Causes of Deafness

Q. What are the causes of deafness?

A. In ninety-five per cent of all cases the cause of deafness is catarrh which begins in the throat and nose, and which has been neglected until it extended up into the ears. Enlarged ton­sils, snoring, sleeping with the mouth open, are indications of the presence of catarrh.
