The elements of astronomy; a textbook
A school astronomy textbook by Princeton astronomer Charles A. Young, revised by Anne Sewell Young and published by Ginn and Company in 1919 for American secondary and college students. The plates are engraved star charts: gridded rectangles of right ascension and declination, dotted stars graded by magnitude, dashed constellation boundaries, the ecliptic cutting across, and named stars in italic type.
