CHAP. XL AND NEGATION. 275 shaking the head in negation was never used, and was not even understood by them. With the Esquimaux24 a nod means yes and a wink no. The New Zealanders " elevate the head and chin in place of nodding acquies- cence." 25 With the Hindoos Mr. BL Erskine concludes from inquiries made from experienced Europeans, and from native gentlemen, that the signs of affirmation and ne- gation vary—a nod and a lateral shake being sometimes used as we do; but a negative is more commonly ex- pressed by the head being thrown suddenly backwards and a little to one side, with a cluck of the tongue. What the meaning may be of this cluck of the tongue, which has been observed with various people, I cannot imagine. A native gentleman stated that affirmation is frequently shown by the head being thrown to the left. I 'asked Mr. Scott to attend particularly to this point, and, after repeated observations, he believes that a vertical nod is not commonly used by the natives in affirmation, but that the head is first thrown backwards either to the left or right, and then jerked obliquely forwards only once. This movement would perhaps have been de- scribed by a less careful observer as a lateral shake. He also states that in negation the head is usually held nearly upright, and shaken several times. . Mr. Bridges informs me that the Fuegians nod their heads vertically in affirmation, and shake them laterally in denial. With the wild Indians of North America, according to Mr. Washington Matthews, nodding and shaking the head have been learnt from Europeans, and are not naturally employed. They express affirmation "•by describing with the hand (all the fingers except the 34 Dr. King, Edinburgh Phil. Journal, 1845, p. 313. 25 Tylor, * Early History of Mankind,' 2nd edit. 1870, p. 53.
