About one sixth of the native population of the interior, and a smaller proportion of those living on the coast, suffer from a kind of ringworm called kurap, which also prevails almost universally among the Sakai and Semang, the aboriginal hill tribes of the Malayan Peninsula.
Used more accurately, it denotes the tribe which invaded India 130-140 B.C. They are the Sacae and Sakai of classical authors and the Se of the Chinese, which may represent an original Sek or Siik.

Broadly speaking, all the brown races which inhabit the portion of Asia south of Siam and Indo-China, and the islands from the Philippines to Java, and from Sumatra to Timor, may be described as belonging to the Malayan family, if the aboriginal tribes, such as the Sakai and Semang in the Malay Peninsula, the Bataks in Sumatra, and the Muruts in Borneo, be excepted.
