MISCELLANIES. 
FOREIGN AND DOMESTIC. 
The following notices are translated from Berzelius’s last yearly report on the 
progress of science; by Dr. Lewis Feuchtwanger of New York. 
1. A new ore of Antimony has been discovered in the Hartz 
mountains by Zinkin, which resembles zinkenite and appears to be 
also a subantimonio-sulphuret of sulphuret of lead with sulphuret 
of silver. 
2. Anew Tenantite has been examined by Hemming from a new- 
ly opened mine in Cornwall which consists of Arsenic, 11.5

3. Vanadiate of lead.—Johnson discovered some species of vana- 
diate of oxide of lead at Wanlockhead in Scotland, one species occurs 
on calamine in form of warts and as large asa pin’s head. It isofa 
dirty white and appears to be dew of a pale red powder, has a res- 
inous fracture and specific gravity of about 7. The other is black 
and looks like earthy manganese; a third has not yet been described, 
but Johnston has sent specimens to the Collection of the Royal Swe- 
dish Academy ; it is regularly crystallized and appears to be a bi- 
vanadiate of the oxide of lead. 
4. Plumbacalcite has been described by Johnson as a mineral 
found at Wanlockhead in Scotland; it consists of carbonate of lime 
and carbonate of lead ; it is crystallized in the primative rhomboid of the 
calcareous spar; it occurs both transparent and opaque and consists 
of 92.2 carbonate lime, 7.8 carbonate of lead. By heat the car- 
bonic acid is evolved, and the mineral assumes areddishcolor. This 
mineral offers an interesting proof of the isomorphism of oxide of 
lead with a rhomboid of carbonate of lime. 
5. Pelokonite.—Richter describes an uncrystallized mineral, oc- 
curring in Chili, with malachite and copper-green under the above 
name, (from rA0¢ brown and xévig powder). It contains phosporic acid 
and the oxides of iron, manganese and copper ; it has a blackish blue
