MISSISSIPPI SPRINGS. 



IN the Geological Report of Mississippi for 185T, by L. 

 Harper, we are presented with some facts with regard to 

 the mineral springs of that State. First are the springs of 

 the carboniferous formations. These are sulphur and chaly- 

 beate, or waters containing sulphate of iron and sulphuretted 

 hydrogen, and depositing yellow hydrated peroxide of iron. 

 Other springs contain iron, lime, magnesia, alumina, and 

 carbonic acid ; and one is reported in these formations con- 

 taining sulphate of magnesia and iron, with chloride of so- 

 dium. Near Warren's Mill, on Mackey's Creek, is a spring 

 containing sulphate of iron and sulphuretted hydrogen. In 

 Tishamingo, Itawamba, Chickasaw, and Tippah counties, 

 there are springs which contain the salts of iron, lime, mag- 

 nesia, alumina, and soda. 



"The Eocene formations of this State contain more mine- 

 ral springs than any of the other rocks." At LAUDERDALE 

 there are five or six sulphur and chalybeate springs. They 

 are near the line of the Eocene and Miocene formations. 

 These are copious founts, and, according to Mr. Harper, 

 " create, morning and evening, in the surrounding region, a 

 a sulphuric atmosphere."* Quitman's Red Sulphur is valu- 

 able, containing sulphuretted hydrogen, lime, magnesia, 

 chlorine, and apocrenic acid. Mineral springs are also re- 

 ported in the Miocene of Mississippi. 



* Harper gives a minute analysis of the Lauderdale Springs. He 

 represents them as containing of volatile ingredients, sulphuretted 

 hydrogen, carbonic acid, oxygen, nitrogen, carburetted hydrogen ; 

 acids, sulphuric, carbonic, silicic, apocrenic, also, chlorine, iodine, 

 bromine, inappreciable (!!!) bases, iron, lime, magnesia, potassa, alu- 

 mina, soda, and ammonia.
