When re-absorbed, it leaves no trace upon the garments through which it has passed.
This is wonderful enough, but far more fantastic is what has still to be told. The most marked property of this ectoplasm, very fully illustrated in the photographs, is that it sets or curdles into the shapes of human members--of fingers, of hands, of faces, which are at first quite sketchy and rudimentary, but rapidly coalesce and develop until they are undistinguishable from those of living beings. Is not this the very strangest and most inexplicable thing that has ever yet been observed by human eyes? These faces or limbs are usually the size of life, but they frequently are quite miniatures. Occasionally they begin by being miniatures, and grow into full size. On their first appearance in the ectoplasm the limb is only on one plane of matter, a mere flat appearance, which rapidly rounds itself off, until it has assumed all three planes and is complete. It may be a mere simulacrum, like a wax hand, or it may be endowed with full power of grasping another hand, with every articulation in perfect working order.
The faces which are produced in this amazing way are worthy of study. They do not appear to have represented anyone who has ever been known in life by Doctor Geley. My impression after examining them is that they are much more likely to be within the knowledge of the subject, being girls of the French lower middle class type, such as Eva was, I should imagine, in the habit of meeting. It should be added that Eva herself appears in the photograph as well as the simulacra of humanity. The faces are, on the whole, both pretty and piquant, though of a rather worldly and unrefined type. The latter adjective would not apply to the larger and most elaborate photograph, which represents a very beautiful young woman of a truly spiritual cast of face. Some of the faces are but partially formed, which gives them a grotesque or repellant appearance. What are we to make of such phenomena? There is no use deluding ourselves by the idea that there may be some mistake or some deception. There is neither one nor the other. Apart from the elaborate checks upon these particular results, they correspond closely with those got by Lombroso in Italy, by Schrenk-Notzing in Germany, and by other careful observers. One thing we must bear in mind constantly in considering them, and that is their abnormality. At a liberal estimate, it is not one person in a million who possesses such powers--if a thing which is outside our volition can be described as a power. It is the mechanism of the materialisation medium which has been explored by the acute brain and untiring industry of Doctor Geley, and even presuming, as one may fairly presume, that every materialising medium goes through the same process in order to produce results, still such mediums are exceedingly, rare. Dr. Geley mentions, as an analogous phenomenon on the material side, the presence of dermoid cysts, those mysterious formations, which rise as small tumors in any part of the body, particularly above the eyebrow, and which when opened by the surgeon are found to contain hair, teeth or embryonic bones. There is no doubt, as he claims, some rough analogy, but the dermoid cyst is, at least, in the same flesh and blood plane of nature as the foetus inside it, while in the ectoplasm we are dealing with an entirely new and strange development.
 Dr. Geley writes to me that they are unknown either to him or to the medium.
It is not possible to define exactly what occurs in the case of the ectoplasm, nor, on account of its vital connection with the medium and its evanescent nature, has it been separated and subjected to even the roughest chemical analysis which might show whether it is composed of those earthly elements with which we are familiar. Is it rather some coagulation of ether which introduces an absolutely new substance into our world? Such a supposition seems most probable, for a comparison with the analogous substance examined at Dr.
