The tension and rigidity of nerve tissue determines the amount of molecular oscillation. Petoskey, Mich., Aug. 13. Miss Helen Keller, the noted blind and deaf girl, has heard her first note of music. Like the voices of singing of angels, said Miss Keller to Miss Macey, her teacher. Light is transmitted by the vibration of ether at the rate of 186,300 miles per second.
Vibrations strike the retina of the eye and are carried inward over the optic nerve.
The retina forwards the vibratory impulses to the nerve which communicates between the brain and the organ of vision. The X-ray is a good illustration of light penetrating solid substances by ether vibration, yet it is not a therapeutical agent. Air and ether are vibratory transmitting mediums. Ether interpenetrates the atmosphere, as well as all material substances, liquid or solid. Etheric vibrations pass freely through opaque bodies as light penetrates transparent substances, with the same velocity as that of light.
