Inasmuch as the vocal cords are subject to the same laws of vibration, the lesson drawn from the string and the bit of paper applies to them, the node taking the place of the paper. The string is single, and there is no attrition. If there were two strings, the bit of paper might be caught and twisted in the miniature whirlwind of opposing vibrations.
The periosteal gumma appears as a smooth, circumscribed swelling which is soft and elastic in the centre and firm at the margins, and shades off into the surrounding bone. The gumma may be completely absorbed or it may give place to a hard node. In some cases the gumma softens in the centre, the skin becomes adherent, thin, and red, and finally gives way.
No longer in clouds, but in closed rings, he supposed meteoric matter to revolve round the sun. Thus the mere circumstance of intersection by a meteoric of the terrestrial orbit, without any coincidence of period, would account for the earth meeting some members of the system at each annual passage through the "node" or point of intersection.
I work at the part of the belly which I call the centre, as it is the place where the bridge stands and answers to central node, consequently the middle of the whole construction and of the mass of air: I scrape and level here until I get a fraction, a hair or two less than one-eighth of an inch thick.
"That these are really stems, and not roots, is evident from the way in which they grow; from their consisting of a succession of joints; and from the leaves which they bear on each node, in the form of small scales, just like the lowest ones on the upright stem next the ground.
The cord loses its elasticity. It refuses to respond. It will neither act nor will it consent to be acted upon. It is in a state of collapse, and the voice for singing purposes has gone, never to return. Let me illustrate what rest will do for a node. A singer came to me with a node of three months' standing, on the left cord.
The stem, as the scholars have already learned, is the axis of the plant. The leaves are produced at certain definite points called nodes, and the portions of stem between these points are internodes. The internode, node, and leaf make a single plant-part, and the plant is made up of a succession of such parts. The stem, as well as the root and leaves, may bear plant-hairs.
Third the pitch, high or low, which is controlled by the distance from crest to crest of the sound-waves or, as we say, from node to node of the vibrations. To the most sensitive human ear, the highest limit of audibleness is reached by sound-waves estimated at twenty-eight-hundredths of an inch from node to node equal to 48,000 vibrations per second.
The extreme of lowness to which our sense of hearing is susceptible, has been placed at 75 feet from node to node or 15 vibrations per second. This total range of audibleness covers 12 octaves; running, of course, far above and far below the domain of music.
A long snout, with teeth and nostrils and accompanied by a pair of knobs for eyes, embellishes the right side as seen in the cut ears appear at the front and back, and a circular node standing, perhaps, for the severed neck, is placed at the left. The head has a decidedly porcine look, yet it may have been intended for a raccoon or an opossum.
