A decorative scroll border contains the title and mathematical data for the solar eclipse of July 25, 1748. Below it is a linear scale titled "Scale of 60 minutes to which the sphere is adapted."

A world map in a stereographic projection showing the Northern Hemisphere, focusing on the Atlantic Ocean and surrounding continents (Europe, Northern Africa, and parts of the Americas and Asia). A dark circular path indicates the region of central annular eclipse, with various isogonic lines showing the phases of the eclipse across the globe. Geographical labels include "Atlantic Ocean," "North Sea," "Europe," "Africa," and "Asia."

A circular diagram titled "Orthographic Projection of the Earth." It shows a projection of the Earth from the North Pole, detailing the path of the eclipse's shadow ("Path of the Center") and the extent of the penumbra. A timeline with Roman numerals (VI through XII to VI) is provided at the base of the sphere to indicate the progression of the eclipse over time.
