Excerpt from A Treatise on Astronomy, Spherical and Physical: With Astronomical Problems, and Solar, Lunar, and Other Astronomical Tables The Astronomical Problems in Part III. Remain substantially the same as in the last edition. The table of Latitudes and Longitudes of Places, the tables of the Planetary Elements, and the table of the Mean Places of Fixed Stars, have been replaced by others that are more accurate and more extended. The tables of the Sun's and Moon's Epochs have been extended to 1884. Many new illustrative figures, and several plates of telescopic appearances, have been added. One of the most important of the special improvements intro duced consists in the adoption of the new and more accurate determination of the Sun's parallax, and mean distance from the earth. This is now generally adopted, as one evidence of which may be mentioned its introduction into the computations of the English Nautical Almanac for 1870. It brings with it amore accurate determination of the distances of all the planets from the Sun, and of the satellites from their primaries, and the dimensions and densities of the planets. The present is the first American treatise in which this important advance in exact astronomical science has been incorporated.
