acid, and not a solution of acid salts." Other acid springs 

 are found in this county. 



Near the village of Medina, in Genesee County, are the 

 "OAKORCHARD ACID SPRINGS." Analyses by Chilton and 

 Emmons give the presence of saline materials with the acid. 

 Chilton's analysis gives free sulphuric acid in the proportions 

 of 82 -96 grs. to the gallon; also, 



Sulphate of lime, 38-60 grs. 



Alumina, 9'68 " 



Magnesia, 8 '28 " 



Protosulphate of iron, 14 '32 " 



Emmons gives free sulphuric acid, to the pint, 31 '50 grs. ; 

 also, sulphate of iron, lime, and magnesia. Other springs 

 give 24 '25 grs. free acid in a pint, and some only 19 '30. 

 The therapeutic properties of these springs are of course 

 derived from their chemical contents. According to Drs. 

 White and Spring, they are practically curative of quite a 

 number of diseases, the catalogue of which they render. 



LEBANON SPRING, in Columbia County, is thermal, its 

 waters being 70 Fahr. It also contains saline impregna- 

 tions and nitrogen gas. 



Besides the springs already enumerated as medicinal 

 waters, there are, in New York, a number of brine or salt 

 springs. According to Dr. Beck, " they show a great same- 

 ness of composition. They all contain chlorides of calcium 

 and magnesium, with common salt. They also contain bro- 

 mine and iron, and are of great value, the State deriving 

 considerable revenue from the salt springs of Onondaga 

 County." 



Springs containing nitrogen gas are found in Seneca, 

 Rensselaer, and Franklin. 



The FREDONIA SPRINGS, as observed, are highly charged 

 with carburetted hydrogen. This gas occurs in quantities, 

 and is extensively used for ordinary purposes of illumi- 

 nation.
