Excerpt from Catalogue of Stars Observed at the United States Naval Observatory: During the Years 1845 to 1871

The Right Ascensions of a Canis Majoris and of a Canis Minoris, for this Table, were obtained by using the annual variations and value of P, given by Professor New comb in Appendix I, volume for 1870, of the Washington Observations; the place 'of a Canis Majoris differing from the place given by Professor Newcomb.

The Right Ascensions of the stars whose places are given for 184 5, are, with two or three exceptions, those given in the British Nautical Almanac for January 1, 184 5, and the observations were reduced to the beginning of that year. For the years 1846, 1847, 1848, 1849, and 18 50, the stars whose places were used are given in the British Almanac for 18 50, and all the observations were reduced to the beginning of 1850. The stars observed in 1858, 1859, 1860, and 1861, were reduced with the places given in the British Almanac for 1860, and the observations were reduced to The stars observed in 1862, 186 3, 1864, and 186 5, were reduced with the places in Table I for 1860, and the observations were reduced to The stars observed in 1868, 1 869, 1 870, and 1 871, were reduced with the list of the American Ephemeris without the 001rections of the volume for 1869; and for 1870 and 1871 these corrections have been eliminated for the stars to which they belong. The observations from 1865 to 1871 were reduced to 1870. O.
