He spoke of the accident with a casual air when he was in the breakfast-room, but Challis remarked a slight flush on the great scientist's face as he referred, perhaps a trifle too ostentatiously, to the incident. And although it is worthless as evidence, there is something rather suspicious in Challis's discovery of finely powdered glass in his library--a mere pinch on the parquet near the further window of the big room, several feet away from the table at which the Wonder habitually sat. Challis would never have noticed the glass, had not one larger atom that had escaped pulverisation, caught the light from the window and drawn his attention. But even this find is in no way conclusive. The Professor may quite well have walked over to the window, taken off his spectacles to wipe them and dropped them as he, himself, explained. While the crushing of some fragment of one of the lenses was probably due to the chance of his stepping upon it, as he turned on his heel to continue the momentarily interrupted conversation. It is hard to believe that so great a man as Grossmann could have been convulsed by a petty rage that found expression in some act of wanton destruction. His own brief account of the interview accords very well with the single reference to the Wonder which exists in the literature of the world. This reference is a footnote to a second edition of Grossmann's brochure entitled "An Explanation of Certain Intellectual Abnormalities reported in History" ("Eine Erklärung gewisser Intellektueller geschichtlich überlieferter Anormalen Erscheinungen"). This footnote comes at the end of Grossmann's masterly analysis of the Heinecken case and reads: "I recently examined a similar case of abnormality in England, but found that it presented no such marked divergence from the type as would demand serious investigation." And in his brief account of the interview rendered to Challis and Elmer, Herr Grossmann, in effect, did no more than draft that footnote. IV It must remain uncertain, now, whether or not Elmer would have persisted in his endeavour to exploit the Wonder to the confounding of Grossmann, despite Challis's explicit statement that he would do no more, not even if it were to save the reputation of the Royal Society. Elmer certainly had the virtue of persistence and might have made the attempt. But in one of his rare moments of articulate speech, the Wonder decided the fate of that threatened controversy beyond the possibility of appeal. He spoke to Challis that same afternoon. He put up his tiny hand to command attention and made the one clear statement on record of his own interests and ambitions in the world. Challis, turning from his discovery of the Professor's crushed glasses, listened in silence. "This Grossmann," the Wonder said, "was not concerned in my exemption?" Challis shook his head. "He is the last," the Wonder concluded with a fine brevity. "You and your kind have no interest in truth."
