1906. This is a dissertation on practical psychometry, its value and how it is mastered. The psychometrist can use his gift anywhere; any object can be made to give up its history, to reveal its past, present and future surroundings. This is a book of the world, of nature, and of other worlds, because nothing is hidden or undiscoverable from the psychometrist. The author states that those of his readers which will give time and patience to development will be amply rewarded, and they will not be willing to lose the power once it is acquired.
