The study of the soil microflora by direct microscopic examination offers the possibility of observing the activities of the microorganisms in their natural surroundings and the attention of soil microbiologists has been directed along this line from time to time. Rossi (4) and Cholodny (1) working independently proposed similar methods which yield results of a qualitative nature and their methods have come to be known as the Rossi-Cholodny technic. Recently, Conn (2 and 3), Winogradsky (6), and Ziemiecka (7) have contributed to the further development of the method, adapting it to laboratory conditions.
