Chemical Analysis of the Meteoric Stone found at Makariwa, near Invercargill, New Zealand, in the year 1879

Extract

As the preliminary examination of the Makariwa stone had already indicated to Professor Ulrich the presence of mineral constituents having the physical characters of olivine, enstatite, glass, a substance resembling glass, nickel-iron, troilite, magnetite, hydrous oxide of iron, and possibly chromite, the quantitative chemical anslysis presented obvious difficulties, among which may be specially mentioned the fact that one chemical element (iron) enters into the composition of each of the above fine-grained and closely intermingled constituents. This chemical examination I was invited to undertake by Professor J. W. Judd, F.R.S., through whom the two fragments of the stone sent to this country by Professor Ulrich have been generously presented to the British Museum.
