24. " Salt from Saltville. Brine as it came from the well, settled 'with lime, 



say 4 quarts to 6000 gallons." 



25. " Salt from Saltville, Brine as it came from the well." 



109. " Salt water taten from a well sunk at Montezuma ( N.Y.), in 1842, 



the depth of 605 feet. This water is fully saturated : one pint of it 

 yields 2112 grains of chlorides of sodium, calcium and magnesium 

 ( See Municipal Gazette, Vol. i, p. 120 )." 



110. " Salt water from a well 400 feet deep, sunk at Lockpit, Wayne coun- 



ty ( N.Y.), about five miles east of Clyde, and near the Canandaigua 

 outlet (See Mun. Gazette, Vol. i, p. 140)." 



111. " Salt water from a well sunk in 1846, near Little Sodus Bay (N.Y.) 



(See Mun. Gazette, Vol. 1, p. 587)." 



112. " Salt water taken in 1 844 from a salt spring in the wilderness in Perry 



township, near the Elver Trent, Upper Canada. This spring is about 

 thirty miles north of Lake Ontario." 



113. "Water taken from the Dead Sea by Fisher Howe, esquire, of 



Brooklyn ( L.I.), January 19, 1850. This water is a little discolored 

 by the bottle in which it was brought."

shington county ( Va.), January 31, 1844." 



115. " Salt from the Great Salt Lake, Utah Territory, obtained by Capt.

For particulars relating to the brines and salt mentioned in the 

 list, reference may be made to the annual reports of the super- 

 intendents of salt springs of New- York for the years 1850, 1851, 

 1852 & 1853 ; also to Dr. Lewis C. Beck's Eeport on Mineralogy, 

 one of the volumes of the Natural History of New- York. 



It will be perceived, in these analyses, that there is no apparent 

 relation between the amounts of sulphate of lime in the different 

 specimens from the same brine. This, however, could not be other- 

 wise ; for the sulphate of lime deposits in a much more rapid ratio 

 than the salt at the beginning of the salt-making process, and of 

 course leaves the salt w^hich forms last much the purest. The re- 

 verse of this takes place in the amounts of the chlorides of calcium 

 and magnesium, as is strikingly apparent in the specimens from 

 15 to 20, where 15 is the one first formed from the brine, and 20 

 the last, and the amount of those chlorides regularly increases 

 from the one to the other. The amount of water, and to some ex- 

 tent that of the earthy chlorides, found in the salt, varies with its 

 age and more or less perfect drainage. In the tables, no mention is 

 made of insoluble matter, dirt, etc. The salt made by artificial heat
