lime from Skrickerum, in Smolandia, Sweden.— 
Red or ruby coppei' ore, compact, foliated, and 
fibrous; one of the more remarkable is the bright

{Case 34.) Ores of copper continued: black cop¬ 
per, massive, and as superficial covering of other cop¬

of crystallized blue ox azure copper, from Chessy and 
the Bannat, combined with various substances, and 
earthy varieties of the same, some of which (called 
mountain-blue) have been used as pigments.— 
Crystals passing from the state of blue copper into 
that of green carbonate (cuivre carbonate bleu £pi- 
g&ne Haihj). —Green carbonates of copper; among 
which are the beautiful varieties of fibrous mala¬ 
chite of velvety appearance, in acicular crystals, with 
carbonate of lead, &c. 
(Case 35.) Ores of copper continued: among the 
specimens of compact malachite , the most beau¬ 
tiful and characteristic are those from the Guma- 
shevsk and Turja mines in the Ural mountains.— 
Anhydrous carbonate of copper.—Werner’s frothy 
copper ore from Hungary.—In this case is also 
placed the copper-green of Werner, by some
