The decorative art of the aborigines of the Malay Peninsula has already been described in some detail by various writers. The best known and most important of these contributions to our knowledge of the subject are those of A. Grünwedel in the Zeitschrift für Ethnohgie, Bd. xxvi, p. 141 (under the title “Die Zaubermuster der Orang-Utan”) and Bd. xxv, p. 71. In Bd. xxxi, p. 137, of the same periodical Th. Preuss enlarged on the same theme. W. W. Skeat also devoted many pages in vol. i of his Pagan Races of the Malay Peninsula to this subject, and J. H. N. Evans has recently expressed his views on it in the Journal of the Federated Malay States Museums, vol. xii, part i.
