tered state of nerves, because there was a something in its face which seemed strangely and horribly familiar to him. As he looked, he recognized with a feeling of unspeakable aversion what it was of which the monkey remin ded him. It was making a series of hideous and apparently mocking grimaces-the very self-same grimaces which he had seen on his own features in the mirror during the last day or two! Horrible idea! He was descending to the level of the very monkeys!

The more he watched, the more absolutely identical the two sets of grimaces appeared to him to be. Could it be fancy or was it reality? Or might it be one more delusion, showing that his brain was now giving way entirely? He rubbed his eyes, steadied his attention, and looked again with the deepest interest. No, he could not be mistaken. The monkey was acting in every respect precisely as he himself had acted.

"Harry," he said, in a low and frightened tone, "look at this monkey. Is he mad? Tell me."

"My dear Arthur," replied his friend, with just a shade of expostulation in his voice, "you have really got madness on the brain at present. No, he isn't mad at all. He's as sane as you are, and that's saying a good deal, I can assure you."

'But, Harry, you can't have seen what he's doing. He's grimacing and contorting himself in the most extraordinary fashion."

'Well, monkeys often do grimace, don't they?" Harry Freeling answered coolly. "Take this brandy and you'll soon feel better."

"But they don't grimace like this one," Arthur persisted.

"No, not like this one, certainly. That's why I've got him here. I'm going to operate upon him for it under chloroform, and cure him immediately."

Arthur leaped from his seat like one demented. "Operate

upon him, cure him!" he cried hastily.

do you mean, Harry?"

"What on earth

"My dear boy, don't be so excited," said Freeling. "This suspense and sleeplessness have been too much for you. This is antivivisection carried ad absurdum. You don't mean to say you object to operations upon a monkey for his own benefit, do you? If I don't cut a nerve, tetanus will finally set in, and he'll die of it in great agony. Drink off your brandy, and you'll feel better after it."

"But, Harry, what's the matter with the monkey? For heaven's sake, tell me!"

Harry Freeling looked at his friend for the first time a little suspiciously. Could Warminster be right after all, and could Arthur really be going mad? It was so ridiculous of him to get into such a state of flurry about the ailments of a tame monkey, and at such a moment, too! Well," he answered slowly, "the monkey has got facial distortions due to a slight local paralysis of the inhibitory nerves supplied to the buccal and pharyngeal muscles, with a tendency to end in tetanus. If I cut a small ganglion behind the ear, and exhibit santonin, the muscles. will be relaxed; and though they won't act so freely as before, they won't jerk and grimace any longer."

"Does it ever occur in human beings? "Arthur asked cagerly.

"Occur in human beings? Bless my soul, yes! I've seen dozens of cases. Why, goodness gracious, Arthur, it's positively occurring in your own face at this very moment!"

"I know it is," Arthur answered in an agony of suspense. "Do you think this twitching of mine is due to a local paralysis of the inhibitories, such as you speak of?"

"Excuse my laughing, my dear fellow; you really do look so absurdly comical. No, I don't think anything about it. I know it is."

“Then you believe Warminster was wrong in taking it for a symptom of incipient insanity?"

It was Freeling's turn now to jump up in surprise. "You don't mean to tell me, Arthur, that that was the sole ground on which that old fool, Warminster, thought you were going crazy?"

"He didn't see it himself," answered Arthur, with a sigh of unspeakable relief. "I only described it to him, and he drew his inference from what I told him. But the real question is this, Harry: Do you feel quite sure that there's nothing more than that the matter with me?" I can cure you

Absolutely certain, my dear fellow.

in half an hour. I've done it dozens of times before, and know the thing as well as you know an ordinary case of scarlet fever."

Arthur sighed again. "And perhaps," he said bitterly, "this terrible mistake may cost dear Hetty her life!"

He drank off the brandy, ate a few mouthfuls of food as best he might, and hastened back to the Aburys'. When he got there he learned from the servant that Hetty was at least no worse; and with that negative comfort he had for the moment to content himself.

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 con

valescent. 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 Académie 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 Académie. Strange to say, the members of the Académie 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 Académie decrees its gold medal for physical discovery to M. Arthur Greatrex, of London, which is a subject of congratulation for us three, and a regular slap in the face for pompous old Linklight."

Hetty seized Freeling's two hands in hers. "You have been our good genius, Dr. Freeling," she said with brimming eyes. "I owe Arthur to you; and Arthur owes me to you; and now we both owe you this. What can we ever do to thank you sufficiently?"

Since those days Hetty and Arthur have long been married, and Dr. Greatrex's famous work (in its enlarged form) has been translated into all the civilized languages of the world, as well as into German; but to this moment, happy as they both are, you can read in their faces the lasting marks of that one terrible anxiety. To many of their friends it seemed afterwards a mere laughing matter; but to those two, who went through it, and especially to Arthur Greatrex, it is a memory too painful to be looked back upon even now without a thrill of terrible recollection.
