EXPLANATION. THIS Index is arranged in four columns: the first gives the names of Places; the second the class to which they respectively belong, as Cape, Bay, River, &c.; the third, the Country, Kingdom, or Sea in which they are situated, and the fourth, the Reference Letters, by which their positions on the Map may be ascertained. It will be observed that the spaces between the degrees of longitude on the Map are lettered at the top and bottom with capitals, as A, B, C, &c., and the spaces between the degrees of latitude are lettered on the sides with small letters as, a, b, c, &c., so that if the position of a place be required, first find on the top and sides of the map the letters corresponding to those attached to the name in the Index, then trace these in direct lines to an intersection, and in the square intersected, the place sought will be found. Spanish names, beginning with X or J, may be looked for under either of these letters, the pronunciation of both being the same, and the use of them indifferent. Names beginning with C or K, if not found under one of these letters, may be looked for under the other. Russian, Turkish, and other Oriental names commencing with J, if not four d under that letter, may be looked for under I or Y, the latter of which gives the correct pronunciation. |
