Extract

As double stars too close for photography must be discovered, before they can be observed, it is only natural to start a report about the progress made in double star astronomy during the last 3 years by mentioning the work done by Dr R. A. Rossiter with the Lamont 27-inch refractor at Bloemfontein. The first results have been published in a Ust numbering 2234 new pairs. Approximate positions are given, but as yet no measures are reported. These pairs are distributed as follows between different Umits of distance. For comparison the corresponding numbers for the 1900 discoveries, previously made by Dr W. H. van den Bos, are added.
