tion may be of interest : — The form is bounded by a series of 

 more or less concave and irregularly-shaped planes. The 

 surface is, for the most part, coated with a somewhat shining 

 and dark-brown oxide of iron. This meteorite consists of 

 metallic iron and contains a small proportion of nickel. It 

 weighs 3,2687 grm., or 7 lbs. 3i ozs. As originally found it 

 was a trifle heavier, a small piece having been broken off by the 

 finder ; and the long chisel mark to the right hand on the top 

 shows where an attempt was made to cut off a larger piece. 

 The locality and circumstances attending the discovery of the 

 meteorite are thus described by Mr. James Martlew : — " I 

 found the stone on the flat in a mallee scrub about half a mile 

 from the northern foot of the range, being distant four miles 

 south of Tardea Station. It was about 15 inches under the 

 surface, and was surrounded for about three feet by limestone 

 broken into small pieces. All round this there was from four 

 to eight inches of soil covering the limestone." 



Magnetite. 

 This species occurs near Mount Jagged, and Burr states that 

 the crystallised and massive varieties are of very general occur- 

 rence from Cape Jervis to Black Rock Hill. Tate reports it in 

 the vicinity of the Peake, Central Australia, and in the Hun- 

 dred of Cunningham. The following analysis of a sample of

HAEMATITE. 



Var. Micaceous Hcematite occurs at numerous localities in this 

 province, among which may be mentioned the following : — 

 Angaston, Port Lincoln, near Inglewood, at the Yudanamutana 

 Copper Mine and the Paramatta Mine, Yorke Peninsula. 

 It occurs in the quartz veins running through the metamorphic 

 rocks in the neighbourhood of the Peake and at Teunant 

 Creek, Central Australia (Tate). Also in druses in close 

 proximity to the copper deposits at the Blinman Mine (L^lrich)
