Riassunto

Excerpt from The Microscope, Vol. 49: House-Infesting Spring-Tail

The blind are able to see, and apparently to get thoughts with their fingers. Prescott, the great historian, says: The blind man sees little outside of the circle drawn by his extended arms, but within that circle he sees more than those whose eyes are sound.

By resting the finger on the throat of a singer, a certain blind person can follow notes covering two octaves with her own voice, or by placing her hand on the frame of'the piano, she can distinguish between two notes not more than halfa tone apart. By moving her hand over the face of a visitor she is enabled to detect shades of emo tion which the normal sensitive eye cannot differentiate.

It has been reported that gray matter brain-cells of perception have been dissected out of the finger tips of the blind.

If you will examine the inside of your finger-tips with a magnifying glass of even moderate power you will find the skin all in ridges, which preserve the shape of the finger-end. Standing point up beneath all these ridges in the tactile surfaces of the skin are the so-called corpuscles of Pacini. These corpuscles which are arranged in the exact semblance of the keys of a piano, are said by Meissner to crepitate and give forth a different sound in every age of each person.

This Pacinian corpuscle contains Within its lining mem branes a nerve-trunk, an artery, and a vein.
