Ear Disease.
The number of children with ear discharge are given in the table.
They are grouped according to age, and as to whether they have adenoids

occasional discharge. Some of these cases were associated with adenoids,

of measles. Most of the cases are of very old standing, and, as a rule, have
had treatment from time to time at a hospital.
Seven children had scars resulting from a former mastoid
operation.
The hearing was interfered with by wax in the ears in the case of
37 children. One child had an aural polypus..

or over were classed as having good hearing, between 15 inches and 8

The table gives the numbers of children over nine years old whose
