We have observed 23 sources from the Max-Planck Millimetre Bolometer (MAMBO) array 1200-mum survey with SCUBA at 850 mum, detecting 19 of the sources. The sources generally have low values for the ratio of 850- to 1200-mum flux. Two possible explanations for the low values are either that the sources are at very high redshifts or that the global properties of the dust in the MAMBO sources are different from the global properties of dust in low-redshift galaxies. If the former explanation is correct, we estimate that 15 of the MAMBO sources lie at z > 3.
