On the Apparent Disc and on the Shadow of an Ellipsoid

This is a page from a Victorian-era scientific journal — specifically a mathematical paper by A. Marth published in Monthly Notices of the Royal Astronomical Society, vol. LVII — not a pulp magazine cover. It presents analytical geometry for calculating the apparent elliptical disc and shadow cast by an oblate spheroidal planet, using trigonometric relations involving eccentricity, planetocentric latitude, and viewing distance. No illustrated cover, no genre fiction, no typography of the pulp tradition appears here. Writing a pulp cover label for this item is not possible; it is primary astronomical literature and would be misrepresented by that frame.
