Markham, a British geographer who traveled in South America and India in the mid-19th century.

Other reports and memoranda concern Indian coffee plantations, cotton production, oyster fisheries, and irrigation projects. The volume also includes descriptions of the Suez region, Abyssinia, and Bombay. Manuscript notes and translations in the back of the volume largely pertain to South America, including letters to Markham from an acquaintance in Lima, Peru, and notes on the missionary work of Antonio Machoni.
