During the past three years, the author has prepared and examined blood smears from schizophrenic children, some of whom had received phenothiazine drugs. The purposes of this paper are as follows: (1) to report the finding and frequency of several types of atypical leukocytes in the peripheral blood of children diagnosed as schizophrenic; (2) to report the frequency of these atypical leukocytes in the peripheral blood of schizophrenic children under continuous treatment with phenothiazine drugs; (3) to show the
