As the weeks passed, I observed with regret that my new friend was indeed slowly but unmistakably losing ground physically, as Mrs. Herrero had suggested. The livid aspect of his countenance was intensified, his voice became more hollow and indistinct, his muscular motions were less perfectly coördinated, and his mind and will displayed less resilience and initiative.

Of this sad change he seemed by no means unaware, and little by little his expression and conversation both took on a gruesome irony which restored in me something of the subtle repulsion I had originally felt. He developed strange caprices, acquiring a fondness for exotic spices and Egyptian incense till his room smelled like the vault of a sepulchred Pharaoh in the Valley of Kings. At the same time his demands for cold air increased, and with my aid he amplified the ammonia piping of his room and modified the pumps and feed of his refrigerating machine till he could keep the temperature as low as 34° or 40° and finally even 28°; the bathroom and laboratory, of course, being less chilled, in order that water might not freeze, and that chemical processes might not be impeded.

The tenant adjoining him complained of the icy air from around the connecting door, so I helped him fit heavy hangings to obviate the difficulty. A kind of growing horror, of outré and morbid cast, seemed to possess him. He talked of death incessantly, but laughed hollowly when such things as burial or funeral arrangements were gently suggested.

All in all, he became a disconcerting and even gruesome companion; yet in my gratitude for his healing I could not well abandon him to the strangers around him, and was careful to dust his room and attend to his needs each day, muffled in a heavy ulster which I bought especially for the purpose. I likewise did much of his shopping, and gasped in bafflement at some of the chemicals he ordered from druggists and laboratory supply houses. An increasing and unexplained atmosphere of panic seemed to rise around his apartment.

The whole house, as I have said, had a musty odour; but the smell in his room was worse—and in spite of all the spices and incense, and the pungent chemicals of the now incessant baths which he insisted on taking unaided. I perceived that it must be connected with his ailment, and shuddered when I reflected on what that ailment might be. Mrs.

Herrero crossed herself when she looked at him, and gave him up unreservedly to me; not even letting her son Esteban continue to run errands for him. When I suggested other physicians, the sufferer would fly into as much of a rage as he seemed to dare to entertain. He evidently feared the physical effect of violent emotion, yet his will and driving force waxed rather than waned, and he refused to be confined to his bed.

The lassitude of his earlier ill days gave place to a return of his fiery purpose, so that he seemed about to hurl defiance at the death-daemon even as that ancient enemy seized him. The pretence of eating, always curiously like a formality with him, he virtually abandoned; and mental power alone appeared to keep him from total collapse.
