We did not touch at Aden, and I was glad of it. The few attractions of the place, the diving boys and the like, may be a relief in ordinary sea voyages, but I was too much absorbed in my experiment on Brande to bear with patience any delay which served to postpone the crisis of my scheme. I had treated him well, so far as his bodily health went, but I deliberately continued to tamper with his brain, so that any return of his telepathic power was thus prevented. Indeed, Brande himself was not anxious for such return. The power was always exercised at an extreme nervous strain, and it was now, he said, unnecessary to his purpose. In consequence of this determination, I modified the already minute doses of the drug I was giving him. This soon told with advantage on his health. His physical improvement partly restored his confidence in me, so that he followed my instructions faithfully. He evidently recognised that he was in my power; that if I did not choose to restore him fully no other man could. Of the ship's officers, Anderson, who was in command, and Percival, the doctor, were men of some individuality. The captain was a good sailor and an excellent man of business. In the first capacity, he was firm, exacting, and scrupulously conscientious. In the second, his conscience was more elastic when he saw his way clear to his own advantage. He had certain rigid rules of conduct which he prided himself on observing to the letter, without for a moment suspecting that their _raison d'etre_ lay in his own interests. His commercial morality only required him to keep within the law. His final contract with myself was, I admit, faithfully carried out, but the terms of it would not have discredited the most predatory business man in London town. Percival was the opposite pole of such a character. He was a clever man, who might have risen in his profession but for his easy-going indolence. I spent many an hour in his cabin. He was a sportsman and a skilled _raconteur_. His anecdotes helped to while the weary time away. He exaggerated persistently, but this did not disturb me. Besides, if in his narratives he lengthened out the hunt a dozen miles and increased the weight of the fish to an impossible figure, made the brace a dozen and the ten-ton boat a man-of-war, it was not because he was deliberately untruthful. He looked back on his feats through the telescope of a strongly magnifying memory. It was more agreeable to me to hear him boast his prowess than have him inquire after the health and treatment of my patient Brande. On this matter he was naturally very curious, and I very reticent.
