Photometric data from four red-sensitive plates of comet Kohoutek 1973 XII taken at the Cerro Tololo Observatory, already studied by Sekanina and Miller (1976), are used as input to the inverse approach to the Finson-Probstein method (Finson and Probstein, 1968; Fulle, 1987). The results of this application are the time-dependent size distribution and its time-average, the dust mass, and number loss rates and the dust ejection velocity from the inner coma. The fragmentation processes of large dust released at a regular rate, already observed in other comets, are confirmed. From these results, the mass of meteoroids injected by C/1973 XII into bound orbits is computed. The value of about 10 to the 12th g is obtained, in agreement with C/1957 III and C/1962 III, quite far from the about 10 to the 14th g supplied by C/1970 II (Fulle, 1987).
