*LATITUDE AND LONGITUDE OF SOME OF THE PRINCIPAL PLACES IN THE UNITED STATES, &c., WITH THEIR DISTANCE FROM THE CITY OF WASHINGTON.

The Longitudes are reckoned from Greenwich.

The Capitals (Seats of Government) of the States and Territories are designated by Italic Letters.

The Latitude of those places, which are marked with a *, has been determined by the Editor, from actual observations, recently made by himself, and may be relied on within a few seconds. The Latitude of the places marked with a † has recently been ascertained by others, and communicated for publication.

The Longitude of the places marked with a * was computed by the Editor from the observations on the Annular Eclipse of the Sun in February, 1831, after correction for the errors of the Moon's place, as given by the tables of Damoiseau. The Longitude of those marked with a t was determined by the Editor, by chronometers, by comparing the place in question with Washington, the University of Virginia, Philadelphia, or Boston; the position of which is supposed to be correctly ascertained.

The Latitude and Longitude of very many of the places in the following table, where no recent observations have been made, are to be considered only as rough approximations.
