摘要

IT has long been known that mongolian imbeciles are i":req1.1ently 'l)om to elderly parents, and practically every observerl who has recorded any large number of cases, has oome to the conclusion that either the age of the parentsat·the-birth of the-cbild.or ultimogeniture is an aetiological factori. The present communioation is not concerned with the problem of how far order of birth may be an acoessory causative faator, lmt is confined to aonsideration of the relative effects of paternal and mate:rnaJ. age.
