Moreover, astronomers themselves had not, at first, evinced any anxiety about the collision, so far as it affected the fate of humanity, and the astronomical journals (which alone retained any semblance of authority) had as yet referred to the subject simply as a computation to be verified. Scientists had treated the problem as one of pure mathematics, regarding it only as an interesting case of celestial mechanics. In the interviews to which they had been subjected they had contented themselves with saying that a collision was possible, even probable, but of no interest to the public. Meanwhile, a new message was received by telephone, this time from Mount Hamilton in California, which produced a sensation among the chemists and physiologists: “Spectroscopic observation establishes the fact that the comet is a body of considerable density, composed of several gases the chief of which is carbonic-oxide.” Matters were becoming serious. That a collision with the earth would occur was certain. If astronomers were not especially preoccupied by this fact, accustomed as they were for centuries to consider these celestial conjunctions as harmless: if the most celebrated even of their number had, at last, coldly shown the door to the many beardless reporters constantly importuning them, declaring that this prediction was of no interest to the people at large and was a strictly astronomical question which did not concern them, physicians, on the other hand, had begun to agitate the subject and to discuss gravely, among each other, the possibilities of asphyxia, or poisoning. Less indifferent to public opinion, so far from turning a cold shoulder to the journalists, they had welcomed them, and in a few days the subject suddenly entered upon a new phase. From the domain of astronomy it had passed into that of philosophy, and the name of every well-known or famous physician appeared in large letters on the title-pages of the daily papers; their portraits were reproduced in the illustrated journals, and the formula, “Interviews on the Comet,” was to be seen on every hand. Already, even, the variety and diversity of conflicting opinions had created hostile camps, which hurled at each other the most grotesque abuse, and asserted that all physicians were “charlatans eager for notoriety.” In the mean time the director of the Paris observatory having at heart the interests of science, was profoundly disturbed by an uproar which had more than once, on former occasions, singularly misrepresented astronomical facts. He was a venerable old man who had grown gray in the study of the great problems of the constitution of the universe. His utterances were respected by all, and he had decided to make a statement to the press in which he declared that all conjectures, made prior to the technical discussion authorized by the Institute, were premature.
