* Rerzelius also thinks that the amalgam obtained from the 
reduction of ammonia contains a peculiar metal. This metal, 
che observes, cannot be a simple bedy, since the radical of the 
ammonia is cempound.” 
» M. Freysmuth has discovered columbium in Bohemia. He 
extracted it from a mineral which had been hitherto regarded as 
a native sulphuret of zinc, and also for nigrin, which it resem- 
bies. The author thinks that tantalium and columbium are 
very different metals, notwithstanding the resemblances which 
Wollaston found between them. M. Jacquin has in his posses- 
sion a piece of columbium extracted from this ore. 
M. Michellotti Has dissolved silyer in the simple muriatie acid 
at a boiling heat, and obtained a crystallizable salt soluble in 
water and in alcohol, and which is sublimated after the mayner 
of the muriates called the butyraceous muriates. This gentle- 
man thinks that it is a hydrochloride-oxide, the muriate less 
precipitated being an oxidule. The water is divided more or 
into a portion with excess of acid, and into a portion with ex- 
cess of oxide.
