Since the last meeting of the Union there has been considerable development in the field covered by the Commission, and the following report, which has been drawn up on the basis of reports by the members of the Commission, can only summarize very briefly some important lines of investigation in the recent development.
Photometry and Spectral Investigations in Various Regions of the Galaxy. In addition to the work in Kapteyn’s Selected Areas, systematic investigation is in progress for a great number of galactic regions, and it seems to be an urgent need that such investigations be co-ordinated as effectively as possible in the future.
