Summary Briefly, then, the anatomical features which together strongly suggest mongolism in the Saxon child are: (1) Microcephaly, as shown particularly by vault length, breadth, and cranial capacity. (2) Hyperbrachycephaly, the index being abnormally high for an Anglo‐Saxon (whether child or adult). (3) Small sphenoid body and high angle of the basi‐occipital. (4) Thinness of the cranial bones. (5) Small maxilla but fairly normal mandible size. (6) Minor anomalies of the dentition.
