(Grateful appreciation goes to Lowell Detloff who assisted in the statistical analysis and machine processing of the data. We are deeply indebted to the California analysts for the high rate of response to our request for participation in the study. Dr Albert Kreinheder merits our special thanks for arranging for the distribution of the surveys and check-lists to the Los Angeles Society. It also gives us great pleasure to express our gratitude to the C. G. Jung Institute of San Francisco for a grant from the Ernst and Eleanor van Loben Sels Scholarship Fund for financing an ongoing investigation of which this study is a part.)
