4. Letters from unknown correspondents, and immediate answers written to queries made, and found in the most out-of-the-way mysterious places. 5. Appearance of objects unclaimed by anyone present. 6. Sounds of musical notes in the air wherever Madame Blavatsky desired they should resound. In the year 1858, the High Priestess was at the house of General Yakontoff at Pskoff, Russia. One night when the drawing-room was full of visitors, she began to describe the mediumistic feat of making light objects heavy and heavy objects light. "Can you perform such a miracle?" ironically asked her brother, Leonide de Hahn, who always doubted his sister's occult powers. "I can," was the firm reply. De Hahn went to a small chess table, lifted it as though it were a feather, and said: "Suppose you try your powers on this." "With pleasure!" replied Mme. Blavatsky. "Place the table on the floor, and step aside for a minute." He complied with her request. She fixed her large blue eyes intently upon the chess table and said without removing her gaze, "Lift it now." The young man exerted all his strength, but the table would not budge an inch. Another guest tried with the same result, but the wood only cracked, yielding to no effort. [Illustration: FIG. 34--MAHATMA LETTER ENVELOPE.] "Now, lift it," said Madame Blavatsky calmly, whereupon De Hahn picked it up with the greatest ease. Loud applause greeted this extraordinary feat, and the skeptical brother, so say the occultists, was utterly nonplussed. Madame Blavatsky, as recorded by Sinnett, stated afterwards that the above phenomenon could be produced in two different ways: "First, through the exercise of her own will directing the magnetic currents so that the pressure on the table became such that no physical force could move it; second, through the action of those beings with whom she was in constant communication, and who, although unseen, were able to hold the table against all opposition." The writer has seen similar feats performed by hypnotizers with good subjects without the intervention of any ghostly intelligences. In 1870 the Priestess of Isis journeyed through Egypt in company with a certain Countess K--, and endeavored to form a Spiritualistic society at Cairo, for the investigation of psychic phenomena, but things growing unpleasant for her she left the land of pyramids and papyri in hot haste. It is related of her that during this Egyptian sojourn she spent one night in the King's sepulchre in the bowels of the Great Pyramid of Cheops, sleeping in the very sarcophagus where once reposed the mummy of a Pharoah. Weird sights were seen by the entranced occultist and strange sounds were heard on that eventful occasion within the shadowy mortuary chamber of the pyramid. At times she would let fall mysterious hints of what she saw that night, but they were as incomprehensible as the riddles of the fabled Sphinx.
