In order to confirm the localization of intracranial foreign bodies from headinjuries, and to examine the relations between the localization of intracranial foreign bodies and clinical symptoms, findings of E. E. G, etc., the author investigated the precise localization of intracranial foreign bodies, and reached a conclusion that tomography is the most useful one for the purpose. He examined the simplicity, reliability, possibility of description, and application of the method of tomography, which will describe foreign bodies on the plane coordinates, and will locate them by the angle and distance from certain point. In the diagnosis or operation of cases with intracranial foreign bodies, form and situation of the foreign bodies in the space should be preliminarily presumed by means of stereophotography, and if possible, their size and distance should be measured. Then the tomography is conducted and it will show us the intracranial foreign body and the suggested point of surgical invasion, if it is necessary. The preparatory measurement, and the methods and techniques of tomographing were thoroughly examined and the measurable and fixative apparatus of cranial tomographing were designed. In future, the advance in tomographing methods and techniques will enlarge the power of cranial tomography, and will enable us to investigate directly tumors, transformations of ventricles of brain, etc., beyond the concurrent conjecturing indirectly intracranial changes by the anatomical research of cranial forms or the ventricles of the brain.
