We regret, that we have not the particulars of the ana- 

 lyses before us, that we might see the proofs of the fact, or 

 be enabled to^trace the causes of the fallacy. 

 Fltioric acid in Mr. Berzelius says too, in a letter to Mr. Vauquelin^ that 

 unne. ^^^^ precipitate obtained from urine by limewater, when 



washed and dried, being treated with sulphuric acid, gives 

 out fluoric acid, which corrodes glass. But it requires a 

 pretty considerable quantity of this precipitate, to give any 

 very perceptible signs of it. 

 Mtiriatic acid He adds, that the Swedish chemists have never been able 

 .nnd srida ob- |q obtain muriatic acid and^ soda by means of the galvanic 

 ^"inTsin onfy pi^^ f'^m water perfectly pure. That they find pure water 

 T.heii ^aii is ^ very bad conductor; but if the least particle of salt be 

 present, the decomposinon is moit lapid, and its acid and 

 alkali are set free.
