died within a short period of admission to hospital, the tumours being verified post-mortem. In summarizing these findings it would appear that abnormal mental phenomena may be present in certain cases of cerebral tumour without definite localizing signs. In this series no physical signs were apparent in seventeen per cent., and in an additional forty per cent. these signs were vague and indefinite. Mental symptoms are much more frequently associated with supratentorial growths, especially when such involve the left side. The form of the symptoms depensds to a greater extent on the type of personality and the rate of growth of the tumour, rather than upon its location. In slow-growing tumours changes in the personality are conspicuous; there appears to be, as it were, a release phenomenon. In rapidly-growing tumours, disturbances in the intellectual functions are marked and personality changes slight. In such cases, however, the mental changes may be indistinguishable from those the result of other organic lesions. It would appear that no mental syndrome can be associated with a lesion of any one area of the brain.
