Fractures of the Skull. 51 



3. 31. Depressed Fracture of the Vault of the Skull, with 

 a Fissure passing- into the Base.— Calvarium of a boy 



— macerated — showing a fracture of the frontal and right 

 parietal bones. 



" This boy was brought into the hospital in a state of death-like 

 insensibility, and his head misshapen. An effusion upon the temple 

 tempted me to make an incision through the scalp, and there I found the 

 bone shattered. I applied a small trephine, and afterwards the cranium 

 saw, and took away the pieces of broken bone, and washed out the 

 coagulum from under, but there followed no amelioration of symptoms. 

 The boy died, and now it is seen that a fracture extended round the fore- 

 head to the base of the skull, and that the injury was too great to allow 

 of the expectation that the patient could live. " 



From the depression behind the seat of fracture, and from 

 the horizontal fissure in the frontal bone, the injury must have 

 been very severe. B. C. 1. 2. M. 2. 



3. 32. Compound depressed Fracture of the Skull, with 

 Fissure. — Calvarium of a boy — macerated — shovping com- 

 minuted fracture of the right parietal "bone, with a fissure 

 running backwards into the occipital bone. 



"The boy was kicked by a horse. The fragments were depressed,, 

 and so tightly wedged down that the trephine had to be twice applied 

 before they could be elevated. The dura mater was torn, and the brain 

 lacerated by the injury. Some brain matter escaped. The patient remained 

 insensible, had convulsions, and died in five days after the accident."
