Barratta Meteorites, No. 2. 

 Mr. Russell, b.a., c.m.g., p.r.s., Government Astronomer, 

 states that on May 23rd, 1889, he received from Mr. W. 

 Kilpatrick of Oornalla Station, two meteorites which he 

 had found on Barratta Station, 34 miles north of Deniliquin 

 and near the place where the large Barratta meteorite was 

 found about the year I860. 1 To distinguish these meteorites 

 from the one previously described, they will be referred to 

 as Barratta meteorites No. 2 and No. 3. 



Mr. Russell says 2 that one of the new meteorites (Bar- 

 ratta No. 2) is remarkably like the large one he has had 

 for so many years. He describes it as somewhat like the 

 former in colour both internally and externally, but it is not 

 so deeply fused on the surface. Its specific gravity is 3*706, 

 that of the old one being 3*387, and the weight 31^ tbs., 

 the other (Barratta No. 3) weighed 48 fbs. and its specific 

 gravity is 3*429; these data were determined by Mr. 

 Russell by weighing the whole mass of each meteorite. 



The three Barratta meteorites do not seem to have 

 weathered to any extent and are intact except for some 

 pieces which have been broken off by a hammer. All 

 three show large surfaces free from fused skin as if they 

 had been fractured after their flight had been either 

 wholly or in part arrested. 



Amongst the principal constituents easily recognised in 

 the photograph are chondri of enstatite, much fissured, 

 olivine, and particles of the nickel iron alloy. The metallic 

 portion of Barratta No. 2 in 34*5 grammes was found to be 

 6*13°/-; the amount varies in different parts as the metallic 

 particles are clearly seen to be unequally distributed.
