5. _Spiritual Forms._—These are either luminous appearances, sparks, stars, globes of light, luminous clouds, &c.; or, hands, faces, or entire human figures, usually covered with flowing drapery, except a portion of the face and hands. The human forms are often capable of moving solid objects, and are both visible and tangible to all present. In other cases they are only visible to seers, but when this is the case it sometimes happens that the seer describes the figure as lifting a flower or a pen, and others present see the flower or the pen apparently move by itself. In some cases they speak distinctly; in others the voice is heard by all, the form only seen by the medium. The flowing robes of these forms have in some cases been examined, and pieces cut off, which have in a short time melted away. Flowers are also brought, some of which fade away and vanish; others are real, and can be kept indefinitely. It must not be concluded that any of these forms are actual spirits; they are probably only temporary forms produced by spirits for purposes of test, or of recognition by their friends. This is the account invariably given of them by communications obtained in various ways; so that the objection once thought to be so crushing—that there can be no “ghosts” of clothes, armor, or walking-sticks—ceases to have any weight. 6. _Spiritual Photographs._—These, as just detailed, demonstrate by a purely physical experiment the trustworthiness of the preceding class of observations. We now come to the mental phenomena, of which the following are the chief: 1. _Automatic Writing._—The medium writes involuntarily; often matter which he is not thinking about, does not expect, and does not like. Occasionally definite and correct information is given of facts of which the medium has not, nor ever had, any knowledge. Sometimes future events are accurately predicted. The writing takes place either by the hand or through a planchette. Often the handwriting changes. Sometimes it is written backwards; sometimes in languages the medium does not understand. 2. _Seeing, or Clairvoyance and Clairaudience._—This is of various kinds. Some mediums see the forms of deceased persons unknown to them, and describe their peculiarities so minutely that their friends at once recognize them. They often hear voices, through which they obtain names, date, and place, connected with the individuals so described. Others read sealed letters in any language, and write appropriate answers.
