Its analysis presented silex 33--alumine 15.5--chrome 1.-- iron 14.5--carbonic acid 9., and a combustible substance of a carbonaceous nature. It is thought that this powder had not a volcanic origin, and that the presence of chrome assimilates it with meteoric stones. _Ibid._ 11. _Gnephalium._ Professor Ives has discovered a new species of gnephalium with decurrent leaves, of which a plate and description will appear in our next number. 12. _Augite._ M. Haüy has united the fassalite and the bakalite with the sahlite, a sub-species of augite. (See Mem. of the Museum of Nat. Hist. vol. 3.) 13. _A New Vegetable Alkali_, Has been found by Messrs. Pelletier and Caventon in the Feve St. Ignace and the Nux Vomica. It has been named the vaucquelin, in honour of M. Vaucquelin. (Journal de Physique, for Aug. 1818.) 14. _New Minerals._ Two new mineral species have been discovered, the scorrodite from Schnuburg in Saxony, and the tungstate of lead from Zinnwald in Bohemia. _Ibid._ 15. _New Metal._ A new metal has been discovered by Berzilius, in the mines of Fahlun in Sweden, to which he has given the name of Selenium. _Ibid._ 16. _Pure Alumine._ A large bed of this substance, perfectly pure, has been found at Argenton, Department de L'Endre. _Ibid._ 17. _Collections of American Minerals._ We are informed that under the auspices of Col. Gibbs, a collection of American minerals by states, according to the arrangement of the minerals of the departments of France, in the cabinet of the school of mines at Paris, was begun some time since, at the rooms of the Hist. Society in New-York; and recently in the University of Cambridge. In the arrangement of the latter, he has been assisted by Dr. J. W. Webster, lecturer on mineralogy and geology in Boston. 18. _C. S. Rafinesque, Esq._ We are requested to announce that a Journal of this gentleman's "Travels and Discoveries in the West, will be published this year by Cramer and Spear of Pittsburg, and that the results of his zoological and botanical labours consist in the discovery of about 15 new genera, and 180 new species of plants; about 75 new genera, and 600 new species of animals, whereof nearly 70 are new fishes, 20 new quadrupeds, 30 new reptiles, 112 new shells, 250 new fossils, &c."
