Seiches in Some Lakes of Japan.

We probably have here two motions with periods of 31.8 and 9.7 

 minutes. For the former, see the cm-ves in PI IV. 



Funaki. 



The weather was very windy when we reached Funaki to make 

 the observation, and the lake was so much agitated that we could 

 not recognize any regular oscillation excepting a motion with a 

 period of one minute, which however is decidedly no proper 

 seiche. 



Hikoné. 



Here we made three series of observations. The first series 

 was continued for a day from the 20th. to the 21st. of August, 

 The periods observed are

The second series was continued from the 17th. to the 19th. 

 of September. The weather was generally calm, except at the 

 begining of the observations, when we had a strong N-W wind. 

 The following periods were then observed. |
