In March, 1923, I1 presented a study of the data discovered in the neuro-otologic examination of eleven verified cases of brain tumor observed at the Massachusetts General Hospital. From these, certain conclusions were drawn.
Since that time the same subject of investigation has been pursued at the Hospital for Sick Children, Toronto. In the last two and a half years, many children have undergone neuro-otologic examination, but in only twelve cases has my examination suggested the presence of an intracranial lesion. Five of these have not come to proof. The seven which have been proved are fully described in this paper.
The cases are presented in the same manner as were those in my earlier paper. Unessential details are omitted, but the clinical records of the seven cases are given in sufficiently complete detail to enable otologists and neuro-otologists to study them intensively.
