alkali removes phosphorus, the results are only of value 

 for the proportions of iron, nickel, and cobalt. 



Plate 8 is from a photograph of Barratta No. 2. 



Plate 10, fig. 9, shows the fractured surface of the 

 meteorite Baratta No. 2, the light coloured oval and round 

 spots are enstatite chondri and some of the bright specks 

 are metallic. The metallic portions are shown better in 

 the polished surface of the meteorite, see fig. 10 on the same 

 plate, in the form of light coloured irregular markings, 

 some are curved and a few are circular and are apparently 

 sections of investing coats of metallic matter, if the non- 

 metallic nuclei could be removed we should apparently 

 have hollow spherules of the nickel-iron alloy. 



Plate 11, fig. 11, is a photograph of a section enlarged 12 

 diameters, of Barratta No. 2, which shows the fissured 

 structure of the enstatite chondri, the opaque magma, 

 and some of the metallic grains. 



Barratta Meteorite No. 3. 

 Barratta meteorite No. 3 has not been analysed ; it 

 evidently belongs to the same original mass as Nos. 1 and 2. 

 Plate 9 represents Barratta No. 3. 



Plate 11, fig. 12, shows portions of two of the enstatite 

 chondri (enlarged 16 diameters) between them are to be 

 seen thin pieces of the metallic alloy, the two lower ones 

 roughly triangular in outline — the striae on them are due 

 to the polishing material. 



Gilgoin Meteorite, No. 1. 

 This meteorite was given to Mr. Russell, c.m.g., f.r.s., 

 by Mr. J. A. Yeomans of Gilgoin Station, where it was 

 found in 1889. Gilgoin is 40 miles E.S.E. of Brewarrina, 

 which is 516 miles N.W. of Sydney and 75 miles E. from 

 Bourke, the latter town is 503 miles from Sydney and in
