There is another little gesture, expressive of astonishment of which I can offer no explanation; namely, the hand being placed over the mouth or on some part of the head. This has been observed with so many races of man, that it must have some natural origin. A wild Australian was taken into a large room full of official papers, which surprised him greatly, and he cried out, _cluck, cluck, cluck_, putting the back of his hand towards his lips. Mrs. Barber says that the Kafirs and Fingoes express astonishment by a serious look and by placing the right hand upon the mouth, uttering the word _mawo_, which means ‘wonderful.’ The Bushmen are said[1213] to put their right hands to their necks, bending their heads backwards. Mr. Winwood Reade has observed that the negroes on the West Coast of Africa, when surprised, clap their hands to their mouths, saying at the same time, “My mouth cleaves to me,” i. e. to my hands; and he has heard that this is their usual gesture on such occasions. Captain Speedy informs me that the Abyssinians place their right hand to the forehead, with the palm outside. Lastly, Mr. Washington Matthews states that the conventional sign of astonishment with the wild tribes of the western parts of the United States “is made by placing the half-closed hand over the mouth; in doing this, the head is often bent forwards, and words or low groans are sometimes uttered.” Catlin[1214] makes the same remark about the hand being pressed over the mouth by the Mandans and other Indian tribes. _Admiration_.—Little need be said on this head. Admiration apparently consists of surprise associated with some pleasure and a sense of approval. When vividly felt, the eyes are opened and the eyebrows raised; the eyes become bright, instead of remaining blank, as under simple astonishment; and the mouth, instead of gaping open, expands into a smile. _Fear, Terror_.—The word ‘fear’ seems to be derived from what is sudden and dangerous;[1215] and that of terror from the trembling of the vocal organs and body. I use the word ‘terror’ for extreme fear; but some writers think it ought to be confined to cases in which the imagination is more particularly concerned. Fear is often preceded by astonishment, and is so far akin to it, that both lead to the senses of sight and hearing being instantly aroused. In both cases the eyes and mouth are widely opened, and the eyebrows raised. The frightened man at first stands like a statue motionless and breathless, or crouches down as if instinctively to escape observation.
