It has hitherto been considered as an obvious truth, and admitted without examination that, wherever they are found upon the numerous islands forming this archipelago, they or their ancestors must have migrated from the country named by Europeans (and by them alone) the Malayan peninsula or peninsula of Malacca, of which the indigenous and proper inhabitants were understood to be Malays; and accordingly in the former editions of this work I spoke of the natives of Menangkabau as having acquired their religion, language, manners, and other national characteristics from the settling among them of genuine Malays from the neighbouring continent.  It will however appear from the authorities I shall produce, amounting as nearly to positive evidence as the nature of the subject will admit, that the present possessors of the coasts of the peninsula were on the contrary in the first instance adventurers from Sumatra, who in the twelfth century formed an establishment there, and that the indigenous inhabitants, gradually driven by them to the woods and mountains, so far from being the stock from whence the Malays were propagated, are an entirely different race of men, nearly approaching in their physical character to the negroes of Africa.

MIGRATION FROM SUMATRA.

The evidences of this migration from Sumatra are chiefly found in two Malayan books well known, by character at least, to those who are conversant with the written language, the one named Taju assalatin or Makuta segala raja-raja, The Crown of all Kings, and the other, more immediately to the purpose, Sulalat assalatin or Penurun-an segala raja-raja, The Descent of all (Malayan) Kings.  Of these it has not been my good fortune to obtain copies, but the contents, so far as they apply to the present subject, have been fully detailed by two eminent Dutch writers to whom the literature of this part of the East was familiar.  Petrus van der Worm first communicated the knowledge of these historical treatises in his learned Introduction to the Malayan Vocabulary of Gueynier, printed at Batavia in the year 1677; and extracts to the same effect were afterwards given by Valentyn in Volume 5 pages 316 to 320 of his elaborate work, published at Amsterdam in 1726.  The books are likewise mentioned in a list of Malayan Authors by G.H.  Werndly, at the end of his Maleische Spraak-kunst, and by the ingenious Dr. Leyden in his Paper on the Languages and Literature of the Indo-Chinese Nations, recently published in Volume 10 of the Asiatic Researches.  The substance of the information conveyed by them is as follows; and I trust it will not be thought that the mixture of a portion of mythological fable in accounts of this nature invalidates what might otherwise have credit as historical fact.  The utmost indeed we can pretend to ascertain is what the natives themselves believe to have been their ancient history; and it is proper to remark that in the present question there can be no suspicion of bias from national vanity, as we have reason to presume that the authors of these books were not Sumatrans.
