“i may also be mentioned, indicative of the occasional, 
localized occurrence, of meres elements in meteoric irons, that 
in cutting a slice from the very compact Burlington, N. Y. iron, 
a single, very symmetrical, drop- daael cavity more than half an 
inch in diameter was disclosed, which communicated by a minute — 
opening with the surface. Its walls are almost perfectly smooth, 
and coated by a brownish black powder, not yet examined. 
Lenarto iron, also a compact one, contained three empty cavities; 
and a third iron of the same character, that from Murfreesboro’, 
Rutherford Co., Tenn., had two small cavities, the one two-tenths 
and the other one-tenth of an inch in diameter. [s it probable 
that these cavilies were i as empty? or if not, with what 
boner sae they occupied ? 
If n rites are, as Baron Reichenbach supposes, san 
repeacninines of the larger planetary bodies, differing fr 
only in magnitudes, the chemical constitution now det out for 
the former, saad perhaps be thought to have a bearing upon the 
views, put forth by Sir Humphrey Davy, in his explanations of 
volcanoes, falative to the condition of the elements in the interior 
of our earth, where, as he van they may still exist to a large 
extent, — an unoxydated st We may at the present moment 
perhaps be said to have found the following metals in our me- 
iets in an unoxydated (and in an unchlotidized) condition: viz, 
Fe, Mn, Ni, Co, Sn, Cr, Co, Ar, K, Na, Ca, Mg, Al, Si, P, S, ©. 
Farther researches will doubtless, soon augment the number.
