The tattooed immortal with cocoa skin sat forward, his magic vibrating in the air around him.
Essential are vibrating membranes between the cartilaginous framework, and next, special muscles for regulating the tension.
It consists in attaching to the loop or ventral segment of a vibrating body, e.g.
Considering the great variety of spectra, which one and the same body may possess, the idea lies near that free electrons may temporarily attach themselves to a molecule or detach 'themselves from it, thereby altering the constitution of the vibrating system.
A limit to homogeneity of radiation is ultimately set by the so-called Doppler effect, which is the change of wave-length due to the translatory motion of the vibrating molecule from or towards the observer.
