40 S- Nakamnra and K. Honda : 



The nodal lines are drawn in Fig. 2, and sliow that when the level 

 is rising at Shiotsu and Nagahama, it is falling at Chömeiji and 

 Imazu. The limnograms obtained at these stations tend to 

 confirm this fact in the actual case, but owing to the presence of 

 other motions it can not be affirmed with certainty. It is proper 

 to call it a binodal seiche of tlie north basin exciting a uninodal 

 motion in the south basin, rather than to call it a transverse 

 seiche of the lake. 



Though other motions with shorter periods, e. g. 9.4 and 8.5, 

 were very prominent, yet they can not be identified with the 

 actual motion.
