Meanwhile an extraordinary scene occurred, behind closed doors, at the headquarters of the Carnegie Institution in Washington. Joseph Smith, acting under Cosmo Versál's direction, had forwarded an elaborate _précis_ of the latter's argument, accompanied with full mathematical details, to the head of the institution. The character of this document was such that it could not be ignored. Moreover, the savants composing the council of the most important scientific association in the world were aware of the state of the public mind, and felt that it was incumbent upon them to do something to allay the alarm. Of late years a sort of supervisory control over scientific news of all kinds had been accorded to them, and they appreciated the fact that a duty now rested upon their shoulders. Accordingly, a special meeting was called to consider the communication from Cosmo Versál. It was the general belief that a little critical examination would result in complete proof of the fallacy of all his work, proof which could be put in a form that the most uninstructed would understand. But the papers, diagrams, and mathematical formulae had no sooner been spread upon the table under the knowing eyes of the learned members of the council, than a chill of conscious impuissance ran through them. They saw that Cosmo's mathematics were unimpeachable. His formulae were accurately deduced, and his operations absolutely correct. They could do nothing but attack his fundamental data, based on the alleged revelations of his new form of spectroscope, and on telescopic observations which were described in so much detail that the only way to combat them was by the general assertion that they were illusory. This was felt to be a very unsatisfactory method of procedure, as far as the public was concerned, because it amounted to no more than attacking the credibility of a witness who pretended to describe only what he himself had seen--and there is nothing so hard as to prove a negative. Then, Cosmo had on his side the whole force of that curious tendency of the human mind which habitually gravitates toward whatever is extraordinary, revolutionary, and mysterious.
