This earthquake was felt in Southern Japan, and its origin is given by Mi'. A. Imamura as 9° distant 

 from Tokyo, off the south-eastern coast of Kiusiu. From the observations made in Kiusiu (see ' B.A. 

 Ciicular,' No. 6, p. 270), the value M - C for Tokyo and the Manila record, I should place this origin 

 further S.W. from Tokyo, and deduce 2h. 16m. as the time of origin. 



The following table gives the average arcual velocity of propagation : — 



The values for P3 approximate to what we should expect from other analyses. Po was only observed at 

 comparatively few places, while Pi, unless we accept the two low values of 5 • 3 kms. per second, has not 

 been recorded. 



The earthquake is essentially one that only exhibits one type of wave motion, and this was propagated 

 across Europe and Asia, and southwards beyond Australia.
