Fractures of the Skull. 41 



brain from the foregoing case — in spirit — showing extensive 

 laceration of the right temporo-sphenoidal and frontal lobes. 



As noted in the previous specimen, the injury was received 

 on the left side. This is therefore an illustration of injury to 

 the brain by contre-coup. The under and lateral surfaces of 

 tlie temporo-sphenoidal and frontal lobes are severely lacerated 

 on the right side, while on the left side they are apparently 

 unharmed, except for slight superficial haemorrhages on the 

 frontal lobe, below the points where the bone was broken.

3. 6. Longitudinal Fissure of Calvarium.— Calvarium — 



macerated — from an elderly person, showing longitudinal 

 fracture through the right parietal and frontal bones. 



The symptoms were obscure, and the fracture was not recognised 

 during life. 



Apparently another fracture below the fissure has been 

 present, but the loose piece has not been preserved.

3. 7. Fracture of the Base of the Skull.— Skull— macerated 



— with a quadrant removed from the vault to show the above. 



The fissure, beginning in the left parietal bone, meets the 

 lambdoidal suture, and then continues into the articulation 

 between the occipital and temporal bones on its way to the 

 base. The body of the sphenoid has been fissured right across, 

 and the sutures at the base of the skull generally are loosened.
