Vibrations 1959

My friend Rod, in Heidelberg, just sent me this quote he found in his reading of old journals and books:

Oct. 1959 Hibbert Journal, p124: "For Psychic Science—to give it a proper name—is securely based upon the indisputable fact that there are in nature vibratory frequencies unrecognized by orthodox physics, to which certain gifted people known as mediums are sensitive."
