It was also recorded at Nicolaiew, Tiflis, and Hamburg. At Ternati and Halmaheira (Celebes), shocks 

 were felt at 8.35 and 8.4G (see ' Natuurkundig Tijdschrift v. Ned.-Indie,' Ixiii,, p. 194). M-C for 

 Batavia and Manila indicate an origin about 132° E. Long, and 3° N. Lat. A similar origin is obtained 

 from the differences in the value of M, given for these stations. The time of the origin deduced from the 

 observations made at these two places would be 9.23 or 9.22. 



With an origin at 9.22 the times at which we should expect Pi, P^, and P3 to reach New Zealand and 

 the " Discovery " would be as follows : — 



New Zealand Pi 9.32, Po 9.41, P3 9.57. 



"Discovery" Pi 9.36, P. 9.47, P3 10.15. 



The inference is that P^ and P3 were recorded in New Zealand and P3 only l)y the " Discovery."

This shock, which was one of a series, was felt strongly in the Celebes, The time given for a heavy 

 shock at Ternate is 14h. 45ni. 



M - C for Manila, Batavia, and Irkutsk indicates an origin about 132° E. Long, and 3° N. Lat. To 

 reach Ternate, 3° distant, would take 2- 5m. The time at the origin would therefore be 14h. 42 •5m, 

 This time calculated from the Manila maximum is 14h. 42m., and from the Batavia maximum 14h. 41m. 

 The time adopted is 14h. 42m. The region disturbed embrages the whole world. The following table
