We have searched for mm-wave emission from compact objects in two fields, each approximately 1 square degree in size, taken from regions of the sky in which degree-scale structure in the Cosmic Background Radiation (CBR) has recently been reported. The observations were made at frequency of 4.7~cm-1 and with an angular resolution of 1.7' using the Sunyaev-Zel'dovich Infrared Experiment (SuZIE) bolometer array at the Caltech Submillimeter Observatory (CSO). The first field was centered on 14.92hr +82deg (1994.0), one of two regions in which Cheng et al. (1994) identify the signature of an unresolved point source seen during 0.5 degree resolution observations made at 5.6~cm-1 with the Medium Scale Anisotropy Measurement (MSAM) experiment. The second field was centered on 15.47hr +72.4deg (1994.0), part of the Gamma Ursae Minoris (GUM) region where several prominent features have been detected by Devlin et al. (1994) in 0.55 degree-resolution observations made at 3.5 and 6~cm-1 with the Millimeter Anisotropy eXperiment (MAX). We find that there is no point source in either field that can account for the structure observed at 0.5 degree resolution, and that the structure must arise from objects with an angular size greater than 2'.
