(2) and (3) Calvaria in the Pathological Museum of University 
College, Liverpool. 
Among the osteological series in the Pathological Museum we have found 
two calvaria, with symmetrical perforations of the parietal bones. There is 
no history attached to the specimens. 
No. 306 (Fig. 5) is a calvarium sawn off above the lambda. The coronal 
suture is well marked, and there is a metopic suture. The sagittal suture is 
visible, except for about 25 mm. near its posterior end. In each parietal 
bone there is a perforation separated across the middle line by a bridge of 
bone 19°75 mm. in its narrowest part. The sagittal suture is obliterated in 
relation to this bridge of bone, which is grooved on its under surface for the
