"But though I have written this report without stopping to answer the objections and difficulties which arise at every line, though I have been contented myself with setting forth the logical and almost inevitable sequence of the deductions which led up to my theory. I should be failing in respect to the academy and to the public if I allowed it to be believed that I am not fully conscious of the weight of those objections and difficulties. I did not, however, consider this a reason for abandoning my task. Though it be our duty to bow when science utters a formal veto, on the other hand duty orders us to persist when science is content merely to confess its ignorance. This is the twofold principle which I observed in seeking no longer the source of the projections, but rather the manner in which they were able to appear, for that is where the whole problem lies. It is easy to declare that they emanate from Venus; it is not easy to explain how they travel through space and how they exercise their action, at a distance of many millions of miles, on an imperceptible screen with a surface of three or four hundred square feet. I am confronted with physical laws which I am not entitled to transgress. I am entitled at most to advance where science is obliged to be mute.
"Therefore and without any sort of discussion I admit that we are debarred from supposing that light can be the agent of the transmissions which have been observed. The laws of diffraction indeed are absolutely opposed to the strictly rectilinear propagation of luminous rays and hence to the formation and reception of pictures at the exceptional distances actually under consideration. Not only are the laws of geometrical optics merely a somewhat rough approximation, but the complicated refractions which would inevitably occur in the atmospheres of the earth and Venus would disturb the optical images. The veto of science therefore is peremptory in so far as the possibility of these optical transmissions is concerned.
"For that matter, I should be quite willing to believe that the inhabitants of Venus have already tried to correspond with us through the intermediary of luminous signals and that, if they abandoned their endeavours, this was precisely because the imperfection of our human science made them useless. We know in fact that Lowell and Schiaparelli saw on the face of Venus brilliant specks and a transient gleam which they themselves attributed either to volcanic eruptions or, as is more probable, to the attempts at communication of which I have spoken.
"But science does not prevent us from asking ourselves whether, after the failure of these attempts, the inhabitants of Venus did not resort to another method of correspondence. How can we avoid thinking, for instance, of the X-rays, whose strictly rectilinear path would allow of the formation of pictures so clear that one could wish for nothing better? In fact it is not impossible that these rays are employed for the emission received on the Meudon screen, though the quality of the light when analyzed in the spectroscope makes the supposition highly improbable. But how are we to explain by means of X-rays the taking of the terrestrial views of which we saw the moving outline on the screen? We know, of course, if we go back to the concrete example to which I referred just now, we know that neither the brothers Montgolfier nor the surrounding landscape emitted X-rays. It is not therefore through the medium of these rays that the Venusians can have secured the instantaneous photographs which they afterwards transmitted to us.
"Well, this exhausts all the possibilities of an explanation which can be referred to the present data of science. I declare positively that to-day, in this essay, I should not have dared to venture into the domain of theory and to suggest a solution in which my own labours are involved, if Noël Dorgeroux had not in a manner authorized me to do so. The fact is that, twelve months ago, I issued a pamphlet, entitled An Essay on Universal Gravitation, which fell flat on publication, but which must have attracted Noël Dorgeroux's particular attention, because his nephew, Victorien Beaugrand, found my name written among his papers and because Noël Dorgeroux cannot have known my name except through this pamphlet. Nor would he have taken the trouble to write it down, if the theory of the rays of gravitation which I developed in my pamphlet had not appeared to him to be exactly adapted to the problem raised by his discovery?
"I will therefore ask the reader to refer to my pamphlet. He will there find the results, vague but by no means negligible, which I was able to explain by my experiments with this radiation. He will see that it is propagated in a strictly rectilinear direction and with a speed which is thrice that of light, so that it would not take more than 46 seconds to reach Venus at the time when she is nearest to the earth. He will see lastly that, though the existence of these rays, thanks to which universal attraction is exercised according to the Newtonian laws, is not yet admitted and though I have not yet succeeded in making them visible by means of suitable receivers, I nevertheless give proofs of their existence which must be taken into consideration. And Noël Dorgeroux's approval also is a proof that they must not be neglected.
"On the other hand, we have the right to believe that, while our poor rudimentary science may, after centuries and centuries of efforts, have remained ignorant of the essential factor of the equilibrium of the planets, the Venusian scientists long since passed this inferior stage of knowledge and that they possess photographic receivers which allow films to be taken by means of the rays of gravitation and this by methods of truly wonderful perfection. They were therefore waiting. Looking down upon our planet, knowing all that happened here, witnessing our helplessness, they were waiting to communicate with us by the only means that appeared to them possible. They were waiting, patiently and persistently, formidably equipped, sweeping our soil with the invisible sheaves of rays assembled in their projectors and receivers, searching and prying into every nook and corner.
"And one day the wonderful thing happened. One day the shaft of rays struck the layer of substance on the screen where and where alone the spontaneous work of chemical decomposition and immediate reconstitution could be performed. On that day, thanks to Noël Dorgeroux and thanks to luck, as we must confess, for Noël Dorgeroux was pursuing an entirely different series of experiments on that particular day, the Venusians established the connection between the two planets. The greatest fact in the history of the world was accomplished.
"There is evidence even that the Venusians knew of Noël Dorgeroux's earlier experiments, that they realized their importance, that they interested themselves in his labours and that they followed the events of his life, for it is now many years since they took the pictures showing how his son Dominique was killed in the war. But I will not recapitulate in detail each of the films displayed at Meudon. This is a work which anybody can now perform in the light of the theory which I am setting forth. But we must consider attentively the process by which the Venusians tried to give those films a sort of uniformity. It has been rightly said that the sign of the Three Eyes is a trade-mark, like the mark of any of our great cinematograph-producers, a trade-mark also very strikingly proves the superhuman resources possessed by the Venusians, since they succeed in giving to those Three Eyes, which have no relation to our human eyes, not only the expression of our eyes but something much more impressive, the expression of the eyes of the person destined to be the principal character in the film.
"But why was this particular mark chosen? Why eyes and why three? At the stage which we have now reached, need we answer this question? The Venusians themselves have furnished the reply by showing us that apparently absurd film in which Shapes assuredly lived and moved in our sight in accordance with the lines and principle of Venusian life. Were we not the breathless spectators of a picture taken among them and from them? Did we not behold, to make a companion picture to the death of Louis XVI, an incident representing the martyrdom of some great personage whom the executioners tore to pieces with their three hands, severing from his body a sort of shapeless head provided with three eyes?
