We shall choose _Ostrow_, the defective whom we have already tested in arithmetic. He writes the first phrase with one mistake, the second with one mistake, the third with eight mistakes; he is at the level of a child of nine to ten (_vide_ Table, p. 54). He has therefore a retardation of three years. He must be reckoned as slightly feeble-minded.[9]
