convince any one of the enormous quantity of Sprudel 

 water running to no purpose into the river. Klaproth 

 calculated approximatively that one could obtain yearly 

 746,884 U. of sulfate and 1,32,923 ft. of carbonate of 

 soda 5 whilst another chymist, Mr. Gilbert, finding 

 erroneous the basis of Klaproth's calculations, esti- 

 mates the yearly quantity of those two salts to 200,000 

 quintals of carbonate of soda. Considering the ad- 

 vantages which might arise from the extraction of 

 such an enormous quantity of soda in a country, like 

 Bohemia, where so much glass is manufactured, 

 several speculators have been struck with the utility 

 of an undertaking, which Mr. Berzelius {Almanach de 

 Carlsbad, 1835, ch. Ill) thinks easy and infallible. 

 The citizens of Carlsbad, it is true, believe still that 

 whatever is extracted from their springs and sold 

 abroad, must be detrimental to the prosperity of the 

 place ; but such prejudices would easily give way to 

 rational consideration.
