Since in 1938 Ephrussi and his coworkers found the existence of facei-forming substance in the nitrogenous extract of Calliphora, some communications appeared successively concerning this problem. In the course of the experiment, Khouvine et al ('43) confirmed that imidazole derivatives, such as hydantoin, histidine etc, being capable of increasing the facet number of Bar eyes in D. melanogaster. Despite the efforts of these previous workers, however, the nature of B^+-substance of this fly has not yet been elucidated. In the present paper many substances including derivatives of imidazole, amino acid and nucleic acid were tested for their facet-forming abilities. Larvae of Bar were raised on normal Pearl's media until fifty hours after hatching, then transferred to Pearl's media containing chemicals in different concentrations to allow their emergence. All the experiments were undertaken constantly at 25℃. Facet counts of the flies hatching out of larvae grown on the experimental media were made, and the results are shown in Table 1 and figures 1, 2 and 3. It is noticeable that urea, uracil and adenosine are very effective. B^+-substance may be one of non-specific substances which are found in the lymph or Lucilia and Bombyx as well as in those of Calliphora or Drosophila. It has been discussed briefly that vg^+-substance may be present in the extracts of Lucilia and Bombyx.
