S ummary While no report being yet available, a pilot survey on parental sib rank was undertaken for 396 schizophrenics and 447 neurotics by use of the Greenwood‐Yule method. There were significantly more eldests than youngests, in terms, especially, of same‐sex sib rank, among fathers of female schizophrenics as well as among both fathers and mothers of male neurotics when the patients came from large sibships of five or more. Contrarily, as the present authors have reported before in Japanese articles, for both male and female and for both schizophrenic and neurotic patients (numbering 907 and 1351 cases respectively), there were more youngests among patients coming from the larger sibships. It would be premature to come to any conclusions from these findings, which indicated that many problems remained yet to be solved by means of cross‐cultural surveys and clinical studies, etc. Discussion was made as that from the aspects of sibling rank of both the patients and, especially, their parents, and some aetiological factors might have been elucidated for both schizophrenia and neurosis.
