140 H. A. Ward — Four New Australian Meteorites. 



Mooranoppin. 



This octahedral iron was found in or before 1893 by an 

 aboriginal on the sand-plains near Mooranoppin, 160 miles east 

 of York, Western Australia. Its general shape was that of an 

 oblong bar 10 cm in length, 8 cm wide and 4 cm thick. Its weight 

 was 2J lbs. The original crust is shown on exterior surface of 

 a brownish black color. 



The blades of kamasite are so broad that the Widmanstat- 

 ten figures are not prominently clear on an etched surface. 

 The sections are penetrated by numerous fissures, the largest 

 of which are l mm wide and 3 mm long. These fissures are filled 

 with a black graphitic mineral. A nodule of the same mate- 

 rial H cm in diameter occurs at one end of the section and is 

 surrounded by a band of troilite. A few small nodules of 

 troilite, ranging from 1 to 3 mm in diameter, occur also sparingly 

 in the section. 



This entire mass was obtained by me from the Perth Museum 

 in 1896. I have since cut it into slices.
