NOTES AND EXHIBITS. - 761 



Mr. W. S. Dun exhibited specimens of green carbonate of 

 copper from the Narrabeen Shales of Long Reef. Attention was 

 first drawn to these by Mr. Bensusan. Copper also occurs in 

 the native form as separate particles or associated with carbon- 

 ised plant remains. The carbonate originally occurred as native 

 copper. Native copper has been found at lower horizons of the 

 Narrabeen Shales in bores at Newington, Holt-Sutherland and 

 Heathcote, and also at Bulli (vide T. W. E. David, Austr. 

 Assoc. Adv. Sci., i., pp. 275-290).

 past year on the development of Marsupials, and including photo- 

 graphs of the early stages in the development of Dasyurus 

 viverrinus; and photographs and drawings illustrating the evolu- 

 tion of the external form and the condition of the foetal mem- 

 branes in Trichosurus vulpecula, Phascolomys mitchelli and
