Abstract
WORK undertaken in this Laboratory suggests that certain species of diatoms, which are the normal constituents of the slime film which forms upon a submerged surface in marine waters, contain copper, far in excess of the amount usually considered lethal for unicellular Algæ. (Half to one part per million is usually sufficient to remove algal growths from reservoirs.) Large colonies of marine diatoms were gathered freshly during the spring maximum of 1946, from a raft located in Chichester Harbour. Sixteen samples were examined : Nos. 1–12 inclusive were species which live in frondose colonies of mucous filaments, 5–10 cm. in length ; samples Nos. 13–16 inclusive were species which grow either upon mucous stalks or embedded within a flat film.
