Glasses to See Behind You.

4 A little aparatus that enables a man to see behind him as he walks along the street has just been put on the market in Paris. It is called the periscope and is the invention of Count Soulie de Cenac. The periscope consists of two tiny circular mirrors which can be attached to the outer edges of any ordinary eyeglasses. They swing on pivots

which enable the wear to adjust them to his eyes, QC to swing them down in a position in which they will be out of hie range of vision. They can also be adjusted to the focus of the eyes. . The inventor thinks the periscope will prove valuable especially tp do tectives who may desire to watch a person without his being aware of the fact that he Is being watched.
