In a previous survey of hospital in-patients it was observed that among schizophrenics the earlier born were affected to a greater extent (Rao and Sundararaj, 1964). Following a suggestion by Slater (personal communication) the work was extended and further data collected on a larger number of patients to determine the role of birth order in schizophrenics. The present communication reports the findings.
