1. An attempt was made to examine the interaction between body-type, age at menarche, and diagnostic sub-type, using the examining physician's estimate of body-type as data wherever it was recorded. The results indicated that asthenics might well have later age at menarche than athletics or pyknics, but no clear or consistent relation between body-type and schizophrenic sub-type could be extracted (except for a slight excess of athletics among the paranoids). Thus, for these data, age at menarche related to diagnostic sub-type much more clearly than did body-type. Since, the body-type estimates were probably casually made and were irregularly reported, the failure here to relate body-type to schizophrenic subdiagnosis may only reflect inadequate data. However, it is possible, in view of these data, that puberal age might mediate the frequently-claimed relationship between asthenia and certain types of schizophrenia (1) (4), rather than the other way around.
2. For instance, heavy dating tends to be frowned upon in a twelve-year-old, but considered desirable by age sixteen or seventeen.
