their composition. It does not appear that any of them were seen to sall, or 
known to have been accompanied by any meteoric appearances, except in 
one instance, in which a very vague tradition of this kind is mentioned. 
He notices their irregular and fragmentary form and crystalline structure, 
which he conceives evince the agency of intense heat, and show them to be 
fragments of larger bodies. 
The presence ‘of metallic iron in so large a proportion as that in wittoli it 
is found with respect to the other ingredients, he conceives to indicate a 
proof of the absence of oxygen (in its gaseous state, or in that of water) in 
the body from which the fragments are derived. 
The stony portions of the meteorites resemble exactly volcanic products ; 
in which the presence of iron also furnishes a point of analogy. He also 
comments on the usual presence of phosphorus, which is derived from the 
mineral Schreibersite, constantly occurring in these masses. ‘The metallic 
nickel, cobalt and phosphorus show equally the absence of oxygen. Carbon 
is often found, contrary to the assertion of some observers. 
_ The Schreibersite, which is observed as almost constantly present, the 
author remarks, is wholly peculiar to meteorites; no natural phosphuret of 
iron, nickel, or other metai being found as a terrestrial mineral. 
Hence he considers meteorites as having a common origin exterior to the 
earth, which he believes to be from the lunar volcanoes.
