4. " Meteoric Dusts, New South Wales," by Professor 



LlVERSIDGE, M.A., LL.D., F.R.S. 



The term meteoric dust is used because it is commonly 

 applied to the materials forming the subject of this paper; 

 it is not intended to state that the dusts are necessarily 

 of cosmic or extra terrestrial origin. The specimens 

 described and exhibited were from Moruya, (fell on Dec. 15 

 1880); from Uralla, (fell on Dec. 14th, 1882); from near 

 Broken Hill, (fell 1896); from Menindie (fell June 17th, 

 1899); and Pambula, (fell Oct. 5th, 1899). Dust from the 

 roof -beams and mud from a covered cistern at the Uni- 

 versity and from the roof of the Observatory, Sydney; all 

 three were collected in 1882. All the dusts are of a red- 

 dish colour except those from the University and Obser- 

 vatory, which are grey. The red dusts are mainly silicious 

 and argillaceous, and look as if they had come from dried 

 up water-holes, they contain a variety of organic and 

 mineral matters such as might be expected from such a 

 source, and in addition magnetite and metallic iron ; the 

 latter contains cobalt and nickel which seems to indicate 

 that the dusts contain some cosmic or extra-terrestrial 

 materials, part of which may have settled down and become 

 mingled with the undoubted superficial terrestrial deposits 

 and part may have been derived directly from the atmo-
