It is not my intention to discuss the evidence for the coming of the “heliolithic” culture to Indonesia, for the complex problems of this region have been analysed and interpreted in a masterly fashion by W. J. Perry in a book which is shortly to be published. The form which my present communication has assumed is largely the outcome of the reading of Perry’s manuscript and of discussions with him of the new lines of investigation which it suggested; and I am satisfied to leave this region for him to elucidate in detail. It will suffice to say here that the traditions of the inhabitants of the various islands of Malaysia, no less than their heterogeneous customs and beliefs, provided him with very precise evidence in demonstration of the complex constitution of the “heliolithic” culture, and of the fact that it was brought to the islands by an immigration from the west. There is less need for me to analyse the vast literature relating to the burial practices in the islands of the Malay Archipelago since this useful service has already been accomplished by Hertz (=33=). Although I dissent from the main contention in his interpretation of the facts, his accurate record is none the less valuable on that account—perhaps indeed it is more useful, as it certainly cannot be accused of bias in favour of the views I am expounding. A great variety of burial customs, in most respects closely analogous to the practices of the Naga tribes of India, is found in Indonesia;—exposing the dead on trees or platforms, burial in hollow trees, smoking and other methods of preservation, temporary burial, and cremation. Apart from the definite evidence of preservation of the dead found in scattered islands from one end of the Archipelago to the other, there are much more generally diffused practices which are unquestionably derived from the former custom of mummification. In the account of mummification as practised in the more savage African tribes, it was seen that the practice was restricted in most cases to the bodies of kings; and even then the failure to preserve the body in a permanent manner compelled these peoples to modify the Egyptian methods. Realising that the corpse, even when preserved as efficiently as they were able to perform the work of embalming, would undergo a process of disintegration within a few months, it became the practice to rescue the skull, to which special importance was attached (for the definite reasons explained by the early Egyptian evidence).
