2. The lava stream from Mount Eccles is, towards its termina- 

 tion, but little raised above sea level, and, as it is unmistakeably a 

 subaerial flow, it must have been poured forth when the land stood! 

 at nearly its present height. Now, the gradual upheaval of the 

 southern coast of Victoria in late geological times is proved by 

 the presence of "raised beaches" of early pleistocene (or possibly 

 late pliocene) age on the Glenelg at Limestone Creek, a descrip- 

 tion of which has been given by me,* and, as they were deposited 

 when the land stood from 75 to 100 feet lower than now, it follows 

 that the Mount Eccles overflow was a subsequent event, and 

 could not therefore have taken place earlier than the pleistocene 

 period. 



3. The only deposit which can be identified as younger than 

 the basalt is the dune limestone of Nelson Bay and neighbouring; 

 localities, and this, from its being still in course of formation, as 

 well as from other evidence, f must be considered as recent. Im- 

 mediately beneath it lies the basalt, which is, in all probability,, 

 the next older formation.
