our object being to show how the _resonator_, which, in this case, is the body of the violin, intensifies the tone of the string, and affects its quality. Illustrations exemplifying the same thing might be multiplied to any extent, but the one I have just given will suffice. As with the string, so with the vocal ligaments. Cut a larynx out of a dead body, put it in proper position on the top of a bellows, and force the air through it, and you will produce tone, but faint and poor tone. Now add a resonator to the larynx, and the tone of the vocal ligaments will be intensified, and its quality altered according to the kind of resonator you make use of. It is clear, therefore, that the human voice does not only depend upon the vibrations of the vocal ligaments, and the corresponding vibrations of the air passing between them, but also upon the resonator as defined on p. 9. According to the natural formation of our resonator, and according to the infinite variety of shapes which every one has it in his power to give to it, our voices will be, always supposing the conditions of the vocal ligaments to be the same, either full, round, sonorous, and _beautiful_, or they will be poor, cutting, muffled, guttural, nasal, and _ugly_. As we have, or may easily acquire, absolute command over the resonator, or, at least, over the greatest part of it, it is a comfort to know that so very much depends upon it, and I trust my readers will now, with some amount of pleasure, look with me at this part of the vocal apparatus. The 1st and 2nd divisions of the resonator--namely, the pockets of the larynx and the tube above the pocket ligaments--have been fully described on pp. 52, 53, and no more need be said on the subject here. The upper part of the throat, called in scientific works the "Pharynx" (pl. I, P), is a cavity, the largest part of which may be seen through the arch at the back of the open mouth. Its hinder wall is formed by the spinal column, and it extends upwards as far as the Eustachian tubes (pl. I, E) which communicate with the middle part of the ear. Here it joins-- The =Cavities of the Nose= (pl. I, N), which have for their base the hard and soft palate (pl. I, H and S), and which are divided by a bone partition. The only part of the =Mouth= which requires a particular description is the soft palate. This is a movable partition by means of which either the mouth or the nose can be completely separated from t
