Photometric UBVRJHKLMNQ observations of CH Cyg and TX CVn obtained with the 1.25-m reflector telescope at the Southern Station of the Shternberg State Astronomical Institute during spring and summer, 1981 and 1982, are reported. The spectral distribution of the IR flux attributed to the CH Cyg dust shell is found to be consistent with heating by the source of UV excess (a hot spot on the M6-giant central star or, more likely, an accreting hot dwarf), and a model dust shell comprising an inner layer with temperature 600 K and mass 3 x 10 to the -7th solar mass at 40 central-star radii and an outer layer with temperature 250 K and mass 10 to the -5th solar mass at about 500 central-star radii is proposed. The presence of a dust shell with luminosity 10 to the 35th erg/sec, average temperature 600 K, and mass 10 to the -8th solar mass is confirmed for TX CVn.
