The gyrus fornicatus and the precuneus are pressed down-ward, but the cuneus does not appear to be pressed upon or dis-placed. No surgeon can look upon this specimen without a feeling ofregret that he could not have had an opportunity to attempt itsremoval. Its location immediately under the dura, its freedomfrom attachment to the cerebral convolutions, and its moderate size,would have made its removal easy. Its location behind the motorarea is probably the reason that the patients symptoms were notmarked until just before the fatal termination of the disease.

The tumor has beenlifted out of its bed. habits of life and surroundings were such that she would not belikely to call a physicians close attention to the early manifesta-tions of cerebral disorder, if, indeed, these were apparent to thepatient herself. A large opening made with trephine, gouge orsaw, followed by a similar incision of the dura, would have enabledthe operator to lift the tumor from its bed without hemorrhage ordisturbance of tlje cerebral convolutions. The growth is probablya libroma. The occurrence of right-sided paralysis seems rather curious, butDr. Robinson states that he is sure of the correctness of this note,for he remembers that she used her left hand during her final ill-ness. There is no evidence of a second tumor on the left side^ 404 ROBERTS : CO>fTRIBUTIONS TO BRAIN SURGERY.
