Horizontal section showing the position of the cyst and the compression ofthe cerebral hemisphere, and explaining the occurrence of expansile pulsation in thetumour. The marks * * show the extent of the opening in the skull. The tumourbeing fluid, the pulsations of the brain were transmitted in every direction ; hencewhen the finger and thumb grasped the centre of the tumour (see arrows in thecentre of the cyst) they were separated by an expansile pulsation comparable to thatwhich obtains in aneurysm. kept quiet under morphia ; she is more exhausted andher pulse is weaker.
