upward slant of the orbital plates and prominence of the frontal 

 hones. The frontal suture is persistent, and all the other 

 sutures are distinct, although they have apparently been closed. 

 There are numerous, wormian bones at various points. A large 

 number are in the region of the lambdoidal suture, and at what 

 should have been the posterior inferior angle of the parietal 

 bone on each side. One large one occupies the position of the 

 anterior fontanelle, and two others, lying to the right of the 

 sagittal suture, form a continuous chain with those at the apex 

 of the lambdoidal suture. F. P. C. 907. 



6. 534. Chronic Hydrocephalus. —Plaster cast of the skull of a 

 child, greatly enlarged by hydrocephalus. 



The enlargement is greater on the left side, due apparently 

 to a flattening of the skull from right to left. G. C. 3488. 



6. 535. Advanced Hydrocephalus. — Plaster of Paris cast of 



the head and shoulders of a child who died of hydrocephalus. 



There is an enormous enlargement of the skull, with 

 numerous irregularities of the surface. The head, which 

 measures thirty and a half inches in circumference, is, if 

 anything, more hemispherical and less flattened at the top than 

 is usual in such cases. B. C. v. i. M. 21. 



6. 536. Hydrocephalus with Enormous Enlargement.— 



Plaster of Paris cast of a head, illustrating the above, showing 

 Hydrocephalus. 



The following inscription is on the back of the cast : 

 " James Cardinal, born at Cogokstall, Essex, 27 years old." 



The upper part of the skull is enormously enlarged, 

 measuring thirty-six inches in circumference. It bulges some- 

 what towards the right side, and is flattened on the top. 



G. C. 3487.
