"You have doubtless heard of the sensing of sealed letters spoken of as pure clairvoyance. But this phase of phenomena properly belongs to the realm of Psychometry. Letters frequently prove to be very excellent connecting links in psychometric experiments. I advise the student to begin with old letters. He will be surprised to discover how readily he will begin to receive psychic impressions from the letters--either from the person who wrote them, or from the place in which they were written, or from some one connected with their subsequent history. One of the most interesting experiments I ever witnessed in Psychometry was that in which a letter that had been forwarded from place to place, until it had gone completely around the globe, was psychometrized by a young Hindu maid. Although ignorant of the outside world of foreign lands, the young women was able to picture the people and scenery of every part of the globe in which the letter had traveled. Her report was really an interesting 'travelogue' of a trip around the world, given in tabloid form. The student may obtain some interesting results in psychometrizing old letters--but let him always be conscientious about it, and be careful to refrain from divulging the secrets that will become his during the course of these experiments. Let him be honorable on the psychic plane as well as on the physical plane--more so, rather than less so, in fact." Varieties of Psychometry. Another investigator along these lines gives the following instructive comments regarding the practice of psychometric power: "Persons of a highly-strung nervous organization, with large perceptive faculties make the best psychometrists. Phlegmatic people seldom psychometrize clearly, and usually lack receptivity to the finer forces. Letters, clothes, hair, coins, ornaments, or jewels--in fact, almost any article which has belonged to, or has been worn by, its possessor for any length of time, will suffice to enable the psychometrist to relate himself to, and glimpse impressions of, the personal sphere of that individual. Some psychometrists succeed better with certain kinds of objects than with others. Metals and minerals are not good 'conductors'--if we may use that term--to some operators; while they are very satisfactory to others. In the same way, some psychometrists are very good character readers, others are very successful in the diagnosis of diseases; some can read the book of Nature, while to others it is a sealed book, or nearly so, but they are able to gauge the mental qualifications of their visitors, while others realize their moral and spiritual states. Again, some read the Past, and enter into the Present states or condition of their clients, while others are successful in exercising prophetical prevision. These differences may be modified, and the boundaries of the perceptive power may be extended by self-study, experiment, and culture;
