Book excerpt: Excerpt from A Catalogue of the Magnitudes of 1081 Stars: Lying Between -30° Decl; And the South Pole, From Observations Made in the Years 1885-6 The observations on which the present Catalogue is based were made in the course of a voyage to Australia, round the Cape of Good Hope, and back by the Red Sea, including a stay of two months in Australia. The following is an account of the manner in which the observations were made. Before leaving England seven groups of comparison stars were selected from Harvard Photometry, and several hundred observations of the brightness of stars north of south declination 30° were made in the same manner as is described farther on, in order to acquire practice in the work. The star atlas made use of throughout was Proctor's smaller. Star Atlas, with the addition of all the other stars contained in the large maps published by the Society for Diffusing Useful Knowledge. Nearly all the stars con tained in Lacaille's original Catalogue of 1942 stars and lying south of 30° declination were thus included. All the stars observed have been identified by comparison with the maps of the Uranometria Argentina, with the exception of a few stars not contained in that work.
