Infrared photometric and spectroscopic observations of IC~1848 from two of the instruments aboard COBE are used to derive physical properties of the dust and gas in the diffuse H II region and in the molecular clouds heated by the cluster of O stars. With its $42^{\prime} \, \times \, 42^{\prime}$ instantaneous field of view, the Diffuse Infrared Background Experiment (DIRBE) provides 9 independent spectral energy distributions from various parts of the region covering the spectral range from 1.25 to 240 $\mu$m in 10 bands. Maps of the dust temperature and column density derived from the DIRBE far infrared observations are presented. A spectrum from the Far Infrared Absolute Spectrophotometer (FIRAS) shows strong [C~II] and weak [N~II] line emission.
