Another glance, however, showed that it was merely the impression of one, the actual bones had long since disappeared. The ribs, the skull, and limbs were drawn on the black ground in white lines as if it had been done with a broad piece of chalk. Close by he found three or four more, intertangled and superimposed as if the unhappy beings had fallen partly across each other, and in that position had mouldered away leaving nothing but their outline. From among a variety of objects that were scattered about Felix picked up something that shone; it was a diamond bracelet of one large stone, and a small square of blue china tile with a curious heraldic animal drawn on it. Evidently these had belonged to one or other of the party who had perished. Though startled at the first sight, it was curious that Felix felt so little horror; the idea did not occur to him that he was in danger as these had been. Inhaling the gaseous emanations from the soil and contained in the yellow vapour, he had become narcotized, and moved as if under the influence of opium, while wide awake, and capable of rational conduct. His senses were deadened, and did not carry the usual vivid impression to the mind; he saw things as if they were afar off. Accidentally looking back, he found that his footmarks, as far as he could see, shone with a phosphoric light like that of "touchwood" in the dark. Near at hand they did not shine; the appearance did not come till some few minutes had elapsed. His track was visible behind till the vapour hid it. As the evening drew on the vapour became more luminous, and somewhat resembled an aurora. Still anxious for water, he proceeded as straight ahead as he could, and shortly became conscious of an indefinite cloud which kept pace with him on either side. When he turned to look at either of the clouds, the one looked at disappeared. It was not condensed enough to be visible to direct vision, yet he was aware of it from the corner of his eye. Shapeless and threatening, the gloomy thickness of the air floated beside him like the vague monster of a dream. Sometimes he fancied that he saw an arm or a limb among the folds of the cloud, or an approach to a face; the instant he looked it vanished. Marching at each hand these vapours bore him horrible company. His brain became unsteady, and flickering things moved about him; yet, though alarmed, he was not afraid; his senses were not acute enough for fear. The heat increased; his hands were intolerably hot as if he had been in a fever, he panted; but did not perspire. A dry heat like an oven burned his blood in his veins. His head felt enlarged, and his eyes seemed alight; he could see these two globes of phosphoric light under his brows. They seemed to stand out so that he could see them. He thought his path straight, it was really curved; nor did he know that he staggered as he walked.
