How did Vera discover she had this gift of second sight?
Several cases have been reported in Russia recently of people who can detect colours with their fingers, and even see through solid and walls. One case concerns and eleven-year-old schoolgirl, Vera Petrova, who has normal vision but who can also perceive things with different parts of her skin, and through solid walls. This ability was first noticed by her father. One day she came into his office and happenedput her hands on the door of a locked safe. Suddenly she asked her father why he kept so many old newspapers locked away there, and even described the way they were done up in bundles. Vera's curious talent was broughtthe notice of a scientific research institute in the town of Ulyanovsk, near where she lives, and in April she was given a series of tests by a special commission of the Ministry of Health of the Russian Federal Republic. During these tests she was ableread a newspaper through an opaque screen and, stranger still, by moving her elbow over a child's game of Lotto she was abledescribe the figures and colours printed on it; and, in another instance, wearing stockings and slippers,make out with her foot the outlines and colours of a picture hidden under a carpet. Other experiments showed that her knees and shoulders had a similar sensitivity. During all these tests Vera was blindfold; and, indeed, except when blindfold she lacked the abilityperceive things with her skin. It was also found that although she could perceive things with her fingers this ability ceased the moment her hands were wet. ERIC DE MAUNY Seeing hands from The Listener
