"In a short time, however, Katie--as the familiar of Miss B. was termed--thought she would be able to 'materialise' herself so far as to present the whole form, if we arranged the corner cupboard so as to admit of her doing so. Accordingly we opened the door, and from it suspended a rug or two opening in the centre, after the fashion of a Bedouin Arab's tent; formed a semicircle; sat and sang Longfellow's 'Footsteps of Angels.' Therein occurs the passage, 'Then the forms of the departed enter at the open door.' And, lo and behold! though we had left Miss B. tied and sealed to her chair and clad in an ordinary black dress somewhat voluminous as to the skirts, a tall, female figure, draped classically in white, with bare arms and feet, did enter at the open door, or rather down the centre from between the two rugs, and stood statuelike before us, spoke a few words, and retired; after which we entered the Bedouin tent and found pretty Miss B. with her dress as before, knots and seals secure, and her boots on! This was Form No. 1, the first I had ever seen. It looked as material as myself; and on a subsequent occasion--for I have seen it several times--we took four very good photographic portraits of it by magnesium light. The difficulty I still felt, with the form as with the faces, was that it seemed so thoroughly material and flesh-and-blood-like." It is not my intention to speak of the multitude of early materialisations. As Mr Podmore points out, at these manifestations practically no precautions were taken against trickery. There was nothing, so far as can be discovered, to throw any hindrance in the way of the medium, if she chose, impersonating the spirit by exhibiting a mask through the opening of the curtain or by dressing herself up and walking about the room. Nor were there any collateral circumstances to justify belief in the genuineness of the manifestations. Nevertheless, Miss Cook's claims attracted the attention of Sir William Crookes. He attended several _séances_--one, once, at the house of Mr Luxmoor, when "Katie" was standing before him in the room. He had distinctly heard from behind the curtain the sobbing and moaning habitually made by Miss Cook during such _séances_. At another _séance_, held at his own house, 12th March 1874, "Katie," robed in white, came to the opening of the curtain and summoned him to the assistance of her medium. The man of science instantly obeyed the call, and found Miss Cook, attired in her ordinary black velvet dress, prone on the sofa. On another occasion he declares he saw two forms together in a good light; more than this, he actually procured a photograph of "Katie." But of this I will speak later, when I come to discuss spirit photography.
