Rivista di astronomia e scienze affini, 1912, a. 6, n. 09 (September)
A monthly issue of Rivista di astronomia e scienze affini, published in 1912 by the Società astronomica italiana with the Turin astronomical observatory for Italian astronomers and informed amateurs. The plates are working line figures: an eclipse totality band ruled in hatching across a gridded map near Quito, orbital diagrams of labelled circles with directional arrows, a plotted magnitude curve on square grid, and a ruled table of planetary elements with Italian column headings.
