MU'RIA, j! Muriat; in mineralogy, a genus of falts, 
of which the generic characters are—Tafte faline ; eafily 
foluble in water, and the folution not made turbid by 
foda; not effervefeing with diluted acids, but effervelcing 
and emitting grey ill-favoured fuffocating vapours in 
ftrong hot fulphuric acid ; changing nitrous acid into 
the nitro-muriatic acid. The Muriats, and the methods 
of combining them, have been fully deferibed under the 
article Chemistry, vol. iv. p. 243 & feq. fo that we have 
little more to do, in this place, than to detail their ipeciiic 
mineralogic characters.
