We now approach a subject which cannot be omitted in any impartial sketch of the evidences of Spiritualism, since it is that which furnishes perhaps the most unassailable demonstration it is possible to obtain, of the objective reality of spiritual forms, and also of the truthful nature of the evidence furnished by seers when they describe figures visible to themselves alone. It has been already indicated—and it is a fact, of which the records of Spiritualism furnish ample proof—that different individuals possess the power of seeing such forms and figures in very variable degrees. Thus, it often happens at a séance, that some will see distinct lights of which they will describe the form, appearance and position, while others see nothing at all. If only one or two persons see the lights, the rest will naturally impute it to their imagination; but there are cases in which only one or two of those present are unable to see them. There are also cases in which all see them, but in very different degrees of distinctness; yet that they see the same objects is proved by their all agreeing as to the position and the movement of the lights. Again, what some see as merely luminous clouds, others will see as distinct human forms, either partial or entire. In other cases all present see the form—whether hand, face, or entire figure—with equal distinctness. Again, the objective reality of these appearances is sometimes proved by their being touched, or by their being seen to move objects—in some cases heard to speak, in others seen to write, by several persons at one and the same time; the figure seen or the writing produced being sometimes unmistakably recognizable as that of some deceased friend. A volume could easily be filled with records of this class of appearances, authenticated by place, date, and names of witnesses; and a considerable selection is to be found in the works of Mr. Robert Dale Owen.
