tration. (e) It is highly satisfactory to be able to report a negative result for the first year
since 1904, when formal samples of milk were first purchased for examination as to the
presence of tubercle bacilli. Since that year the annual percentage affected among 50 samples
obtained, has varied between 24 in each of two series taken in 1925 to about 25 per cent,
in two series taken in 1921. (f) Increased control over imported milk is being attempted by the
Public Health (Imported Milk) Regulations, 1926. Among other requirements, it is now
necessary for any importer of such milk to register with the Local Authority. At the time of
writing this report, none such had registered in the City. (g) Progress continues to be
made both with the closure of houses in the Hutchison Street and Vine Street insanitary
areas. When a tenant of an unfit house leaves, it is not allowed to be reoccupied. The
accommodation which is in course of erection at Shepherdess Walk and Middlesex Street
is now well advanced, and when the dwellings are available the tenants in the insanitary
areas will be removed thereto, and so enable these areas to be properly dealt with.
Accommodation will also be available for many of the occupants of separate insanitary
houses within the City, in respect of which at the present moment, owing to lack of
alternative accommodation, suitable action cannot be taken.
