PROCEEDINGS, JUNE. 



XV 



place since it was deposited on its sandy bed, as well as by the existence 

 of the Yarra River, of a similar change at a similar period at the site of 

 the Geilston Bay freshwater limestone at Richmond, in Tasmania. A 

 quarter of a century ago I published a popular description, under the 

 title of "A Story of a Stone," of the great geological changes which 

 had taken place since the traverting beds had beep laid down by the 

 eruption of basalt, and the subsequent formation of the River Derwent. 

 The relation that the Yarra River bears to the fossil tree, its sand bed, 

 and superimposed basaltic covering, is precisely the same as that ^which 

 the Derwent River bears to the f ossiferous travertine deposits." Mr. 

 Barnard added that similar specimens had been presented to the 

 Tasmanian Museum by his son, Dr. Barnard, while in New South Wales. 



Mr. Morton expressed regret at the absence of Mr. R. M. Johnston, 

 owing to indisposition, as that gentleman was well acquainted with the 

 subject, having largely referred to it in his " Geology of Tasmania." 



Mr. C. H. Grant said that the grain of the wood and general 

 appearance of the specimens showed that the dioritic formation that 

 poured out upon the trunk of the tree was at a lower temperature than 

 Was generally supposed. 



SPECIMENS. 



Mr. T. B. Moore exhibited specimens of Eucalyptus, a variety of 

 Risdoni, and a garnet stone from Collingwood Valley, West Coast. 



Mr. Morton exhibited two parrots, presented by Mr. F. Back, 

 General Manager of the Government Railways. They are the Kea (Nestor 

 notabilis), natives of New Zealand, and very destructive to sheep. 



Mr. Curzon Almost exhibited a specimen of black marble, taken 

 from the mouth of the Gordon Kiver, West Coast. Samples had been 

 sent to London, and a company formed to work the same. 



Mr. Morton submitted specimens of ferns connected with limestone 

 formations taken from the Chudleigh Caves. 



On the motion of His Excellency, votes of thanks were passed to the 

 gentlemen who contributed papers. 



The proceedings terminated.
