XIV PROCEEDINGS, AUGUST. 



Baron Mueller also acknowledged indebtedness to Mr. Moore for 

 providing him with specimens of the Panax Gunnii, a rare shrub, found 

 in deep shady gorges at Mount Lyell on the Canyon River, the 

 Franklin River, and on a tributary of the Pieman River. From the 

 highlands of Mount Read and Mount Tyndall, Mr. Moore sent speci- 

 mens of the Pentachondra verticillata, a species of Styphelia, which 

 until now was only known from Dr. Miliigan's collection. 



MOUNT LYELL. 



The Secretary, in the absence of the author, read notes on the Mount 

 Lyell district by Mr. F. Danvers-Power, F.G.S., being a rejoinder to 

 criticisms by members of the Society on the paper recently written by him 

 on that subject. The writer expressed surprise that his critics credited 

 him with being the author of new theories. It was possible that hewasthe 

 first to apply the views expressed in his paper to Tasmanian geology, 

 but he did not pretend to be the originator ot what Mr. Stephens termed 

 the " water pressure and wave theory," or of the anti-true-fissure-lode 

 theory, although he was prepared to uphold them until disproved, or 

 more suitable substitutes were brought forward, His paper was in- 

 tended to give but a sketch of the geology of the Mount Lyell district. 

 He was aware from Tasmanian literature, as also by personal con- 

 versation, that his views were in opposition to those generally accepted 

 in the island, but by bringing the results of modern research to bear on 

 local conditions, he had hoped to direct thought out of^the groove into 

 which it had fallen. Of course he did not expect to win those who had 

 strong views on the subject over to his side at once, but he did expect 

 them either to give valid arguments for their side of the question, or 

 to prove his incorrect, especially when those sentiments were due to 

 misconceptions on their part. He then dealt at length with the points on 

 which his critics differed from him— (1) the main cause of mountain 

 ranges ; (2) the nature of most so-called true fissure lodes. 



Discussion on Mr. Power's paper was postponed to a future meeting. 



This concluded the meeting.
