METEOROLOGY IN JAPAN 141 



consist of the chief, the meteorologists, the assistants and the clerks. 

 The chief and meteorologists are appointed with His Majesty's approval, 

 and the assistants by the governor of the prefecture. Stations are 

 inspected about once every three or four years by the staff of the Central 

 Meteorological Observatory. 



The Central Meteorological Observatory of Japan, which is situated 

 at Tokyo, is the center of our meteorological service. Most of the im- 

 portant investigations are conducted by its staff either at this observa- 

 tory or elsewhere. It is organized into four divisions: (1) cabinet of 

 the director, (2) service of predictions, (3) service of observations and 

 (4) service of statistics. The present director of the observatory is 

 Professor K. Nakamura, D.Sc, a former student of Professor von 

 Bezold at Berlin. The service of predictions has been for the last 

 twenty-five years in the most able and experienced hands of Professor 

 Y. Wada, who is now completing the organization of the similar meteor- 

 ological service in Korea and Manchuria. Dr. T. Okada now succeeds 

 Professor Wada as the chief of the service of predictions and Dr. W. 

 Oishi is chief of the service of observations at the Central Meteorolog- 

 ical Observatory. 



The instrumental equipment of this observatory is so complete that 

 it may well be called a meteorological laboratory. Here one can execute 

 meteorological research in barometry, thermometry, hygrometry, nepho- 

 scopy, pluviometry, anemometry, actinometry and other lines. There 

 are various instruments and apparatus for verifying the meteorological 

 instruments that are to be distributed to all stations or elsewhere. The 

 observatory also undertakes observations on seismic, magnetic and elec- 

 trical phenomena. For seismometry, there are the Gray-Milne seismo- 

 graph, the Ewing seismograph, Tanakadate's seismograph, the Milne 

 horizontal pendulum, the Omori pendulum. Seismic observation and 

 study form an important feature in the meteorological service of Japan. 

 Each station is equipped with a set of seismographs. Professor F. 

 Omori, of the Tokyo Imperial University, is most active in seismological 

 research, backed by the Imperial Earthquake Investigation Committee, 

 which is composed of such eminent men as Baron Kikuchi and Pro- 

 fessor Tanakadate. For further information along this line of work, 

 the reader should consult Baron Kikuchi's monograph, ' Eecent Seismo- 

 logical Investigations in Japan,' which was originally prepared as an 

 address to the International Congress of Arts and Science (in 1904) at 

 St. Louis. For the measurement of atmospheric electricity, there are 

 used at the Central Observatory Exner's portable electrometer, Mas- 

 cart's self-registering electrometer, Kelvin's collector, etc. The hourly 

 values of electric potential are published in the annual reports. 



The periodic publications of the Central Meteorological Observatory 

 are the daily weather-map, the monthly report, the annual report and 

 the monthly weather review. In addition to these, the Bulletin of the
