There are many isolated data in the Malay Archipelago that still await scientific explanation. Dr. G. de Hevesy claimed to have discovered a kinship between the script of Easter Island and that of Harappa and Mohenjo-Daro (Bulletin de la Socéité préhistorique Française, 1933, Nos. 7–8; The Script of Harappa and Mohenjodaro, E. R. Hunter, London, 1934); Sir Elliot Smith detected Egyptian influence in the banners of Alur Islands (Human History, 1930, p. 339); Dr. Paul Rivet discovered a Sumerian element in Oceanian languages (Proceedings of the Fourth Pacific Science Congress, Batavia, 1930, vol. iii, pp. 519–527). And to these unsolved problems may be added the art motif of a bird perched on an animal.
