Case 1 continued. Native copper: among the specimens of this 
which present a great variety of forms besides the crystallized, such as 
dendritic, filiform, &c., may be particularized the mass from Hudson’s 
Bay, (found by Mr. Hearne, and described by him in his Journal,) 
and that from the mountains separating the Quananger and Alten 
Fiords in the north of Norway.— Native lead , in lava : to which is added 
a medal cast in that metal as ejected by Vesuvius in 1631_ Native 
bismuth , massive, disseminated, and dendritic, in jasper, &c. : to which 
are added, specimens exhibiting the artificial crystallization of the same, 
produced by the sudden cooling of the melted metal. (In this case is 
also placed a specimen of artificially produced titanium , crystallized 
in cubes, from the smelting furnace of the great iron works at Mer¬ 
thyr Tydvil in Wales.) 
Case 2. Native silver : among its varieties may be particularized 
those exhibiting the various forms in which it most frequently occurs, 
such as moss-like, wire-shaped, filiform, dendritical, branched, den¬ 
ticular, massive, Sec., particularly from Kongsberg, Saxony, and the Hartz 
(the latter presented by His Majesty George IV.), many of which are 
aggregations of minute crystals.— Native mercury , and hydrarguret of 
silver or native amalgam; the former chiefly as globules, disseminated 
in cinnabar, sparry limestone, &c. ; the latter crystallized in perfect 
and modified rhombic dodecahedrons, globular, &c., chiefly from 
Morsfeld and Moschellandsberg in the ancient Palatinate; (to which 
are added some figures and ornaments moulded and modelled 
in amalgam, by the miners of Mexico.)— Native platinum , massive 
a.nd as grains: rock specimens of the formation in which it occurs in 
the Ural, Siberia, &c. (a coin of the Siberian platina, struck at Peters¬ 
burg).— Palladium and osm-iridium in a wrought state. — The irite of 
Hermann, found as minute scales in hollows of large lumps of platina 
and in the platina sand of the Ural Mountains.
