These muscles consist of ribbon-shaped bands which surround hollow fleshy tubes or cavities. We might compare them to India rubber rings on rolls of paper. As they are never attached to bony levers, they have no need of tendons. A, Muscular Fiber, showing Stripes, and Nuclei, b and c.
We may say, then, that the body consists of two tubes or cavities, separated by a bony wall, the dorsal or nervous tube, so called because it contains the central parts of the nervous system; and the visceral or ventral tube, as it contains the viscera, or general organs of the body, as the alimentary canal, the heart, the lungs, the sympathetic nervous system, and other organs.
We have it in claystone porphyry here, in minute round globules, no larger than turnip-seed, dotted thickly over the matrix; or crystallized round the walls of cavities, once filled with air or other elastic fluid; or it may appear in similar cavities as tufts of yellow asbestos, or as red, yellow, or green crystals, or in laminae so arranged as to appear like fossil wood.
He was a long lanky fellow with straight black locks flat against his sallow face, and dark eyes that smouldered in hollow cavities. He wore the King's colours, and broke a manchet of white bread with his mid-day repast.
The Creator places in all creatures the same five great essences in proportions that He thinks proper. Sound, the ears, and all cavities, these three, have Space for their producing cause. Taste, all watery or juicy substances, and the tongue, are said to be the properties of water. Form, the eye, and the digestive fire in the stomach, are said to partake of the nature of Light.
Nobody knows what the support of the tone is, but every vocal teacher knows how it feels. In the same way, no means is known for directly throwing the air in the nasal cavities into vibration. But the sensation in the front of the head, which indicates, presumably, the proper action of nasal resonance, is familiar to all teachers.
Most of these tones, if swelled to forte, would change from the head to the chest quality. It is probable that this change in quality is effected by a corresponding change in the vocal cord adjustment, as the conditions of the resonance cavities remain the same. But this cannot be determined by laryngoscopic observation.
Both were shrunken in shape, with their garments hanging loosely around their bodies, their eyes sunk in deep cavities, their cheek-bones prominently protruding, their breasts flat and fleshless, the ribs easily discernible, in short, they appeared more like a pair of skeletons, covered with shrivelled skin, than breathing, living men.
First, by muscular tension, muscular contraction, muscular effort the wrong way. Second, by vitalized energy, by expansion, and by added resonance of air in the inflated cavities the right way. Of course to produce expansion and inflation, true conditions of form and adjustment must prevail, through the movements given. Form has much to do with determining the quality and character of the tone.
The porous quartz, or that containing many cavities, is more frequently found auriferous and richly auriferous, than the very compact quartz. The best gold-bearing veins are usually yellowish or brownish in tinge, near the surface at least; but very rich specimens are found in white and bluish-white rock.
