It is thus evident that the comparatively large amount of organic
contamination in the Thames derived-water noted in 1891 has been
very nearly equalled during the flood of November last, whilst the
maximum impurity in the Lea was much smaller than that noted
in 1891, and was oven slightly less than in 1893.
