Alterations of Skull from pressure. 417 



6. 525. Skull Artificially Flattened at the Back in Child- 

 hood. — Skull of a young person — macerated, illustrating the 

 above. 



It is said to have come from Mount Lebauon. The alteration in 

 shape is stated to be produced by bandaging the head and keeping the 

 child on its back. 



In this case the flattening is a somewhat vertical one at the 

 back, between the occiput and the vertex. The result is an 

 alteration in shape, almost the reverse of that seen in the 

 previous specimen. The front and top parts of the head are 

 unusually spherical, and the forehead rises abruptly and high 

 above the face. G. C. 3592.

6. 526. Absorption from Localised Pressure from without. 



— Skull-cap — macerated, illustrating the above. 



There is an elongated area of absorption of the outer table, 

 extending over the adjacent portions of the frontal and parietal 

 bones. The portions of the sagittal and frontal sutures, in- 

 cluded in the area of depression, are especially absorbed, so 

 much so in the case of the sngittal suture that it presents an 

 irregular cleft. The condition has doubtless been due to some 

 form of pressure, of which unfortunately no history has been left.

6. 527. Absorption of the Interior. — Portion of a fronta 



bone — macerated, showing an area of absorption on the inside, 

 which has no doubt been caused by some form of pressure.

6. 528. Absorption of the Interior. — Portion of an occipital 



bone, showing unusual depression of the torquelar Herophili, 

 with several eroded pits just below it. Said to be from a 

 tumour of the brain. G. C. 600. a.
