Hetty's illness was long and serious; but before it was over Freeling was able to convince Dr. Abury of his own and his colleague's error, and to prove by a simple piece of surgery that Arthur's hideous grimaces were due to nothing worse than a purely physical impediment. The operation was quite a successful one; but though Greatrex's face has never since been liable to these curious contortions, the consequent relaxation of the muscles has given his features that peculiarly calm and almost impassive expression which everybody must have noticed upon them at the present day, even in moments of the greatest animation. The difficulty was how to break the cause of the temporary mistake to Hetty, and this they were unable to do until she was to a great extent convalescent. When once the needful explanation was over, and Arthur was able once more to kiss her with perfect freedom from any tinge of suspicion on her part, he felt that his paradise was at last attained. A few days before the deferred date fixed for their wedding, Freeling came into the doctor's drawing-room, where Hetty and Arthur were sitting together, and threw a letter with a French official stamp on its face down upon the table. "There," he said, "I find all the members of the Academie des Sciences at Paris are madmen also!" Hetty smiled faintly, and said with a little earnestness in her tone, "Ah, Dr. Freeling, that subject has been far too serious a one for both of us to make it pleasant jesting." "Oh, but look here, Miss Abury," said Freeling; "I have to apologise to Arthur for a great liberty I have ventured to take, and I think it best to begin by explaining to you wherein it consisted. The fact is, before you were ill, Arthur had just written a paper on the interrelations of energy, which he showed to that pompous old nincompoop, Professor Linklight. Well, Linklight being one of those men who can never see an inch beyond his own nose, had the incomprehensible stupidity to tell him there was nothing in it. Thereupon your future husband, who is a modest and self-depreciating sort of fellow, was minded to throw it incontinently into the waste-paper basket. But a friend of his, Harry Freeling, who flatters himself that he can see an inch or two beyond his own nose, read it over, and recognized that it was a brilliant discovery. So what does he go and do--here comes in the apologetic matter--but get this memoir quietly translated into French, affix a motto to it, put it in an envelope, and send it in for the gold medal competition of the Academie. Strange to say, the members of the Academie turned out to be every bit as mad as the author and his friend; for I have just received this letter, addressed to Arthur at my house (which I have taken the further liberty of opening), and it informs me that the Academie decrees its gold medal for physical discovery to M. Arthur Greatrex, of London, which is a subject of congratulation for us three,
