Abstract
THE dilution technique is not entirely satisfactory in studying soil algæ. There is no universal medium for their growth, nor can we assume that all species will grow on any artificial medium now in use. The slow growth of algal colonies involves delays of up to two or three months, causing inconvenience in routine work. Filamentous and colonial algæ introduce further difficulties. A single filament or colony can give one or many colonies according to the number of viable pieces formed from it during dispersion. Available data on the number of algæ in the soil cannot therefore be regarded as absolutely certain.
