A text-book of the diseases of the ear and adjacent organs . frequency of the coincidence of a disturbance of hearing withleucocythaemia is not as great as that of leucocythasmic retinitis, butis estimated by Yidal and Isambert at about 10 per cent, of all the report of these authors the clinical analysis of the leucocy- LEUCOCYTHAEMIC DEAFNESS. 643 thaemic disturbance of hearing and the anatomical conditions under-lying it, are wanting. The first case of leucocythaemic deafnessobserved clinically and examined pathologically was reported by meat the Otolog. Congr. in Basel in 1885. A man, 32 years old, with a severe type of splenic, glandular and myelo-genic leucocythaemia, had otorrhoea in his left ear for a long time while a suddenly became deaf in both ears over-night about a year before hisdeath.
