Scientific paper

Photometric studies of 113 planetary nebulae conducted by Cohen and Barlow (1974) have provided data for a determination of the dust content of these objects. Estimations of the dust content of four planetary nebulae are obtained. In the calculation of the infrared absorption efficiencies for the silicates, values for the dielectric constants employed by Knake and Thompson (1973) are used.
