This is very similar in appearance to a mushroom, the ex- 

 panded portion overhanging the skull, while the narrow part 

 •I)rojects through the opening in the bone, and is connected with 

 the brain. It is elastic and compressible, destitute of sensi- 

 bility, of very rapid growth, and when cut into, Ls found to 

 consist of cerebral matter and clota of blood. 



Treatment. — All l^at can be done is to cut the tumour clean 

 off, and apply pressure by wet pads, and prevent all excitement. 

 The tumour has a great tendency to grow afresh, and, a? a 

 rule, a fatal termination may be looked for.
