This is one of the permanent observatories situated on the 

 coast of the Japan Sea in the province of Noto. As will be seen 

 from the map, the building is at the eastern side of a promontoiy 

 near the town of Wajima. 



The series of marigrams to wliich the harmonic analysis is 

 applied are of the years, 1901-05. The principal oscillations of 

 the water here are veiy small, but are accompanied with secondary 

 oscillations of comparatively large amplitude. 



The highest high-water recorded here was 3.12, referred to 

 the zero-point of the instrument, and occurred on August 16, 1901. 

 The lowest low-water recorded was 4.33, referred to the same 

 origin, and occurred on March 27, 1905. Thus the extreme range 

 is 1.21 metres. 



The height of the mean sea-level, referred to the zero-point 

 of the instrument, is obtained for each year-series as follows: — 



1901 3r715 



1902 3.728 



1903 3.714 



1904 3.697 



1905 3.707
