Phillips explains how 'notwithstanding the descriptions and drawings of Mars, for which we are indebted to eminent observers, there remains much uncertainty as to the permanent boundaries of the bright and shady parts of the planet, to which respectively, on a first view, we attach, perhaps too readily, the idea of land and seas.' He considers several sketches of Mars. Includes two letters, dated 20 January 1863 and 14 February 1863, and a newspaper clipping.
