That trembling was a curious sensation beneath his hands. At first it was no more than might be caused by the passing of a heavy van in the street; only there was no van. But it had increased, with spasms and recoils, till it resembled a continuous shudder as of a living rigid body. It began also to tilt slightly this way and that.
Now all this, Laurie knew well, meant nothing at all--or rather, it need not. And when the movement passed again through all the reverse motions, sinking at last into complete stillness, he was conscious of disappointment. A moment later, however, as he glanced up again at the medium in the cabinet, he drew his breath sharply, and Mr. Jamieson, at the sound, wheeled his head swiftly to look.
There, in the cabinet, somewhere overhead behind the curtain, a faint but perfectly distinct radiance was visible. It was no more than a diffused glimmer, but it was unmistakable, and it shone out faintly and clearly upon the medium's face. By its light Laurie could make out every line and every feature, the drooping clipped moustache, the strong jutting nose, the lines from nostril to mouth, and the closed eyes. As he watched the light deepened in intensity, seeming to concentrate itself in the hidden corner at the top.
Then, with a smooth, steady motion it emerged into full sight, in appearance like a softly luminous globe of a pale bluish color, undefined at the edges, floating steadily forward with a motion like that of an air balloon, out into the room. Once outside the cabinet it seemed to hesitate, hanging at about the height of a man's head--then, after an instant, it retired once more, re-entered the cabinet, disappeared in the direction from which it had come, and once more died out.
Well, there it had been; there was no doubt about it.... And Laurie was unacquainted with any mechanism that could produce it.
The clergyman too had seemed affected. He had watched, with turned-back head, the phenomenon from beginning to end, and at the close, with a long indrawing of breath, had looked once at Laurie, licked his dry lips with a motion that was audible in that profound silence, and once more dropped his eyes. The ladies had been silent, and all but motionless throughout.
Well, the rest had happened comparatively quickly.
Once more, after the lapse of a few minutes, the radiance had begun to reform; but this time it had emerged almost immediately, diffused and misty like a nebula; had hung again before the cabinet, and then, with a strange, gently whirling motion, had seemed to arrange itself in lines and curves.
