On the Latitude and Longitude of eighteen additional positions in the North and North-west of the United States. Also a review of two positions (II. and VI.) previously reported. From astronomical observations, by Lieut. Colonel J. D. Graham, U. S. Corps of Topographical Engineers. Chicago, Illinois, June, 1859. To the American Philosophical Society, Philadelphia. 'I wish now to offer a third contribution to the geography of the United States, for publication in the Proceedings of the Society, if deemed acceptable. I will indicate the positions by a continuation from the numbers used in the preceding contribution, (No. 2,) published at pp. 352 to 388, of Vol. VI. of the Proceedings. They are as follows, viz:VII. ASHTABULA, OHIO. VIII. ERIE, PENNSYLVANIA. IX. TOLEDO, OHIO. X. PRAIRIE DU CHIEN, WISCONSIN. XI. DUNLEITH, ILLINOIS. XII. DUBUQUE, IOWA. XIII. FULTON, ILLINOIS. XIV. LYONS, IOWA. XV. ALBANY, ILLINOIS. XVI. CAMANCHE, IOWA. XVII. CITY OF ROCK ISLAND, ILLINOIS. XVIII. FORT ARMSTRONG, ILLINOIS. XIX. DAVENPORT, IOWA. XX. NEW BUFFALO, MICHIGAN. XXI. NILES, MICHIGAN. XXII. ELYRIA, OHIO. XXIII. CLEVELAND, OHIO. XXIV. COLUMBUS, OHIO. I wish, also, to offer a review, for the purpose of verification, of the following positions previously reported, viz:— II. MICHIGAN CITY, INDIANA. VI. MADISON, THE CAPITAL OF WISCONSIN. The instruments used in making the observations were the same as previously used, and described in page 353 of Vol. VI. of the Society's Proceedings. The system of observation was also the same as was described in the previous papers published in that volume. VOL. VII.-D The apparent Right Ascensions and Declinations of the stars observed on, were taken from the British Nautical Almanac, except a few whose apparent places are not given in that Ephemeris. The exceptions are as follows, in relation to which the apparent places were taken from the Connaissance des Temps, namely: 6 Andromedæ # Herculis 3 Cygni For the determination of the longitudes, now reported, two meridians of comparison were used, namely:-1. Chicago. IX. Toledo, Ohio, after its longitude was derived from chronometric comparisons, by means of the electric telegraph, with the meridian of Chicago. The time-observations at Chicago, and the observations both for the time and the latitude at those stations whose longitudes are based upon direct connections with the meridian of Chicago, will first be given. Then the same will be done in regard to the time-observations at Toledo, and the observations at those stations whose longitudes are derived from direct connections with the meridian of Toledo. Finally, the observations will be given that were made for verifying the positions of Michigan City, Indiana, and Madison, the Capital of Wisconsin. The position of the observing station at Chicago, will be shown by reference to the table at page 351 of Vol. VI. of the Society's Proceedings. Observations for the Time at Chicago. 1st. 1853, July 26th. At Chicago Observing Station No. 3, in latitude 41° 53' 46'.3 N.: longitude 5h. 50m. 31s.2 W. of Greenwich.
