Carry Photo Messages In Eyes.

Spies, engaged tn a llfe-and-death business, have devised extraordinarily ingenious methods of concealment since history began. No means could be more remarkable, however, than that used by ~ the Russian bolshevlkl for getting messages through the enemy lines. The inside skin of an eggshell Is pasted on glass, and reduced with a microtome knife to almost impalpable thinness. It is then sensitized, and a microscopic message photographed upon It. Removed from the glass It is spread with a brush on the spy’s eyeball, under the lid. It does not inconvenience the carrier, and being quite transparent It Is practically In visible. —Popular Mechanics Magazine
