 J. W. BARKER, Esq., Secretary Salt Company, Onondaga : 



Dear Sir: Herewith I send you my analysis of the speci- 

 mens of "Factory Filled" Salt, which were left with me by 

 your agent, Mr. Belden. 



ANALYSIS. 



Chloride of Sodium, (salt,) 97.600 per cent. 



Sulphate of Lime, (combined,) 1.124 



do. do. (free,) 227 



Sulphate of Magnesia 077 



Carbonate of Lime 162 



Chloride of Calcium none 



Chloride of Magnesium none 



Water 810 



This is a remarkably pure specimen of Salt, 

 chloride of calcium or magnesium. 



These chlorides cause salt to absorb and retain moisture, 

 and are by far the most active in their properties of any of the 

 foreign substances usually found in common salt. 



A satisfactory evidence of the purity of salt is its dryness. 

 I have had this specimen in a wooden salt box for four months, 

 and still it loses less than one per cent, of water by heatins: it 

 to melting. This is far less than in any other specimen of On- 

 ondaga Salt that I have ever tried. 



By the following analysis of a good specimen of " Ashton 

 Salt," you will be able to compare the purity of the two kinds :
