who had it removed, after great labour and considerable expence, 
to his iron-forge. The whole mass was melted, and then placed 
under the hammer, when, to his disappointment, it separated 
into small pieces, which could not be welded together. It be- 
ing considered useless, the whole was thrown into a ditch, and 
covered up. Nogerrath, after considerable trouble, succeeded 
in obtaining correct information as to the spot where the masses 
were burried, and dug up many of them, of which he sent spe- 
cimens to different public collections in Germany. He analysed 
it, and found that it contained nickel and sulphur, but neither 
carbon, chrome, nor manganese. To vindicate the claim of this 
specimen to the title of the largest mass of meteoric iron hitherto 
found in Europe, it may be remarked, that the Pallas iron which 
fell in Russia, weighed 14001b.; that of Hradschina only 
71 Vienna pounds ; the mass called the Cursed Burgraf of 
Elbogen in Bohemia, 191 lb ; and that which was found at 
Lenarto in Hungary, 194 lb. In the new world, it is true, 
masses much larger have been met with, weighing 14,000, 
30,000, and even 40,000 pounds. 
4. Meteoric Olivine of the Pallas Meteoric Iron. — A careful 
analysis of this highly interesting mineral, afforded to Stromeyer 
the following result : Silica, 88.48 ; Magnesia, 48.42 ; Oxidule 
of Iron 11.19 ; Oxide of Manganese, 0.34 ; Alumina, 0.18 ; — 
98.61. The composition is here the same as in common olivine 
and crysolite, with this difference, that the iron is rather in a 
larger proportion than in these minerals, —and the oxide of 
nickel is wanting. It follows from this analysis, that common 
olivine, crysolite and the meteoric olivine, are varieties of the same 
species. 
5. M eteoric Olivine of the Meteoric Iron of Olurnba in South 
America. — According to Stromeyer this olivine, which occurs, 
like the Pallas iron, in cavities of meteoric iron, contains, Silica, 
88.25; Magnesia, 49.68 ; Oxidule of Iron, 11.75; Oxide of 
Manganese, 0.11 ; — 99.79. 
6. Meteoric Olivine of the Meteoric Iron ofGrimma in Sax- 
ony.- — Stromeyer found in this mineral Silica, 61.8 ; Magnesia, 
25.83 ; Oxidule of Iron, 9.12 ; Oxide of Manganese, 9.31 ; Oxide 
of Chrome, 0.33 ; loss during heating, 0.45; = 979^.
