"During a 1923 test supervised by Eric Dingwall of the British Society for Psychical Research (SPR), Ossowiecki reportedly reproduced the contents of a triple-sealed envelope: a French sentence about wines of the Rhine, Moselle and Burgundy plus a crude drawing of a bottle, and correctly named the sequence of envelope colours. "

"Early in 1933 Theodore Besterman (SPR) ran a test with Ossowiecki using a drawing of an ink bottle sealed in a triple envelope; Ossowiecki described the contents and made a drawing that, Besterman confirmed, exactly matched the original. "

"In a test conducted in Paris by Gustave Geley (Institut Métapsychique International), Ossowiecki reportedly read the contents of a sealed envelope in which Geley had described an elephant bathing in a river having its trunk bitten off by a crocodile; Ossowiecki described a large animal — an elephant in water, blood, a wound and a fight with a crocodile.
