An introduction to astronomy
A college textbook of astronomy by mathematician Forest Ray Moulton, published by Macmillan in New York in 1916 for undergraduate students. Line diagrams explain orbits, tides and eclipse geometry with labelled points, dashed construction lines and hatched or stippled shading, alongside reversed-out photographic plates of star fields and nebulae; useful for geometric figures, small sun glyphs and white-on-black night skies.
