mucosa or of the nails. Four women had taken iron tablets for long periods, but not for the six months previous to this investigation. During this time they had not observed any change in the ozaena. The Table contains the results of the haematological investigations. All patients had haemoglobin, haematocrit, and red cell count within normal limits. Serum iron was normal in eight patients, and all had normal total iron-binding capacity. One male patient (Case 8) had a serum iron of 75 ftg./100 ml. and a total iron-binding capacity of 280 tug./100 ml., with a saturation index of 27, but with high values for haemoglobin and red cells. The iron content of his marrow was low, but iron was definitely present. Therefore, in spite of the reduced serum iron, we conclude that he was not iron-deficient.
