The injection of air into the ventricular cavities for the purpose of ventriculography, devised by Dandy, has been of great value for the localization of otherwise unlocalizable intracranial new-growths. Those who have used the method have realized that only gross deformities and alterations in the size and shape of the ventricles were being recognized, that the interpretation of the roentgenograms was often difficult, and that, in all probability, there were slight but important changes in the ventricles secondary to tumors of which little or nothing was known.
Up to the present time, no careful study of the finer changes in the ventricles in tumors of the brain has been published, and we felt that such a study was needed.
In the investigation of the subject, we considered it necessary (1) to make actual casts of the ventricles of patients who had died from brain tumors; (2) to compare these casts
