METEORITES, N.S.W. 355 



writing to Mr. Russell on February 8th, 1893, states that 

 the meteorite had been recently found about two miles 

 south of the one (Gilgoin meteorite No. 1) he had previously 

 sent Mr. Russell. Both were found on an alluvial plain 

 free from rocks or stones. Mr. Russell considered it prob- 

 able that as they were found so close together and are so 

 similar in appearance and specific gravity that they 

 originally formed parts of one meteorite, both travelled 

 through the atmosphere a sufficient distance, after split- 

 ting up, to acquire the usual fused skin, although this is 

 not so glossy as in some meteorites. 



Mr. Russell states 1 that like the previous one this 

 meteorite was also much weathered and cracked, some 

 pieces have fallen off and many parts of the surface are 

 ready to crumble away. The total weight of all the parts 

 amounted to 74 lbs. 4 ozs., and the specific gravity to 3*757. 

 The main mass is roughly doubly convex, 14 to 15 inches 

 in length and about 7 inches through at the thickest part. 

 A freshly fractured surface is dark grey in colour and shows 

 numerous bright white metallic particles. Its general 

 appearance is represented in Plate 14. Th e microphotograph 

 (Plate 12, fig. 13) shows the light coloured fissured enstatite 

 and the metallic particles (grey) in an opaque magma. 



The second Gilgoin meteorite has not yet been analysed. 

 Although the fractured surfaces and micro-sections of the 

 Gilgoin meteorites somewhat resemble those of the Barratta 

 meteorites they appear to be too far apart in composition 

 to have been portions of the same fall; the differences in 

 the places and the dates at which they were discovered 

 are not of much importance.
