The first part of this work, described in Part I, consisted of experiments on the growth and behaviour of algae in tubs and tanks; this investigation, which was carried out in the Botany Department of the University of Reading, was designed as an experimental approach to some of the problems of the ecology of freshwater algae. Most of the previous work on this subject has been directed along two lines. Much of it may be called descriptive ecology - i.e., observations on the changes in the flora of natural bodies of water, often with data for physical and chemical variables over the same period, and attempts to correlata these with changes. in the algal population. The other type of work has consisted of investigations of the behaviour of algae when isolated in pure culture. In the first type of work it has rarely been attempted to alter the conditions experimentally in order to test hypotheses. In the case of experiments in pure culture, the results obtained would appear to be more directly applicable to algal physiology than to the ecology of algae in the field.
