Furthermore the signs of increased intracranialpressure came on after the growth ])henomena had appeared andtherefore these could not have depended on this general pressureincrease. Another, though very remote possibility, is that the fibersof the commissura habenularum (some of which penetrate and. A transverse sectit/ii uf brain showing the enlarged left cms cerebriimpinging against the stalk of the hypophysis , and against the pinealgland dorsally. The very slight distension of the ventricles is also to beremarked. become part of the pineal gland), in their further course from theglandula habemiUe to the glandula interpedtmcularis as the interi)cduncularis, arc interfered with in their coursethrotigh the crus by the tumor, thus affecting ihe function of thepineal. In such an event, however, all ttimors of the crtis shouldshow similar symptoms—which they do not. These fibers more-over are presumed to be merely vestigial in character. These remarks are of course based upon the assumption thatinterference with either the hypo]>hysis or the pineal gland, orperhaps both, influences the evolution and control of skeletal growthand sexual precocity.
