• Since 1904 a new system has been adopted, a special inspector being
appointed to carry out the duties under the Sale of Food and Drugs
Acts, instead of, as formerly, several of the district inspectors doing
this work.
A glance at the above table shows that the improvement
manifested during the last few years in the percentage rate of
adulteration was on the whole maintained during 1911. These
results are the more satisfactory having regard to the increased
number of samples taken in each year since 1906, and is largely
the result of the policy of the Council in enforcing their powers
under these important statutes in the interest of the public health
of their district.
Of the total number of samples purchased under the provisions
of these Acts during 1911, 635 (i.e. 63.5 per cent.) were milk samples.
Of this number 68 (i.e. 10.7 per cent.) were reported by the public
analyst to be adulterated. During 1910, 642 of the samples purchased
referred to Milk of which 54 (i.e. 8.4 per cent.) were found
to be adulterated.
The nature of the adulteration in the adulterated samples of
milk were as follows :—
1. Extraneous water (43) varying from a miniumum of 1.5
per cent, to a maximum of 15-0 per cent., viz., 1-5, 1-5, 1-5,2-0,
