it consists essentially of the oxldi of uranium ( t'O : ,,l ( i._,i, 
also thorium, lead, and other elements in small amount, 
with, further, from 1 to 2.5 per cent, of nitrogen. It Is the

240. A metal discovered by Klaproth. in 1789. 
in a mineral which had been long known, and 
called pitch-blende, but which was supposed to 
be an ore of either zinc or iron. The metal itself 
WHS first isolated by Peligot, that which Klaproth hud sup- 
posed to be a metal proving, on further examination, to 
be an oxid. Metallic uranium as obtained by the reduc- 
tion of the chlorid has a specific gravity of 18.7, and re- 
sembles nickel in color. Uranium is far from being a 
widely distributed element ; its combinations are few In 
number, and most of them rare. Pitch-blende is the most 
abundant and important of them, consisting chiefly of 
uranoso-uranlc oxid. with usually a considerable j 
age of impurities of various kinds, especially sulphuret 
of lead, arsenic, etc. Cranium belongs to the chromium 
group of elementary bodies. Sodium dfuranate, or urn- 
nium-yellow, Is quite an imi>ortant yellow pigment, w liieh 
is used on glass and porcelain, and in makiuv yellow 
elass. Cranium pigments are much rarer and more ex- 
pensive than those of which chromium forms the essen- 
tial part
