The Tawallah Valley meteorite. General description. The Microstructure
[No abstract is given for this work, it begins as follows] General Description. Little information is available about the finding of this meteorite. Mr. Heathcock, Constable-in-Charge of the Borroloola Police Station, Northern Territory, informed me in April, 1939, that it had been in the Police Station for eighteen months or more. It was found by Mr. Condon, presumably some time in 1937. The weight of the iron as received was 75.75 kg. (167 lb.). A small piece had been cut off, but its weight probably did not exceed 200 grammes. The main mass weighing 39.35 kg. (86 3/4 lb.) is in the collection of the Geological Survey, Department of the Interior, Canberra. A portion weighing 30.16 kg. 66 ½ lb.) and five pieces together weighing 1.67 kg. are in the collection of the Australian Museum, and a slice weighing 453 grammes is in the Museum of the Geology Department, the University of Melbourne.
