The fresh-waters of Japan afford a wonderful opportunity for the 

 enthusiastic microscopist. Conditions under which simple organisms- 

 thrive are not wanting anywhere in that country. Flooded rice fields 

 of the lowlands, cool mountain streams and innumerable lakes, large 

 and small, are teeming with low plant and animal forms. 



To what extent systematic study of the microscopic fauna and 

 flora of the waters of Japan has progressed, under the direction of the 

 eminent biologists of that county, the writers of this article are not 

 able to state. 



With a view of determining the species of Protozoa characteristic 

 of Japan and comparing them with the American forms, microscopic 

 studies were carried on by C. H. Edmondson during July and August, 

 1912, in various parts of the main island. Beginning with Kobe, 

 observations were made through the central and eastern sections of 

 the country and as far north as Lake Chuzenji. 



Material was gathered from rice fields, small pools, streams and 

 lakes. Collections were made from the following large lakes : Lake 

 Biwa, altitude above sea level 328 ft. ; Lake Hakone, altitude 2,378 

 ft. ; Lake Chuzenji, altitude 4,375 ft. Since the survey covered a wide
