"Why don't you have a try yourself, Sir William," he said, with a not very friendly grin; "or won't what d'you call 'em work for its master? You had my thoughts for nothing, I'll give you twopence for yours." There was an ill-suppressed titter from the more frivolous portion of the spectators; but Lord Malvin turned round and looked at the young man with a frown of disapproval. There was something in that leonine head and those calm wise eyes which compelled him to silence. Then Herr Schmoulder, a famous savant from Berlin, spoke. "It would an interesting demonstration make," he said, "of der statement of der relative power that the strong and weak brain possesses if we could see der apparatus in operation upon der thought vibrations transformed of an intelligence which not equal to our own is." Mrs. Hoskin-Heath chimed in, her beautiful, silvery notes coming, after the deep, grave, guttural, like a peal of bells heard in the lull of a thunderstorm. "What a _good_ idea, Sir William!" she said. "I wish you would let me send for my footman. He is sure to be in the servants' hall. It would be so interesting to know his real opinion of me and my husband; and he certainly is a most consummate fool, and would be a thoroughly good subject for such an experiment. I brought him out of Gloucestershire. You know, he was one of the under-footmen at my brother's place, and I have been trying to train him, though with little success. I mean that he is too stolid to be shy, and, therefore, won't object at all, as some men would, to put the cap on and sit down here in the dark. He won't be frightened, I am sure." "By all means, Mrs. Hoskin-Heath," Gouldesbrough said with a smile. "No doubt one could not have a better subject, and I really shall be able to illustrate the difference between the relative values of brain-power by this means. You will all be able to notice the difference in the vividness and outline of the pictures or words that will appear." Sir William turned round for Wilson Guest, whom he proposed to send upon the mission, but could not find him. "I will ring for the butler," he said, "and tell him to fetch your man, Mrs. Hoskin-Heath." "Oh! don't do that," a voice said upon the second tier. "I--I--am--er--not feeling very well, Sir William, and I was going to ask your permission to go and sit down in the hall for a few minutes; I will tell one of your servants, they are sure to be about." The voice was the voice of Donald Megbie. He did not look at all ill, but he stepped down with a smile and went out of the laboratory, while everybody waited for the advent of Mrs. Hoskin-Heath's footman. Once more Sir William looked round to see if Wilson Guest had returned.
