GILGOIN STATION NO. 1, NEAR BREWARRINA, NEW SOUTH WALES. No. 288. 



Stone, Ck. Weight, 290 grams. Fragment with polished surface 

 and crust. Date of fall unknown. Found 1889. Weight of original 

 mass about 30^ kilograms, or 67^ pounds. A compact chondritic 

 stone composed essentially of olivines and enstatites with metallic 

 iron and iron sulphide. The most striking feature is the abundance 

 of small, wavy, nearly parallel fracture lines, which may have been 

 produced by impact with the earth, or by shearing stresses in the 

 mass itself. Analysis by A. Liversidge yielded :
