"Quite so, Mr. Dean," he said; "it is exactly as you suppose, the form, power, and vividness of the pictures upon the screen correspond exactly with the strength of the intellect of the person whose thoughts are making these pictures. You will find your strongly imaginative man, or your man whose brain is much turned inward upon himself, and who, for this very reason takes little part in the action or movement of life, will give a far more complete and vivid picture than any other. For example, assuming that the Bishop's valet is an ordinary servant and accompanied his Lordship to Palestine a few months ago, and saw exactly what his Lordship saw, that man's memories would not be thrown upon the screen with such wonderful vividness as his Lordship's were. He would not be able, in all probability, to produce a picture, a general impression, which is a real picture and not a photograph, and which so conveys the exact likeness of a place far more than any photograph could ever do. His thoughts would probably be represented by some special incident which had struck his fancy at the time and assumed a proportion in his mind which a cultured and logical faculty of thought would at once reject as being out of due proportion. And finally, in a precise ratio to the power of the brain--I do not mean to its health, or ill-health, its weight or size, I mean its pure _thinking_ power--so are the thoughts, when transformed into light, vivid or not vivid, as the case may be." Mrs. Hoskin-Heath turned to Lord Landsend, who was sitting beside her. Her pretty face wore a roguish smile as she whispered to him. "Billy, what an awful donkey _you_ must be." Lord Landsend looked at her for a moment. Then he answered-- "Well, you know, I am not at all sure that it is not a jolly good thing to be sometimes. I would not be that fellow Gouldesbrough for anything." She looked at him in amusement. There was something quite serious in the young man's face. "Why," she said, in a whisper, "what do you mean, Billy?" "I may not be clever," said Lord Landsend, "but I prefer to spend my life doing what amuses me, not what other people think I ought to do. At the same time I know men, and I know that scientific Johnny over there has got something on his mind which I should not care to have. Poor Tommy Decies had that look in his eyes the night before Ascot last year, poor Eustace Charliewood had it just before he went down to Brighton and shot himself; and you may take it from me, Mrs. Hoskin-Heath, that I know what I am talking about." "And now," said Sir William, looking up and down the rows of faces opposite him. "And now, which of you will submit himself to the next experiment?" Then Lord Landsend spoke. He was determined to "get his own back," as he would have put it, if possible.
