TO RESTORE SIGHT
I learn from Nice (says a writer in the Pall MaD Gazette) that M. Kann; a Polish savant, who is a soldier in the French Foreign Legion, lias invented an apparatus by which he hopes to restore the sight of men who havu lost their sight through wounds. The apparatus is in the form of a mask, or half-mask, which is placed on the face of the blind man, and connected by wires with a portable electrical induction apparatus. Lenses, total reflection prism*, a camera filtering the light rays, and phoresceitt plaques complete the apparatus. The principle of the invention is progressive re-education, varying in period with each subject and the length of time which the blindness 'has existed. Blind men who have been subjected to the experiment for a few hours daily have successively perceived, instead of the yellowish grey tint which habitually replaces sight: (1) all the colours of the spectrum . beginning with red; (2) natural white light; (3) shadows and their objects in this light.
