No Binding. Condizione: Very Good. Various paginations; three sets of observations. MANUSCRIPT OBSERVATIONS OF NEPTUNE, DIRECTED BY ITS DISCOVERER. A set of original observations taken at the University of Cambridge Observatory in 1866/7, under the superintendence of John Couch Adams. Including observations of stellar occultation, the diameter of the Sun and Jupiter, and the position of various planets, notably including Neptune, of which Adams was co-discover in 1846. Another set of observations of a comet uses the famous Northumberland Equatorial telescope, which is still installed at the Observatory, and was at the time of its construction one of the largest refracting telescopes in the world, with lenses constructed by the French optician Robert-Aglaé Cauchoix. These observations were largely made under Adams' direction by the Irish astronomer Andrew Graham, and formed part of the Cambridge Zone Catalogue, itself a small part of the monumental catalogue of stars (Astronomische Gesellschaft Katalog), the third part of which was published as recently as 1975. Very good condition, with only minor age-toning to the paper.
