Ordinary Meeting, June 2, 1903. 



Walter Rutt, O.E. (Honorary Treasurer), in the chair. 



Apology from President for non attendance. 



Exhibits. — A. H. C. Zietz, F. L.S. (Assistant-Director of the 

 Museum), exhibited a bunch of Eucalyptus seed cases, and a head 

 and some bones of the English garpike ( Belone vulgaris). A 

 peculiarity of the bones of this fish is that they are green. 

 Mr. Zietz also exhibited some very large barnacles (Balanus sp.) 

 from Thistle Island; a thread worm (Gordius sp.) from a cock- 

 roach ; the skull of a rabbit, with the incisors in both jaws grown 

 to abnormal length and curved ; and a specimen of fluorite 

 in a piece of crystalline limestone from Brighton. In reference 

 to the green bones of the garpike, Mr. Woolngugh remarked 

 that the colour may be caused by the presence of vivianite 

 in the bones, phosphate of iron having to some extent dis- 

 placed the phosphate of lime. This may take place either 

 under healthy conditions or the reverse. Mr. Zietz also 

 laid on the table a specimen of molybdenite from N.S. 

 Wales. Mr. Tepper stated that he had found deposits of the 

 same mineral near Reynella and Yorke Peninsula, and Mr. 

 Stirling Smeaton had found it in the gorge of Reedy Creek, 

 near Mannum. Mr. Woolngugh stated that molybdenite was 

 found in large blocks at Glen Innes, in N.S. Wales, and at 

 Moonta, in this State; that it was not of much value commercially, 

 but was used in the manufacture of steel. J. G. O. Tepper, 

 F.L.S., exhibited a case of Northern Territory butterflies, pre- 

 sented to the Museum by Mr. E. H. Hallack, and pointed out 

 how some of the specimens were devoid of scales on the anterior 

 wings, except where the dark markings occur, and that in some 

 instances the males, though smaller, were more beautiful than 

 the females. Mr. Tepper also showed a stone axe of European 

 origin from the collection of the late Mr. Henry Marshall, and a 

 flake with serrated edges — evidently used as a saw — from the 

 same collection. Referring to these, Mr. Woolngugh said that 

 the stone from which the axe was shaped might be diorite or 

 aphanite, whilst the flake mighb be of porcelanite or chert. Mr. 

 Tepper showed nests of the Thyridopterix huehneri from Mount 

 Lofty, which presented the appearance of ragged bags ; also a 

 rare fungus on daisy leaves Puccinea distmcta, McAlpine. 



W. G. Woolngugh, B.Sc, F.G.S., then gave a most interesting 

 and instructive account of the " Metamorphism of Rocks.*'
