Andrew Lang, another prominent investigator of psychic phenomena, gives the following interesting experiment in crystal-gazing: "I had given a glass ball to a young lady, Miss Baillie, who had scarcely any success with it. She lent it to Miss Leslie, who saw a large, square, old-fashioned red sofa covered with muslin (which she, afterward found in the next country-house she visited). Miss Baillie's brother, a young athlete, laughed at these experiments, took the ball into his study, and came back looking 'gey gash.' He admitted that he had seen a vision--somebody he knew, under a lamp. He said that he would discover during the week whether or not he had seen right. This was at 5:30 on a Sunday afternoon. On Tuesday, Mr. Baillie was at a dance in a town forty miles from his home, and met a Miss Preston. 'On Sunday,' he said, 'about half-past-five, you were sitting under a standard lamp, in a dress I never saw you wear, a blue blouse with lace over the shoulders, pouring out tea for a man in blue serge, whose back was toward me, so that I only saw the tip of his mustache.' 'Why, the blinds must have been up,' said Miss Preston. 'I was at Dulby,' said Mr. Baillie, and he undeniably was." Miss X., the well-known contributor to the English magazine, "Borderland," several years ago, made a somewhat extended inquiry into the phenomena of crystal-gazing. From her experiments, she made the following classification of the phenomena of crystal-vision, which I herewith reproduce for your benefit. Her classification is as follows: 1. Images of something unconsciously observed. New reproductions, voluntary or spontaneous, and bringing no fresh knowledge to the mind. 2. Images of ideas unconsciously acquired from others. Some memory or imaginative effect, which does not come from the gazer's ordinary self. Revivals of memory. Illustrations of thought. 3. Images, clairvoyant or prophetic. Pictures giving information as to something past, present, or future, which the gazer has no other chance of knowing. As a matter of fact, each and every form or phase of clairvoyance possible under other methods of inducing clairvoyant vision, is possible in crystal-gazing. It is a mistake to consider crystal-gazing as a separate and distinct form of psychic phenomena. Crystal-gazing is merely one particular form or method of inducing psychic or clairvoyant vision. If you will keep this in mind, you will avoid many common errors and misunderstandings in the matter. In order to give you the benefit of as many points of view as possible, I shall now quote from an old English writer on the subject of the use of the crystal. I do this realizing that sometimes a particular student will get more from one point of view, than from another--some particular phrasing will seem to reach his understanding, where others fail. The directions of the English authority are as follows:
