sagittal suture (S) begins, and pursues a tortuous course towards 

 the broken edge of the bone. 



The presence of this part of the sagittal suture affords positive 

 evidence of close proximity to the true median line. The anterior 

 extremity of the sagittal suture often becomes deflected a few 

 millimetres to one side or the other of the median line ; but, except 

 in those rare cases where a large bregmatic bone is present, the 

 deviation is never considerable. In the course of an examination

of the collection of crania now in the Anatomical Department 

 of the University of Manchester, I found several examples in 

 which the anterior end of the sagittal suture closely resembled 

 that of the Piltdown skull (fig. 4, p. 94). 



Along the line corresponding to that labelled M in the diagrams, 

 a well-defined longitudinal ridge (fig. 6, r, above) was found upon 

 the endocranial aspect of the frontal bone. Careful examination
