Excerpt from Results of Double Star Measures Made at the Sydney Observatory, New South Wales: 1871-1881 About 746 of Herschel's stars have been remeasured, some of them many times over, and 350 new double stars have been found. The results are appended, representing in this small compass some measures of angle and distance. For the sake of completeness I have included, in the general list, the few stars mentioned in my paper read before the Society last year. With regard to other matters affecting the observations, I may mention that both the domes are made of thin brass, and the temperature is always very nearly the same inside as it is outside; hence the work could be begun as soon as the shutters were Opened. It has been my practice to observe stars on the meridian, or very near to it, and always taking the R. A. By means of the instrument, the hour circle readings show the distance from the meridian when the observations were finished. In some instances bright stars have been measured during the day-time, but generally the aper ture has been reduced to get rid of the excessive light of bright stars.
