[Dactyloscopy undifferentiated oligophrenia].
The paper deals with a study of dematoglyphics in 458 oligophrenic patients (265 boys and 193 girls) from 7--18 years of age and 373 normal children of the same age. In all the ill boys, irrespective of the degree of mental retardation there was a decrease of arc patterns and an increase of the whorle frequency. In girls with oligophrenia in the degree of debility there was a significantly lower amount of arc patterns and an increase of whorles, the frequency of loops did not differ significantly with that of the control group. In girls in whom the oligophrenic defect was of the degree of imbecility or idiocy there was a more frequent amount of arc and whorle patterns at the expense of a decrease of loop patterns, while in the control group there was a somewhat more frequent amount of arc an loop patterns and less frequent--of whorles.
