Like the table for the preceding earthquake, the arcual values for PI increase with the length of the 

 wave path, while chordal values approximate to a constant value. From 99 to 110 the values for PS are 

 above the average. Where wave paths have been suboceanic, amplitudes recorded in Western Europe and 

 in New Zealand have been high, which suggests that an ocean load has a less damping effect than a 

 continental load. (See Time Curve No. 50, Plate 1.) 



September 26, 16.0, to October 3, 2.30, the clock was stopped. 



51. Ortober5. 



An Antarctic disturbance also noted near to its antipodes. 



52. October 6. 



"Discovery" 8.30 to the 7th, 16.0. A rhythmic succession of 5 or 6 large and 9 or 12 small bead- 

 shaped wave groups. Whether these are connected with a severe earthquake which originated in 

 Ferghana, 40 N. Lat. and 72 E. Long., and which was recorded at the Cape of Good Hope, Perth, and 



many other stations, is doubtful.

October 13. From 10.0 to 16.0 the trace was very faint.

The Manila record refers to an earthquake which was felt at Zamboanga arid Jolo Island. 

 The " Discovery " record relates to an earthquake of local origin, but it is very doubtful whether the 

 time of its occurrence is connected with the disturbance in the Philippines. 



October 18 to 22, the line is very faint. From 16.0 to 23.30 on the 21st it is invisible. 



55. October 28. 



Of local origin.
