 Art Gallery, the President (His Ex-

Apologies. 



The senior vice-president, the Hon. 

 Sir James Agnew, K.C.M.G., M.D., 

 etc., and the Hon. C. H. Grant, M.E.C., 

 sent an apology regretting their in- 

 ability to be present. 



New Members. 



Mr. F. G. Simpkinson-De Wessellow, 

 R.N., jrho, since the last session, had 

 presented a number of water colour 

 sketches to the Society, was unanimous- 

 ly elected an honorary member of the 

 Society. Messrs. Frank Allwork, 



L.S.A., of New Norfolk, and P. J. 

 MiiLeod, B.Sc, were eleotsd FeMows of 

 the' Society. 



Her Late Majesty. 



Sir John Dodds, who was received 

 with applause, said that this was the 

 first occasion this year of the Society's 

 meeting. They were all aware that 

 Her late Majesty was the patron of 

 their Society, and they were all honour- 

 ed in the person of that p&cron. It 

 was, therefore, fitting that on this oc- 

 casion they should record their sense 

 of the loss which the nation and this 

 Society had sustained by the death of 

 Queen Victoria. For more than 60 

 years Her late Majesty had exercised a 

 personal influence for good which had 

 made itself felt throughout the whole 

 of the Empire. There was no feeling 

 comparable in intensity Avith the feel- 

 ing which Her late Majesty had en- 

 gendered in the hearts of her subjects, 

 and it would be idle for him to attempt 

 in any way to describe the loss which 

 the nation had sustained, and he 

 thought it right to invite them to agree 

 in expressing their deep sorrow for the 

 loss of a sovereign, perhaps the greatest 

 one they had ever known in their his- 

 tory. Let the example of her noble 

 life abide with them as a people, and 

 stimulate them to greater efforts. (Ap- 

 plause.) 



Mr. Alex. Morton said an address to 

 the Duke of Cornwall and York had 

 been prepared on behalf of the Society. 



Mr. Osborne Greene suggested that 

 the use of the Society's rooms might be 

 extended for the presentation to be 

 made to Her late Majesty's grandson. 

 Sir John Dodds thought that the sug- 

 gestion might be conveniently referred 

 to the Council of the Society for con- 

 sideration, but pointed out that Go- 

 vernment House had been fixed as the 

 place for the presentation of addresses 

 to the Royal visitors, and he ventured 

 to think that that would be more ac- 

 ceptable. 



Papers. 



Sir John Dodds then said he had much 

 pleasure in introducing to the Society 

 Mr. Wm. Heyn, of the Timber Depart- 

 menit Admiralty — HarbO'-ur Goai'traiCft 

 Works, Dover, England. 



In the absence of the authors, the 

 secretary read the following papers. 

 (a) Description and analysis of a new 

 species of mineral, "Petterdite," a new 

 oxychloride of lead, by Mr. W. H. 

 Twelvetrees, F.G.S., Government Geo- 

 logist. The author said this apparent- 

 ly absolutely new chemical combination 

 occurs in attached crystal groups in a, 

 quartz gangue containing disseminated 

 pyrites, in the form of somewhat thin 

 hexagonal plates, which are usually 

 minute in size (about 5 millimetres in 

 diameter), but occasionally reach 9 min. 

 dia., and still more rarefy a larger size. 

 It was, says the writer, evidently rare, 

 and, so far as known, confined to the 

 locality mentioned. The specimen, of 

 which a slide was thrown on the 

 screen, was remarkably fine, con- 

 taining about 200 perfectly-formed im- 

 planted crystals. Mr. Twelvetrees said 

 the mineral was a very attractive speci- 

 men, and was easily distinguishable 

 from the more abundant sulphate and 

 carbonate of lead, and was occasionally 

 associated with fine groups of campylite. 

 He had great pleasure in dedicating it 

 to Mr. W. F. Petterd, of Launceston, 

 who had done so much in the work of 

 Tasmanian minerals. 



The next paper was by Mr. W. F. Pet- 

 terd, who gave a description of a me- 

 teorite from the Castray River, Tas-
