A meteoric stone found in 1931 by Mr. Bertram Thomas at Buwah (lat. 20° 3ʹ 10ʺ N., long. 51° 25ʹ E.) in the region of Suwahib in the Rub' al Khali, Arabia, has already been described in this Magazine. In 1932, Mr. H. St. J. B. Philby, travelling on a route some miles to the west of that followed by Mr. Bertram Thomas, picked up meteoric stones at three other places. Two of these are between 25 and 30 miles to the west of Buwah, and the third, Umm Tina, 3 miles north of Shanna, lies about 70 miles to the south.

Dr. Herbert Basedow of Adelaide generously presented in November 1931 for the British Museum collection of meteorites a pallasite which he had collected in Central Australia in 1924 while leading the Vice-Regal Expedition. During his extensive explorations in Central and Northern Australia it had remained unpacked for some years. He gives the locality as on the Burr Plains, NNE. of Bond Springs in the Alice Springs district ; lat. 23° 33′ S., long. 133° 52′ E. This is immediately north of the MacDonnell Ranges and about ten miles north of Alice Springs. The fragment was found lying on the surface and only partly buried in loose ferruginous sand. No doubt other pieces of this material remain to be found in the district.

Starting in December 1930, Mr. Bertram Thomas made the crossing of the Rub' al Khali, the desert region of Arabia lying between the mountains of the south coast and the Persian Gulf. Never before had this desert been crossed by any European, and probably rarely even by Arabs. The material collected on this expedition has been presented by Mr. Thomas for preservation in the British Museum.
