Publisher's Synopsis
Excerpt from Johnston's Handbook to the Celestial Globe
It is very necessary that the observer should have an Almanac giving the data necessary for determining the posi tions on the Globe of the Sun, Moon, Planets, and Stars. He should also make himself perfectly familiar with the different Kinds of Time. A brass Quadrant will also be found useful for ascertaining the Altitude and Azimuth of a heavenly body at any time. Only the most important problems on the Globe - those involving the fundamental principles of the matter - have been solved, and in a few cases the results are given in sidereal instead of mean time, but these will be found sufficiently accurate for all ordinary purposes. The explanations and instructions are purposely given in simple language for the benefit of those who may not yet be quite familiar with technical astronomical terms.
