In the sixth circle the visible world begins, which only appears to be so sharply divided from the other side in consequence of the fickleness of our organs of sense. In reality the transition is a very gradual one, and there are people who live on a higher stage of knowledge because their perceptions and sensations are more delicate than those of others. Great seers are enabled to see manifestations of force where ordinary people can perceive nothing. S. W. sees Magnesor as a white or bluish vapour, which chiefly develops when good spirits are near. Connesor is a dark vapour-like fluid, which, like Magnesor, develops on the appearance of "black" spirits. For instance, the night before the beginning of great visions the shiny vapour of Magnesor spreads in thick layers, out of which, the good spirits grow to visible white forces. It is just the same with Connesor. But these powers have their different mediums. S. W. is a Magnesor medium, as were the Prophetess of Prevorst and Swedenborg. The materialisation mediums of the spiritualists are mostly Connesor mediums, because materialisation takes place much more easily through Connesor on account of its close connection with the properties of matter. In the summer of 1900 S. W. tried several times to produce the circles of matter, but she never arrived at other than vague and incomprehensible hints and afterwards spoke no more about this. _Conclusion._--The really interesting and valuable séances came to an end with the production of the system of powers. Before this a gradual decline in the vividness of the ecstasies was noticeable. Ulrich von Gerbenstein came increasingly to the front, and filled up the séances with his childish chatter. The visions which S. W. had in the meantime likewise seem to have lost vividness and plasticity of formation, for S. W. was afterwards only able to feel pleasant sensations in the presence of good spirits, and disagreeableness in that of bad spirits. Nothing new was produced. There was something of uncertainty in the trance talks, as if feeling and seeking for the impression which she was making upon the audience, together with an increasing staleness in the content. In the outward behaviour of S. W. there arose also a marked shyness and uncertainty, so that the impression of wilful deception became ever stronger. The writer therefore soon withdrew from the séances. S. W. experimented afterwards in other circles, and six months after my leaving was caught cheating _in flagranti delicto_. She wanted to arouse again by spiritualistic experiments the lost belief in her supernatural powers; she concealed small objects in her dress, throwing them up in the air during the dark séance. With this her part was played out. Since then, eighteen months have passed during which I have not seen S. W. I have learnt from an observer who knew her in the earlier days, that she has now and again strange states of short duration during which she
