gives the distance, D, of various stations from the origin and the number of minutes occupied by C and M to 

 travel from the origin to the station. The average velocity D/G may refer to PI or P 2 , while D/M 

 refers to Pa. 



The times at which PL P a , and P 3 would be expected to reach New Zealand and the " Discovery " would 



be ;is follows : 



New Zealand PI 14.51, P 2 15.0, P 3 15.17. 



"Discovery" PI 14.56, P 3 15.7, P 3 15.35. 



From this it appears that with a disturbance of greater intensity than No. 6, PI was recognisable at 



Chris tchurch. 



8. March 28. 



Iii all probability the first entry refers to a shock which had an Antarctic origin. The relations between 

 the times of these two disturbances as recorded in Batavia and by the " Discovery " are somewhat similar 

 to those for No. 4, and one may be the secondary of the other. 



9. April 1. 



At Christchurch a very slight disturbance was noted at 9 12-7. The inference is that the shock after 

 reaching Christchurch had about 9 to travel before reaching the " Discovery," A possible origin would 

 be about W S.W. of New Zealand.
