H. A. Pels and J. H. Oort have discussed the results of a search for fainter Hyades that had been made by G. Pels. The search extended over a region of about 15° radius around the Hyades centre. It was made from proper motions determined from a comparison of Astrographic Catalogue positions with those on plates taken with the 34-cm Leiden refractor. The data extend to about 13m. In part of the field comparisons were also made with plates taken for the Astrographic Charts, in order to extend the luminosity distribution to somewhat fainter magnitudes.
