 This shock was also preceded and followed by minor shocks felt in 

 Wellington at the times shown in the following table : — 



Eriday, August 14th, at 10.45 a.m. 



„ „ „ at 3.10 p.m. 



Saturday „ 15th, at 3.0 a.m., tidal disturbance. 



Sunday „ 16th, at 3.15 a.m. 



„ „ „ at about 11.0 a.m. 



Monday „ 17th, at 9.56 a.m. great shock. 



Tuesday „ 18th, at daylight. 



Wednesday „ 19th, at daylight. 



Telegraph station-masters reported the shock as from the south, but for 

 mechanical reasons we may conclude that their sensation would suggest the 

 opposite of the true direction. 



The periodical character of these shocks was at once evident, and they 

 appear to be in some degree dependent on the period of maximum and mini- 

 mum pressure, as indicated by the hourly fluctuations of the barometer. 



In conclusion, I may add that I have attempted to state facts in a col- 

 lected form, deferring any fuller discussion of the matter until further 

 details are obtained from Auckland and other places, where, no doubt, the 

 tidal disturbances have been observed. 



Second Communication on tlie recent ^artliqualses and Wave PJienomena, 

 \_Reail 1st Sejpteniber, 1868.] 



We have now evidence, in addition to that which I formeiiy collected, 

 that the first wave reached from the Chatham Islands to New Zealand in 

 about an hour and a half, and that it passed on to the coast of Australia,
