On the 24th of February, 1810, the look-out at Notre-Dame de la Garde signalled the three-master, the Pharaon from Smyrna, Trieste, and Naples.

As usual, a pilot put off immediately, and rounding the Chateau d'If, got on board the vessel between Cape Morgion and Rion island.

Immediately, and according to custom, the ramparts of Fort Saint-Jean were covered with spectators; it is always an event at Marseilles for a ship to come into port, especially when this ship, like the Pharaon, has been built, rigged, and laden at the old Phocee docks, and belongs to an owner of the city.

The ship drew on and had safely passed the strait, which some volcanic shock has made between the Calasareigne and Jaros islands; had doubled Pomegue, and approached the harbor under topsails, jib, and spanker, but so slowly and sedately that the idlers, with that instinct which is the forerunner of evil, asked one another what misfortune could have happened on board. However, those experienced in navigation saw plainly that if any accident had occurred, it was not to the vessel herself, for she bore down with all the evidence of being skilfully handled, the anchor a-cockbill, the jib-boom guys already eased off, and standing by the side of the pilot, who was steering the Pharaon towards the narrow entrance of the inner port, was a a young man, who, with activity and vigilant eye, watched every motion of the ship, and repeated each direction of the pilot.

The vague disquietude which prevailed among the spectators had so much affected one of the crowd that he did not await the arrival of the vessel in harbor, but jumping into a small skiff, desired to be pulled alongside the Pharaon, which he reached as she rounded into La Reserve basin.

When the young man on board saw this person approach, he left his station by the pilot, and, hat in hand, leaned over the ship's bulwarks.

He was a fine, tall, slim young fellow of eighteen or twenty, with black eyes, and hair as dark as a raven's wing; and his whole appearance bespoke that calmness and resolution peculiar to men accustomed from their cradle to contend with danger.

"Ah, is it you, Dantes?" cried the man in the skiff. "What's the matter? and why have you such an air of sadness aboard?"

"A great misfortune, M. Morrel," replied the young man, -- "a great misfortune, for me especially! Off Civita Vecchia we lost our brave Captain Leclere."

"And the cargo?" inquired the owner, eagerly.

"Is all safe, M. Morrel; and I think you will be satisfied on that head. But poor Captain Leclere -- "

"What happened to him?" asked the owner, with an air of considerable resignation. "What happened to the worthy captain?"

"He died."

"Fell into the sea?"

"No, sir, he died of brain-fever in dreadful agony." Then turning to the crew, he said, "Bear a hand there, to take in sail!"

All hands obeyed, and at once the eight or ten seamen who composed the crew, sprang to their respective stations at the spanker brails and outhaul, topsail sheets and halyards, the jib downhaul, and the topsail clewlines and buntlines. The young sailor gave a look to see that his orders were promptly and accurately obeyed, and then turned again to the owner.

“What happened was this. Two days ago I received the letter which I now read to you. Neither address nor date is attached to it.

“A Russian nobleman who is now resident in England [it

runs], would be glad to avail himself of the professional

assistance of Dr. Percy Trevelyan. He has been for some

years a victim to cataleptic attacks, on which, as is well

known, Dr. Trevelyan is an authority. He proposes to call at

about a quarter-past six to-morrow evening, if Dr. Trevelyan

will make it convenient to be at home.

“This letter interested me deeply, because the chief difficulty in the study of catalepsy is the rareness of the disease. You may believe, then, that I was in my consulting-room when, at the appointed hour, the page showed in the patient.

“He was an elderly man, thin, demure, and commonplace — by no means the conception one forms of a Russian nobleman. I was much more struck by the appearance of his companion. This was a tall young man, surprisingly handsome, with a dark, fierce face, and the limbs and chest of a Hercules. He had his hand under the other’s arm as they entered, and helped him to a chair with a tenderness which one would hardly have expected from his appearance.

“‘You will excuse my coming in, Doctor,’ said he to me, speaking English with a slight lisp. ‘This is my father, and his health is a matter of the most overwhelming importance to me.’

“I was touched by this filial anxiety. ‘You would, perhaps, care to remain during the consultation?’ said I.

“‘Not for the world,’ he cried with a gesture of horror. ‘It is more painful to me than I can express. If I were to see my father in one of these dreadful seizures I am convinced that I should never survive it. My own nervous system is an exceptionally sensitive one. With your permission, I will remain in the waiting-room while you go into my father’s case.’

“To this, of course, I assented, and the young man withdrew. The patient and I then plunged into a discussion of his case, of which I took exhaustive notes. He was not remarkable for intelligence, and his answers were frequently obscure, which I attributed to his limited acquaintance with our language. Suddenly, however, as I sat writing, he ceased to give any answer at all to my inquiries, and on my turning towards him I was shocked to see that he was sitting bolt upright in his chair, staring at me with a perfectly blank and rigid face. He was again in the grip of his mysterious malady.

“My first feeling, as I have just said, was one of pity and horror. My second, I fear, was rather one of professional satisfaction. I made notes of my patient’s pulse and temperature, tested the rigidity of his muscles, and examined his reflexes. There was nothing markedly abnormal in any of these conditions, which harmonized with my former experiences. I had obtained good results in such cases by the inhalation of nitrite of amyl, and the present seemed an admirable opportunity of testing its virtues. The bottle was downstairs in my laboratory, so, leaving my patient seated in his chair, I ran down to get it. There was some little delay in finding it — five minutes, let us say — and then I returned. Imagine my amazement to find the room empty and the patient gone.
