COMMISSION 27 OF THE I.A.U. INFORMATION BULLETIN ON VARIABLE STARS NUMBER 117 Konkoly Observatory Budapest 27 December 1965 FAINT SOUTHERN BV-STARS On sky patrol plates, taken with the 10 inch Metcalf of the Boyden Observatory, South Africa, further stars were found whose variability seems to be real as can as be seen from the material available till now. The 10 inch Metcalf has been at the disposal of the Bamberg Observer by courtesy of the Boyden Observatory.
