 the wingless birds, the " Kiwi " and the " Weka," conclusively proves 

 that they wore united, and, " geologically speaking, at no distant 

 date." ' R. E. Jun.

Kotices the views which have been advanced on this subject. No 



general elevation has taken place since the Glacial period ; and if the 



extinction of the glaciers was due to subsidence, then the subsidence 



may be considered as the latest movement which has taken x^lace. The 



auriferous drifts along the coasts, at levels from 50 to 400 feet above 



sea-level, owe their shape to combined marine and fiuviatile action, but 



were deposited before the Glacial period, as they are sometimes covered 



with moraine matter. R. E., Jun.

Records the volcanic strata passed through in sinking a well 212 feet 

 deep at a fheight of 329 feet above the sea-level and 313 ft. below the 

 summit of Mt. Eden. During the exploration, the results of 7 distinct 

 eruptions were passed through, consisting of alternations of volcanic 

 ash, scoria, and lava. In the first eruption was observed a soft sand- 

 stone rock, 18 in. thick, which the author, from the occurrence in it of 

 leaves of toetoe {Arundo conspicua) or of raupo {Typlia latifolia), con- 

 siders to have been deposited in a freshwater lake which then occupied 

 the crater of Mt. Eden. The sandstone is overlain by a mud rock, 

 perforated by cylindrical holes, resembling the trunks and branches of 

 trees. The first eruptions probably followed each other at very short 

 intervals. R. E., Jun.

 In the discussion, Mr. Daintree stated that the explorations of 

 Messrs. Eorrest and Warburton have proved his prognostications con- 

 cerning the geological structure of the centre of Australia to be correct, 

 viz. that the Desert Sandstone at one time covered nearly, if not quite, 

 the whole of Australia, and that the Cretaceous series of W. and Central 

 Queensland extends to W. Australia, but is hidden over large areas by 

 Desert Sandstone. R. E., Jun.
