In his survey Hertz (=33=, p. 66) calls attention to the widespread custom of temporary burial throughout Indonesia, but, instead of recognising that such procedures have come into vogue as a degradation of the full rites incidental to mummification, he regards it as part of a widespread “notion que les derniers rites funéraires ne peuvent pas être célébrés de suite après la mort, mais seulement à l’expiration d’une période plus on moins longue” (p. 66); and regards mummification simply as a specialised form of this rite which is almost universal (p. 67):—“il paraît légitime de considérer la momification comme un cas particulier et dérivé de la sépulture provisoire.” (p. 69). This is a remarkable inversion of the true explanation. For the enormous mass of evidence which is now available makes it quite certain that the practice of temporary burial was adopted only when failure (or the risk of failure) to preserve the body compelled less cultured people to desist from the complete process. I am in full agreement with Hertz when he says:—“L’homologie entre la préservation artificielle du cadavre et la simple exposition temporaire paraîtra moins difficile à admettre si l’on tient compte du fait qui sera mis en lumière plus bas: les ossements secs, résidu de la décomposition, constituent pour le mort un corps incorruptible, absolument comme la momie.” (p. 69). But does not this entirely bear out my contention? It is quite inconceivable that the practice of mummification could have been derived from the custom of preparing the skeleton; but the reverse is quite a natural transition, for even in the hands of skilled embalmers (see especially =39=), not to mention untutored savage peoples, the measures taken for preserving the body may fail and the skeleton alone may be spared. If this contention be conceded, the demonstration given by Hertz of the remarkable geographical distribution of customs of temporary burial affords a most valuable confirmation of the general scheme of the present communication. “Au point de vue où, nous sommes placés, il y a homologie rigoureuse entre l’exposition du cadavre sur les branches d’un arbre, telle que la pratiquent les tribus du centre de l’Australie, ou à l’intèrieur de la maison des vivants, comme cela se rencontre chez certains Papous et chez quelques peuples Bantous, ou sur une plateforme élevée à dessein, ainsi que le font en général les Polynésiens et de nombreuses tribus indiennes de l’Amérique du Nord, ou enfin l’enterrement provisoire, observé en particulier par la plupart des Indiens de l’Amérique du Sud” (p. 67). There can be no doubt whatever of the justice of this “homology,” for in every one of the areas mentioned these customs exist side by side with the practice of mummification; and in many cases there is definite evidence to show that the other methods of treatment have been derived from it by a process of degradation.
