It is thus evident that the comparatively large amount of organic
matter in the Thames-derived water recorded in 1894 was not
repeated in the last two years; indeed the proportion was last
year lower than in any year since 1890. The maximum organic
matter in the Lea was also the smallest observed since 1890.
