Abstract
In January, 1933. the writer began working on a special problem in the identification of the plankton algae of the canal which cuts through the Butler University campus. The primary purpose of the problem is the study of the periodicity of the algae of the canal. It is planned to consider in a later paper this study of periodicity which will include both seasonal and weekly variations which occurred in the kinds of algae and the effect of temperature of water and amount of precipitation upon the algal flora. From January 30 to October 30 the algae from forty samples of water were identified. It is hoped that the later paper on periodicity will include fifty-two samples, a sample being taken once a week at regular intervals,
