Broadband continuum images of the edge-on galaxy NGC 891 at 850 mu m and 450 mu m are presented. These images are very similar to the 1300 mu m and CO line images. With respect to the 850 mu m continuum, CO is strongest in the socalled molecular ring', and weakest at the largest radii sampled. Inside the molecular ring, the CO/850 mu m ratio is somewhat less than in the ring, but higher than in the remainder of the disk. The integrated infrared emission from NGC 891 is dominated by small particles shortwards of 100 mu m. Longwards of 100 mu m, the emission can be equally well fitted by a single population of large dust grains at 21 K, or a bimodal population of grains at temperatures of 18 K and 27 K. The circumnuclear disk is at a temperature of at least 50 K, and probably much higher.
