Book Description
Excerpt from Popular Lessons in Astronomy, on a New Plan: In Which Some of the Leading Principles of the Science Are Illustrated by Actual Comparisons, Independent of the Use of Numbers Although many elementary works on Astronomy are already before the public, yet it is believed there is none in which the various magnitudes, surfaces, and distancescf the heavenly bodies, are presented to the eye of the learner by actual comparisons the only way, perhaps, in which young pupils can be expected to form a correct idea of them. This the author has attempted in the following pages. The comparative diameters, surfacesand distances of the different planets, are all drawn, - in the plates according to a fixed scale of geographical miles; the surfaces of the planets are actually reduced to square measure, and drawn in proportion to each other and the' sun so that the youngest pupil, by a mere glance of the eye, is enabled to form a correct idea of their respective magnitudes. A similar plan has been pursued, in regard to the division of the Earth into Zones, and with respect to the extent of the five great Continents of our Globe. The Appendix contains an exposition of the population of America, Europe, Asia, Africa. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
