(b) Angle's class II.—Postnormal molar occlusion. Appliances in both jaws usually needed ;
treated by fixed appliances and intermaxillary traction. In these cases it has to be ascertained
before treatment is commenced that the parents are sufficiently interested to allow the patients
to attend for a considerable time. Under treatment: 17 cases.
(c) Angle's class III.—Prenormal molar occlusion. Under treatment: 6 cases.
(d) Cases where there is insufficient room in the arch for all premolars and consequent
displacement of the canine teeth. These have been treated by extraction only, the patients being
recalled every three months for examination. Under supervision : 7 cases.
(e) Space retainers, rendered necessary by the early extraction of a permanent incisor, as
for example after fracture, have been inserted in 2 cases.
Two orthodontic sessions a week are held. A maximum of three new cases and ten old
cases is arranged when possible, but, with the growth of the clinic, the attendance of old cases
had to be considerably increased on most occasions. Attendance is excellent, and isolated
failures to attend, when investigated, have always proved to be due to illness.
Impressions for reference models are taken at the first visit, and again when the patient
is about to be dismissed with treatment completed. In cases of protracted treatment, where the
work is done in more than one stage, reference models are also taken at the completion of each
phase, before a new appliance is designed.
Toothbrush drill is always given at the first visit and a toothbrush supplied if necessary.
When a fixed appliance is inserted the patient cleans his teeth before leaving the clinic, to remove
any fear that brushing will dislodge the appliance. Co-operation of patients and parents is
gratifying.
The Council maintains 15 special aural clinics which are under the direction
of Mr. A. G. Wells. Two additional part-time assistant aurists were appointed in
April, 1936, making 10 in all. Particulars of the work carried on at these centres
are given in the subjoined tables:—

The subjoined table gives a detailed analysis of all cases of otorrhoea treated,
showing number of acute conditions, cause of the persistence of discharge in chronic
cases, the number cured, the number referred for operation, those lost sight of and
the numbers still under treatment on 31st December, 1936. This table includes
otorrhoea cases among children from residential schools (not included in table 13
