“The Psychometric Medium has the power of feeling and correctly describing the characteristics of persons with whose spheres he or she is brought into sympathy or contact. The power is generally exercised by placing to the forehead, the perceptive region of the brain, anything which has been intimately connected with the person, as a piece of his hair, his handwriting, or a well-worn article of dress. Some will thus read a sealed letter or the mottoes enclosed in nuts....
“Pictorial Mediumship differs from the Symbolic chiefly in the circumstance that the things seen and described by the medium do not in reality exist as material facts, but are only representations, prefiguring or bodying-forth a spiritual or psychical truth....
“The next is the Duodynamic Medium, a word signifying two powers, he being capable of exhibiting two or more forms of mediumship at the same time. These compound media, maturely developed, are said to be comparatively rare.
“The last in this Onward stratum is the Developing Medium, through whom spirits can very usefully assist in developing the mediumistic faculty in others. They have the power of harmonising the influences which affect them, and of rendering media passive to the action of the spirits who are seeking the control of their organisms.”
As regards the “Upward stratum,” the following definitions are given:—
“The Therapeutic Medium is one who effects the cure of many diseases through the sympathetic power of seeing and describing minutely the disorganized parts of the body, and directing the necessary treatment; sometimes the manipulating mediumship is added, when the medium not only sees the source of mischief, but also makes curative mesmeric passes at the same time.
“Next, we have the Missionary Medium, who is irresistibly compelled to go, without knowing why or whither, wherever the spirit guides him. Under this controlling influence, media have been made to travel nearly all over the civilized world, generally without purse or scrip, or any personal knowledge of the places; the spirits raising up friends and helpers at every step as they are required.” Writing of a Missionary Medium known to himself, Mr. Grant adds the following:—“I am acquainted with a medium of this class in Maidstone, who is too weak in body to walk far in his ordinary state, yet, under this influence, he is often made to walk long distances without feeling fatigue, at the most unreasonable hours of day or night, and he has several times been instantaneously transported from one place to another, miles apart.”
“Speaking mediumship,” writes the author quoted, “is a most useful and instructive faculty.... In most cases speakers have to be entranced, that is, their spirits have to be removed from the body for a time, in order to give the acting spirit full control; but when this has to be done the medium is but little advanced from the personating mediumship, which is one of the successive stages which a fully-developed speaking medium generally passes through. Many of our most celebrated and effective preachers and speakers have been, or are, really speaking media, under the guidance of spirits, without its being suspected or understood even by themselves. This is, indeed, ‘inspiration.’
“The Clairvoyant Medium follows next in order, and is in advance of the telegraphic, because he is able to see the scenes that are actually transpiring at the time in another place, no matter how far distant.
“The Impressional Medium is generally one who has advanced through the neurologic, sympathetic, clairlative, and psychologic phases, and thus become so easily and thoroughly impressible by his guardian spirit that the medium appears to live a double life, the conditions and circumstances of both states of existence finding a ready expression through his organism at all times without his being entranced, the spiritual existence becoming as much as the physical his normal state.” pp. 7-18.
