The legislature of the state of Ohio have just established a medical college in this city, and have by an unanimous vote passed a law incorporating the Faculty. In the act, Dr. Samuel Brown of Alabama is named as Professor of Anatomy, Dr. Daniel Drake of Cincinnati, Professor of the Institutes and Practice of Medicine, Dr. Coleman Rogers, Professor of Surgery, and Dr. Slack, Professor of Chemistry. The other Professors are to be appointed by the Faculty, and it is believed that Dr. Richardson of Lexington, Kentucky, will be called to the Obstetrical chair. Very high expectations are entertained of the importance of this institution in the west. 20. _Notes on Ohio._ Caleb Atwater, Esq. of Circleville, Ohio, has issued proposals for publishing the above work, (mentioned in our last number) with a prospectus exhibiting its principal features. We doubt not it will contain valuable information concerning a very interesting portion of the United States, and every effort on the part of men of intelligence and enlarged views, to make the western and southwestern states better known, deserves, and it is believed will receive, adequate support. 21. _Discovery of American Tungsten and Tellurium._ Neither of these metals, so far as we are informed, has been announced as existing in either of the Americas. It is well known to mineralogists, that tungsten is very rare, and that tellurium is found only in Transylvania. We have now the pleasure to state that both these metals exist in the Bismuth mine, in the town of Huntington, parish of New Stratford, in Connecticut, 20 miles west of New-Haven. During the examination of some ores, brought to us by Mr. Ephraim Lane, the proprietor of this mine, we obtained the tungsten in the state of yellow oxid, and the tellurium in the metallic state. The tungsten is stated to be abundant in the mine; it is the ferruginous species, known to mineralogists by the name of wolfram. We cannot yet say whether the tellurium is abundant, having obtained it from only two pieces; from these we extracted also tungsten, so that it may possibly constitute a new mineral species. Further particulars will be given in our next Number. 22. _Mr. Sheldon's Application of Chesnut Wood to the Arts of Tanning and Dying._ REMARKS. A considerable time since, we were confidentially made acquainted with the discovery detailed in the following letter. We have repeated the most important of Mr. Sheldon's experiments, both in relation to tanning and dying, and are well satisfied that the discoverer has not overrated, or erroneously estimated, the value of his own results. We are persuaded that the highly _useful_ arts alluded to, will derive important aid from the use of a material so abundant and cheap as chesnut wood. _To Professor Silliman._ _Springfield, Mass. Feb. 27, 1819._ DEAR SIR, I send you a more particular account of the newly discovered properties of the chesnut.
