but not morbidly fond, of reading—chiefly fiction pervaded with a vaguely pious optimism—sleeps well, and rarely dreams. He is, in fact, the very last person to evolve a fantastic fable. Indeed, so far from forcing this story upon the world, he has been singularly reticent on the matter. He meets inquirers with a certain engaging—bashfulness is almost the word, that disarms the most suspicious. He seems genuinely ashamed that anything so unusual has occurred to him.
It is to be regretted that Plattner’s aversion to the idea of post-mortem dissection may postpone, perhaps for ever, the positive proof that his entire body has had its left and right sides transposed. Upon that fact mainly the credibility of his story hangs. There is no way of taking a man and moving him about in space, as ordinary people understand space, that will result in our changing his sides. Whatever you do, his right is still his right, his left his left. You can do that with a perfectly thin and flat thing, of course. If you were to cut a figure out of paper, any figure with a right and left side, you could change its sides simply by lifting it up and turning it over. But with a solid it is different. Mathematical theorists tell us that the only way in which the right and left sides of a solid body can be changed is by taking that body clean out of space as we know it—taking it out of ordinary existence, that is, and turning it somewhere outside space. This is a little abstruse, no doubt, but anyone with any knowledge of mathematical theory will assure the reader of its truth. To put the thing in technical language, the curious inversion of Plattner’s right and left sides is proof that he has moved out of our space into what is called the Fourth Dimension, and that he has returned again to our world. Unless we choose to consider ourselves the victims of an elaborate and motiveless fabrication, we are almost bound to believe that this has occurred.
So much for the tangible facts. We come now to the account of the phenomena that attended his temporary disappearance from the world. It appears that in the Sussexville Proprietary School, Plattner not only discharged the duties of Modern Languages Master, but also taught chemistry, commercial geography, book-keeping, shorthand, drawing, and any other additional subject to which the changing fancies of the boys’ parents might direct attention. He knew little or nothing of these various subjects, but in secondary as distinguished from Board or elementary schools, knowledge in the teacher is, very properly, by no means so necessary as high moral character and gentlemanly tone. In chemistry he was particularly deficient, knowing, he says, nothing beyond the Three Gases (whatever the three gases may be). As, however, his pupils began by knowing nothing, and derived all their information from him, this caused him (or anyone) but little inconvenience for several terms. Then a little boy named Whibble joined the school, who had been educated (it seems) by some mischievous relative into an inquiring habit of mind. This little boy followed Plattner’s lessons with marked and sustained interest, and in order to exhibit his zeal on the subject, brought, at various times, substances for Plattner to analyse. Plattner, flattered by this evidence of his power of awakening interest, and trusting to the boy’s ignorance, analysed these, and even made general statements as to their composition. Indeed, he was so far stimulated by his pupil as to obtain a work upon analytical chemistry, and study it during his supervision of the evening’s preparation. He was surprised to find chemistry quite an interesting subject.
So far the story is absolutely commonplace. But now the greenish powder comes upon the scene. The source of that greenish powder seems, unfortunately, lost. Master Whibble tells a tortuous story of finding it done up in a packet in a disused limekiln near the Downs. It would have been an excellent thing for Plattner, and possibly for Master Whibble’s family, if a match could have been applied to that powder there and then. The young gentleman certainly did not bring it to school in a packet, but in a common eight-ounce graduated medicine bottle, plugged with masticated newspaper. He gave it to Plattner at the end of the afternoon school. Four boys had been detained after school prayers in order to complete some neglected tasks, and Plattner was supervising these in the small classroom in which the chemical teaching was conducted. The appliances for the practical teaching of chemistry in the Sussexville Proprietary School, as in most small schools in this country, are characterised by a severe simplicity. They are kept in a small cupboard standing in a recess, and having about the same capacity as a common travelling trunk. Plattner, being bored with his passive superintendence, seems to have welcomed the intervention of Whibble with his green powder as an agreeable diversion, and, unlocking this cupboard, proceeded at once with his analytical experiments. Whibble sat, luckily for himself, at a safe distance, regarding him. The four malefactors, feigning a profound absorption in their work, watched him furtively with the keenest interest. For even within the limits of the Three Gases, Plattner’s practical chemistry was, I understand, temerarious.
They are practically unanimous in their account of Plattner’s proceedings. He poured a little of the green powder into a test-tube, and tried the substance with water, hydrochloric acid, nitric acid, and sulphuric acid in succession. Getting no result, he emptied out a little heap—nearly half the bottleful, in fact—upon a slate and tried a match. He held the medicine bottle in his left hand. The stuff began to smoke and melt, and then—exploded with deafening violence and a blinding flash.
The five boys, seeing the flash and being prepared for catastrophes, ducked below their desks, and were none of them seriously hurt. The window was blown out into the playground, and the blackboard on its easel was upset. The slate was smashed to atoms. Some plaster fell from the ceiling. No other damage was done to the school edifice or appliances, and the boys at first, seeing nothing of Plattner, fancied he was knocked down and lying out of their sight below the desks. They jumped out of their places to go to his assistance, and were amazed to find the space empty. Being still confused by the sudden violence of the report, they hurried to the open door, under the impression that he must have been hurt, and have rushed out of the room. But Carson, the foremost, nearly collided in the doorway with the principal, Mr. Lidgett.
Mr. Lidgett is a corpulent, excitable man with one eye. The boys describe him as stumbling into the room mouthing some of those tempered expletives irritable schoolmasters accustom themselves to use—lest worse befall. “Wretched mumchancer!” he said. “Where’s Mr. Plattner?” The boys are agreed on the very words. (“Wobbler,” “snivelling puppy,” and “mumchancer” are, it seems, among the ordinary small change of Mr. Lidgett’s scholastic commerce.)
Where’s Mr. Plattner? That was a question that was to be repeated many times in the next few days. It really seemed as though that frantic hyperbole, “blown to atoms,” had for once realised itself. There was not a visible particle of Plattner to be seen; not a drop of blood nor a stitch of clothing to be found. Apparently he had been blown clean out of existence and left not a wrack behind. Not so much as would cover a sixpenny piece, to quote a proverbial expression! The evidence of his absolute disappearance, as a consequence of that explosion, is indubitable.
It is not necessary to enlarge here upon the commotion excited in the Sussexville Proprietary School, and in Sussexville and elsewhere, by this event. It is quite possible, indeed, that some of the readers of these pages may recall the hearing of some remote and dying version of that excitement during the last summer holidays. Lidgett, it would seem, did everything in his power to suppress and minimise the story. He instituted a penalty of twenty-five lines for any mention of Plattner’s name among the boys, and stated in the schoolroom that he was clearly aware of his assistant’s whereabouts. He was afraid, he explains, that the possibility of an explosion happening, in spite of the elaborate precautions taken to minimise the practical teaching of chemistry, might injure the reputation of the school; and so might any mysterious quality in Plattner’s departure. Indeed, he did everything in his power to make the occurrence seem as ordinary as possible. In particular, he cross-examined the five eye-witnesses of the occurrence so searchingly that they began to doubt the plain evidence of their senses. But, in spite of these efforts, the tale, in a magnified and distorted state, made a nine days’ wonder in the district, and several parents withdrew their sons on colourable pretexts. Not the least remarkable point in the matter is the fact that a large number of people in the neighbourhood dreamed singularly vivid dreams of Plattner during the period of excitement before his return, and that these dreams had a curious uniformity. In almost all of them Plattner was seen, sometimes singly, sometimes in company, wandering about through a coruscating iridescence. In all cases his face was pale and distressed, and in some he gesticulated
