According to Father Tachard, the Siamese are exceedingly alert, and have among them tumblers, &c. not less expert and skilful than those in Europe. He says, that the custom they have of blackening the teeth, proceeds from an idea that it is not becoming in man to have teeth white like the brute creation; that it is for this reason they begrime them with black varnish, and then abstain from meat for several days, that it may thoroughly adhere.
The inhabitants of the kingdom of Pegu and Aracan are more black, yet bear a strong resemblance both to the Siamese and the Chinese. Those of Aracan put great value upon a forehead large and flat, and to render them so, they apply a plate of lead to the forehead of their children the minute they are born. Their nostrils are large, their eyes are small and lively, and their ears are of such length as to hang over their shoulders. They feed without disgust on mice, rats, serpents, and fish, however corrupted. Their women are tolerably fair, and their ears are as long as those of the men. The people of Achen, who are situated further north than those of Aracan, have also flat visages, and an olive-coloured skin; they allow their boys to go quite naked, and their girls have only a slight plate of silver to conceal what Nature dictates.
None of these nations differ much from the Chinese, and all resemble the Tartars in the smallness of their eyes, the largeness of their visage, and the olive colour of their skin. In proceeding southward the features begin to change more sensibly. The inhabitants of Malacca, and of the island of Sumatra, are black, diminutive, lively, and well proportioned. Though naked from the middle upward, a little kind of scarf excepted, which they wear sometimes over the right and sometimes over the left shoulder, their aspect is fierce. They are naturally brave, and even formidable when they have swallowed a certain quantity of opium, which intoxicates them with a kind of fury.
According to Dampier, the inhabitants of Sumatra and Malacca are of the same race; they speak nearly the same language, and they have the same bold and haughty disposition. They are of a middling stature, their visage long, their eyes black, their noses of a moderate size, their lips thin, and their teeth are blackened.
