In the Geological Magazine for December, 1871 (Vol. VIII., p. 570), we reported the return of the Swedish scientific expedition from the coast of Greenland, bringing home a number of masses of meteoric iron, found there upon the surface of the ground, the largest of which was said to weigh 25 tons. In the Report of the meeting of the Geological Society, Dec. 20th, 1871, contained in our present number (see page 88), we give some further particulars relative to this interesting discovery, which has elicited a letter from the Rev. O. Fisher (see GeologicalMagazine for Jan., 1872, p. 47), and a lively discussion at the Geological Society. We are indebted to R. H. Scott, Esq., F.R.S., for obligingly calling our attention to the account of the original discovery, more than fifty years ago, by Captain (now General Sir Edward) Sabine, of meteoric-iron in Greenland, recorded in the Quart. Journ. of Science, 1819, vol. vii., p. 79, with the analysis of the same, previously published, which we venture to think will prove acceptable information to many of our readers.—[Ed. Geol. Mag.]
