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.
With chemical analyses by M. H. HeyY, B.A., B.Sc.
A preliminary account was given in an appendix to Mr. Thomas's paper, ‘A camel journey across the Rub' al Khali’, in the Geogr. Journ. London, 1931, vol. 78, 13. 236. There the specific gravity is given incorrectly.

page 47 note 1 E. de Oliveira lists a meteorite [N. 2640] from 'Arabia' in the collection of the Museu Nacional at Rio de Janeiro, Brazil, but he gives no description. (Ann. Acad. Brasileira Sei., 1931, vol. 3, p. 52, and Min. Abstr., 1932, vol. 5, p. 14). This is probably a piece of the Hedjaz stone. A pseudo-meteorite from 'Yafaee Mountains, Arabia' was included in the British Museum lists of 1886 (p. 69) to 1896 (p. 86).
