from the third volume of the Geological Survey 

 of Kentucky. 



The medicinal properties are those of salt sulphur waters 

 generally, and used in all chronic derangements to which sul- 

 phur waters are prescribed, both internally and externally. 

 (See Owen.) This water is distributed extensively by barrel- 

 ing and bottling. Being, according to Dr. Drake, in a region 

 of perpetual malaria, the place is thus doomed for certain 

 seasons of the year. 



Of ESTILL SPRINGS, in Estill County, Kentucky, see also 

 Report, page 245. Two springs, called "White and Eed 

 Sulphur," give, in the first, carbonic acid and sulphuretted 

 hydrogen gases, carbonates of soda, lime, magnesia, and 

 iron, sulphates of lime, magnesia, and soda, chloride of so- 

 dium, and hydrosulphate of soda; specific gravity, 1-001; 

 saline contents, 0*09 per cent. 



The " RED SULPHUR" contains carbonic and sulphuretted 

 hydrogen gases, carbonates of lime, magnesia, soda, and iron, 

 sulphates of soda, lime, and magnesia, chlorides of sodium, 

 calcium, and magnesium, and hydrosulphate of soda. The 

 composition is similar to White, only differing in proportion 

 of elements and specific gravity, 1*0002; saline contents 

 0'04 per cent. (Peter.) 



The Kentucky springs have each special advocates, who 

 speak emphatically of the power of their waters. Some of 

 these authorities are so high that the medicinal properties 

 of the waters as represented, stand, with certain qualifications 

 which apply to all springs, accredited by the profession at 

 large ; as do those of the other States, which have been 

 made the subject of special examination. When the Geo- 

 logical Survey, now progressing under Professor Owen, shall 

 have been finished, no doubt the mineral springs of Kentucky 

 will appear with the last chemical details and geological
