The percentage of samples reported by the Public Analyst to be adulterated during the quinquennia 1921 to 1935 and yearly from 1936, is given in the following table.
Year. | Formal samples, (per cent.) | Informal samples, (per cent.) |
---|---|---|
Mean 1921—1925 | 6.4 | 7.4 |
„ 1926—1930 | 3.3 | 2.4 |
„ 1931—1935 | 1.8 | 2.1 |
„ 1936 | 1.1 | 2.2 |
„ 1937 | 1.1 | 0.9 |
The Public Analyst points out that the year under review
yields results closely similar to those of the two preceding years
with a slight improvement in the case of informal samples, and
there seems little doubt that the frequent and crude adulteration
of former times is rapidly becoming a thing of the past.
The following tables give details of the articles of which samples
were obtained for the purpose of analysis.
