THE NEXT DAY I woke up with my head unusually clear. Much to my surprise, I was in my stateroom. No doubt my companions had been put back in their cabin without noticing it any more than I had. Like me, they would have no idea what took place during the night, and to unravel this mystery I could count only on some future happenstance.

I then considered leaving my stateroom. Was I free or still a prisoner? Perfectly free. I opened my door, headed down the gangways, and climbed the central companionway. Hatches that had been closed the day before were now open. I arrived on the platform.

Ned Land and Conseil were there waiting for me. I questioned them. They knew nothing. Lost in a heavy sleep of which they had no memory, they were quite startled to be back in their cabin.

As for the Nautilus, it seemed as tranquil and mysterious as ever. It was cruising on the surface of the waves at a moderate speed. Nothing seemed to have changed on board.

Ned Land observed the sea with his penetrating eyes. It was deserted. The Canadian sighted nothing new on the horizon, neither sail nor shore. A breeze was blowing noisily from the west, and disheveled by the wind, long billows made the submersible roll very noticeably.

After renewing its air, the Nautilus stayed at an average depth of fifteen meters, enabling it to return quickly to the surface of the waves. And, contrary to custom, it executed such a maneuver several times during that day of January 19. The chief officer would then climb onto the platform, and his usual phrase would ring through the ship's interior.

As for Captain Nemo, he didn't appear. Of the other men on board, I saw only my emotionless steward, who served me with his usual mute efficiency.

Near two o'clock I was busy organizing my notes in the lounge, when the captain opened the door and appeared. I bowed to him. He gave me an almost imperceptible bow in return, without saying a word to me. I resumed my work, hoping he might give me some explanation of the previous afternoon's events. He did nothing of the sort. I stared at him. His face looked exhausted; his reddened eyes hadn't been refreshed by sleep; his facial features expressed profound sadness, real chagrin. He walked up and down, sat and stood, picked up a book at random, discarded it immediately, consulted his instruments without taking his customary notes, and seemed unable to rest easy for an instant.

Finally he came over to me and said:

"Are you a physician, Professor Aronnax?"

This inquiry was so unexpected that I stared at him a good while without replying.

"Are you a physician?" he repeated. "Several of your scientific colleagues took their degrees in medicine, such as Gratiolet, Moquin-Tandon, and others."

"That's right," I said, "I am a doctor, I used to be on call at the hospitals. I was in practice for several years before joining the museum."

"Excellent, sir."

My reply obviously pleased Captain Nemo. But not knowing what he was driving at, I waited for further questions, ready to reply as circumstances dictated.

"Professor Aronnax," the captain said to me, "would you consent to give your medical attentions to one of my men?"

"Someone is sick?"

"Yes."

"I'm ready to go with you."

"Come."

I admit that my heart was pounding. Lord knows why, but I saw a definite connection between this sick crewman and yesterday's happenings, and the mystery of those events concerned me at least as much as the man's sickness.

Captain Nemo led me to the Nautilus's stern and invited me into a cabin located next to the sailors' quarters.

On a bed there lay a man some forty years old, with strongly molded features, the very image of an Anglo-Saxon.

I bent over him. Not only was he sick, he was wounded. Swathed in blood-soaked linen, his head was resting on a folded pillow. I undid the linen bandages, while the wounded man gazed with great staring eyes and let me proceed without making a single complaint.

It was a horrible wound. The cranium had been smashed open by some blunt instrument, leaving the naked brains exposed, and the cerebral matter had suffered deep abrasions. Blood clots had formed in this dissolving mass, taking on the color of wine dregs. Both contusion and concussion of the brain had occurred. The sick man's breathing was labored, and muscle spasms quivered in his face. Cerebral inflammation was complete and had brought on a paralysis of movement and sensation.

I took the wounded man's pulse. It was intermittent. The body's extremities were already growing cold, and I saw that death was approaching without any possibility of my holding it in check. After dressing the poor man's wound, I redid the linen bandages around his head, and I turned to Captain Nemo.

"How did he get this wound?" I asked him.

"That's not important," the captain replied evasively. "The Nautilus suffered a collision that cracked one of the engine levers, and it struck this man. My chief officer was standing beside him. This man leaped forward to intercept the blow. A brother lays down his life for his brother, a friend for his friend, what could be simpler? That's the law for everyone on board the Nautilus. But what's your diagnosis of his condition?"

I hesitated to speak my mind.

"You may talk freely," the captain told me. "This man doesn't understand French."

I took a last look at the wounded man, then I replied:

"This man will be dead in two hours."

"Nothing can save him?"

"Nothing."

Captain Nemo clenched his fists, and tears slid from his eyes, which I had thought incapable of weeping.

For a few moments more I observed the dying man, whose life was ebbing little by little. He grew still more pale under the electric light that bathed his deathbed. I looked at his intelligent head, furrowed with premature wrinkles that misfortune, perhaps misery, had etched long before. I was hoping to detect the secret of his life in the last words that might escape from his lips!

"You may go, Professor Aronnax," Captain Nemo told me.

I left the captain in the dying man's cabin and I repaired to my stateroom, very moved by this scene. All day long I was aquiver with gruesome forebodings. That night I slept poorly, and between my fitful dreams, I thought I heard a distant moaning, like a funeral dirge. Was it a prayer for the dead, murmured in that language I couldn't understand?

The next morning I climbed on deck. Captain Nemo was already there. As soon as he saw me, he came over.

"Professor," he said to me, "would it be convenient for you to make an underwater excursion today?"

"With my companions?" I asked.

"If they're agreeable."

"We're yours to command, captain."

"Then kindly put on your diving suits."

As for the dead or dying man, he hadn't come into the picture. I rejoined Ned Land and Conseil. I informed them of Captain Nemo's proposition. Conseil was eager to accept, and this time the Canadian proved perfectly amenable to going with us.

It was eight o'clock in the morning. By 8:30 we were suited up for this new stroll and equipped with our two devices for lighting and breathing. The double door opened, and accompanied by Captain Nemo with a dozen crewmen following, we set foot on the firm seafloor where the Nautilus was resting, ten meters down.

A gentle slope gravitated to an uneven bottom whose depth was about fifteen fathoms. This bottom was completely different from the one I had visited during my first excursion under the waters of the Pacific Ocean. Here I saw no fine-grained sand, no underwater prairies, not one open-sea forest. I immediately recognized the wondrous region in which Captain Nemo did the honors that day. It was the coral realm.

In the zoophyte branch, class Alcyonaria, one finds the order Gorgonaria, which contains three groups: sea fans, isidian polyps, and coral polyps. It's in this last that precious coral belongs, an unusual substance that, at different times, has been classified in the mineral, vegetable, and animal kingdoms. Medicine to the ancients, jewelry to the moderns, it wasn't decisively placed in the animal kingdom until 1694, by Peysonnel of Marseilles.
