In Australia, where any progression of the tidal wave 

 can clearly be traced, the direction is in conformity with 

 the law of the southern hemisphere. On the east coast 

 we have 



h. m. 

 Jervis Bay 817 



Shoal Bay 10 16 



Wide Bay 10 47 



Port Bowen 1 1 32 



Flinders Group ^i 39 



Cape Sidmouth 11 46 



Cape York i 46 



The north coast of Australia appears to he largely 

 affected by the adjacent archipelago ; and along the north, 

 west, and south coasts, detached places have an almost 

 simultaneous hour, overlaid with many irregular hours. 

 On these coasts there is much reason to doubt the accuracy 

 of the data of the Admiralty Tide-Tables, which are taken 

 in great measure from observations of early Australian 

 discoverers. On the west coast, where Engiish settlements 

 exist, the observed tidal hours would interpolate well with 

 those of the east coast, on the theory of a wave revolving 

 round the continent in 1 2 hours 



The middle island of New Zealand, situate in open ocean, 

 offers a favourable instance of conformity with the law; 

 for we have
