Results of astronomical observations made during the years 1834, 5, 6, 7, 8, at the Cape of Good Hope : being the completion of a telescopic survey of the whole surface of the visible heavens, commenced in 1825
This is a mid-nineteenth-century astronomical observation record by Sir John Herschel, published in London in 1847 by Smith, Elder and Co., reporting telescopic survey results from the Cape of Good Hope for specialist astronomers. The plates show faint nebulous sky drawings, a comet path diagram, and a polar orbit chart drawn with fine plain lines and grey wash. A designer might draw on their soft ghostly tonal washes for atmospheric backgrounds, or on the clean geometric orbit lines for diagrammatic layouts.
