*The figures in this column are based on the Imperial night census, and are obviously misleading.
Unfortunately there are no accurate means of arriving at the number of persons in the City during the daytime.
It will be seen from Table I. that in the course of the seven years 19011907,
7,540 samples have been taken in the City, or upwards of 1,000 samples
annually, and that of these, 580 were found adulterated; the average annual
percentage of adulterated samples during the seven years being 7.7. The
actual percentage of adulteration at the present time is, however, lower
than this, having fallen from 13.11 in 1901 to 6.68 in 1907.
