advertence, has now been burning for several years. Besides the 

 usual products arising from the combustion of coal, it exhales 

 a great quantity of muriate of ammonia. Fumes arise from the 

 burning surface of the ground, which condense into the solid 

 salt, and in dry weather the whole surface is covered with it. 

 Some very fine specimens were found within an inhabited house ; 

 and so abundant was the production in the years 1818 and 

 1819, that many pieces were separated from the walls, weighing 

 above 2 lbs. avoirdupois. The ruins of this house, treated in 

 the large way for the separation of the salt from them, gave 

 such results as would have proved lucrative, if pursued. 



In referring to the probable source of this salt, it is remarked, 

 that the water of all the wells on this coal stratum contain, among 

 other salts, a very notable quantity of earthy muriates. — Ann.

11. Waters of Carlsbad. — The waters of Carlsbad, taken from 

 the principal source, have been analyzed lately by M. Berzelius, 

 who finds many substances in them not hitherto suspected. 

 The following are his most extraordinary results : 1000 parts 

 of water gave, 



Sulphate of soda 2.58714 



Carbonate of soda 1.25200 



Muriate of soda 1.04893

12. On the Flowers of the Meadow Saffron, by Mr. Frost. — 

 This last autumn, I made several preparations of the meadow 

 saffron flower (wz,, a vinegar tincture and wine), which have 

 subsequently been administered by several able physicians with 

 whom I am acquainted ; and they have informed me that the 

 preparations of the flowers operate more uniformly and certainly
