in the history of our race. It seems, however, that in the daily intercourse of the lower races, gesture holds a much more important place than we are accustomed to see it fill, a position even encroaching on that which articulate speech holds among ourselves. Mr. Bonwick confirms by his experience Dr. Milligan's account of the Tasmanians as using signs to eke out the meaning of monosyllabic expressions, and to give force, precision, and character to vocal sounds.' Captain Wilson remarks on the use of gesticulation in modifying words in the Chinook Jargon. There is confirmation to Spix and Martius' description of low Brazilian tribes completing by signs the meaning of their scanty sentences, thus making the words 'wood-go' serve to say 'I will go into the wood,' by pointing the mouth like a snout in the direction meant. The Rev. J. L. Wilson, describing the Grebo language of West Africa, remarks that they have personal pronouns, but seldom use them in conversation, leaving it to gesture to determine whether a verb is to be taken in the first or second person; thus the words 'ni ne' will mean ‘I do it,' or 'you do it,' according to the significant gestures of the speaker.1 Beside such instances, it will hereafter be noticed that the lower races, in counting, habitually use gesture-language for a purpose to which higher races apply word-language. To this prominent condition of gesture as a means of expression among rude tribes, and to the development of pantomime in public show and private intercourse among such peoples as the Neapolitans of our own day, the most extreme contrast may be found in England, where, whether for good or ill, suggestive pantomime is now reduced to so small a compass in social talk, and even in public oratory.

Changes of the bodily attitude, corresponding in their fine gradations with changes of the feelings, comprise condi

tions of the surface of the body, postures of the limbs, and also especially those expressive attitudes of the face to which our attention is particularly directed when we notice one another. The visible expression of the features is a symptom which displays the speaker's state of mind, his feelings of pleasure or disgust, of pride or humility, of faith or doubt, and so forth. Not that there is between the emotion and its bodily expression any originally intentional connexion. It is merely that a certain action of our physical machinery shows symptoms which we have learnt by experience to refer to a mental cause, as we judge by seeing a man sweat or limp that he is hot or footsore. Blushing is caused by certain emotions, and among Europeans it is a visible expression or symptom of them; not so among South American Indians, whose blushes, as Mr. David Forbes points out, may be detected by the hand or a thermometer, but being concealed by the dark skin cannot serve as a visible sign of feeling. By turning these natural processes to account, men contrive to a certain extent to put on particular physical expressions, frowning or smiling for instance, in order to simulate the emotions which would naturally produce such expressions, or merely to convey the thought of such emotions to others. Now it is well known to every one that physical expression by feature, &c., forming a part of the universal gesture-language, thus serves as an important adjunct to spoken language. It is not so obvious, but on examination will prove to be true, that such expression by feature itself acts as a formative power in vocal language. Expression of countenance has an action beyond that of mere visible gesture. The bodily attitude brought on by a particular state of mind affects the position of the organs of speech, both the internal larynx, &c., and the external features whose change can be watched by the mere looker-on. Even though the expression of the speaker's face may not be seen by the hearer, the effect of the whole bodily attitude of

which it forms part is not thereby done away with. For on the position thus taken by the various organs concerned in speech, depends what I have here called 'emotional tone,' whereby the voice carries direct expression of the speaker's feeling.

The ascertaining of the precise physical mode in which certain attitudes of the internal and external face come to correspond to certain moods of mind, is a physiological problem as yet little understood; but the fact that particular expressions of face are accompanied by corresponding and dependent expressions of emotional tone, only requires an observer or a looking-glass to prove it. The laugh made with a solemn, contemptuous, or sarcastic face, is quite different from that which comes from a joyous one; the ah! oh! ho! hey! and so on, change their modulations to match the expression of countenance. The effect of the emotional tone does not even require fitness in the meaning of the spoken words, for nonsense or an unknown tongue may be made to convey, when spoken with expressive intonation, the feelings which are displayed upon the speaker's face. This expression may even be recognized in the dark by noticing the tone it gives forth, while the forced character given by the attempt to bring out a sound not matching even the outward play of the features can hardly be hidden by the most expert ventriloquist, and in such forcing, the sound perceptibly drags the face into the attitude that fits with it. The nature of communication by emotional tone seems to me to be somewhat on this wise. It does not appear that particular tones at all belong directly and of themselves to particular emotions, but that their action depends on the vocal organs of the speaker and hearer. Other animals, having vocal organs different from man's, have accordingly, as we know, a different code of emotional tones. An alteration in man's vocal organs would bring a corresponding alteration in the effect of tone in expressing feeling; the tone which to us expresses surprise or anger might come to express pleasure, and so forth. As it is, children

learn by early experience that such and such a tone indicates such and such an emotion, and this they make out partly by finding themselves uttering such tones when their feelings have brought their faces to the appropriate attitudes, and partly by observing the expression of voice in others. At three or four years old they are to be seen in the act of acquiring this knowledge, turning round to look at the speaker's face and gesture to make sure of the meaning of the tone. But in later years this knowledge becomes so familiar that it is supposed to have been intuitive. Then, when men talk together, the hearer receives from each emotional tone an indication, a signal, of the speaker's attitude of body, and through this of his state of mind. These he can recognize, and even reproduce in himself, as the operator at one end of a telegraphic wire can follow, by noticing his needles, the action of his colleague at the other. In watching the process which thus enables one man to take a copy of another's emotions through their physical effects on his vocal tone, we may admire the perfection with which a means so simple answers an end so complex, and apparently so remote.

By eliminating from speech all effects of gesture, of expression of face, and of emotional tone, we go far toward reducing it to that system of conventional articulate sounds which the grammarian and the comparative philologist habitually consider as language. These articulate sounds are capable of being roughly set down in signs standing for vowels and consonants, with the aid of accents and other significant marks; and they may then again be read aloud from these written signs, by any one who has learnt to give its proper sound to each letter.

What vowels are, is a matter which has been for some years well understood.1 They are compound musical tones such as, in the vox humana stop of the organ, are sounded

1 See Helmholtz, 'Tonempfindungen,' 2nd ed. p. 163; McKendrick, Text Book of Physiology, p. 681, &c., 720, &c.; Max Müller, 'Lectures,' 2nd series, p. 95, &c.

by reeds (vibrating tongues) fitted to organ-pipes of particular construction. The manner of formation of vowels by the voice is shortly this. There are situated in the larynx a pair of vibrating membranes called the vocal chords, which may be rudely imitated by stretching a piece of sheet india-rubber over the open end of a tube, so as to form two half-covers to it, 'like the parchment of a drum split across the middle;' when the tube is blown through, the indiarubber flaps will vibrate as the vocal chords do in the larynx, and give out a sound. In the human voice, the musical effect of the vibrating chords is increased by the cavity of the mouth, which acts as a resonator or sounding-box, and which also, by its shape at any moment, modifies the musical 'quality' or 'timbre' of the sound produced. This, not the less felt because its effects are not registered in musical notation, depends on the harmonic overtones accompanying the fundamental tone which alone musical notation takes account of. It makes the difference between the same note on two instruments, flute and piano for instance, while some instruments, as the violin, can give to one note a wide variation of quality. To such quality the formation of vowels is due. This is perfectly shown by the common Jew's harp, which when struck can be made to utter the vowels a, e, i, o, u, &c., by simply putting the mouth in the proper position for speaking these vowels. In this experiment the player's voice emits no sound, but the vibrating tongue of the Jew's harp placed in front of the mouth acts as a substitute for the vocal chords, and the vowelsounds are produced by the various positions of the cavity of the mouth, modifying the quality of the note, by bringing out with different degrees of strength the series of harmonic tones of which it is composed. As to musical theory, emotional tone and vowel-tone are connected. In fact, an emotional tone may be defined as a vowel, whose particular musical quality is that produced by the human vocal organs, when adjusted to a particular state of feeling.
