132. SlDEIilTE. 
In line rhomboliedral crystals, formerly at the McCulloch, the North 
Carolina, and several other mines in Guilford county, where it occurred 
in considerable masses in the vein. In the same manner it is of trequent 
occurence in many of the gold veins of the State, especially in those 
which carry copper. It often forms almost the whole mass of the veins, 
frequently, however, decomposed into liinonite, which still retains its 
rhomboliedral form, tor instance, at Conrad Hill, in Davidson county, and 
Gaston county, at some of the mines in Randolph county, and the Cosby 
Mine,* in Cabarrus county. In smaller quantities it has been observed 
in Stokes county, and some of the mines in Mecklenburg county. A 
white cleavable variety occurs at the Rudesill Mine, near Charlotte. 
The earthy and argillaceous varieties ot siderite fgqm large beds in the 
triassic coal strata of Chatham county,* and constitute the so-called black 
band or ball ore at Fartnville, Egypt,* the Gult,* etc., in Chatham county. 
133. ItnoDociiiiosiTE. 
In small globular pink and rosered concretions, with earthy manganese 
near Franklin, Macon county, also mixed with magnesite, talc, etc., in 
compact and granular masses at the McMakin Mine, Cabarrus county. 
131. Cekussite. 
The most beautiful crystallizations, single individuals as well as twins, 
have been found at Silver Hill, immediately after the discovery of the 
mine, also white, yellowish and greenish white, compact varieties, fre- 
quently highly argentiferous. A very interesting occurrence at the same 
mine is cerussite, pseudomorphous after pyrite. Yellowish white colum- 
nar cerussite occurs in Gaston county. Rhombic prisms with octahedral 
planes, together with imperfect crystalizations and earthy masses, are 
found at Clegg's Mine, Chatham county. At Elk creek, in Wilkes 
county, earthy cerussite has been observed coating galenite. It is also 
found at the Baker Mine,* in Caldwell county, and at Murphy, Cherokee 
county. 
135. Malachite. 
Malachite, in its varieties, fibrous, compact and earthy, being the result 
of the decomposition of other copper ores, is fouud in association with
