"We will first place it in this glass bowl, and pour over it sufficient liquid air to cover it completely. We will let it remain until it is thoroughly cold, say, at least 200° below zero; there—now all we have to do is to heat it and then subject it to a powerful—Great Gee Hosiphat! Five minutes to twelve! I must go—appointment with a lady at twelve. But I say, old fellow, just hold it under the blowpipe and get it hot—just as hot as you can; I will be back soon—ta-ta." His last words came to me faintly through the window—he had already floated out.

I took the queer-colored piece of coal, and began heating it under the blowpipe. It did not burn, as I thought it would, but turned red and then white; gradually it

seemed to grow larger and larger and brighter and brighter until I opened my eyes and found myself in bed with the sun shining full upon me through the open window.

AN INTERESTING GHOST.

[DR. WATSON'S STORY.]

It is with the greatest difficulty, (said Dr. Watson), that I force myself to believe that what I am about to relate to you did not actually happen. It seemed to me that I was as wide-awake as I am at this present moment, and impossible that the strange series of incidents could be due entirely to mental disturbances. I went home and went to bed, after first taking the powder, and I think I went to sleep. How long I slept I do not know, but I was startled at finding myself floating about the room with much the same feeling as one has when floating in water, only it was without effort. My motion seemed to be governed entirely

by my will,—if I glanced at anything in the room I would float towards it. Imagine my astonishment at seeing my body lying in the bed apparently sound asleep; you will admit the sensation was novel, to say the least.

After floating around the room two or three times enjoying the peculiar sensation, I began to wonder what they had been doing at the hospital during my absence. Immediately I found myself in the hospital ward. Dr. Ford and two nurses were standing by a cot at the north end, and glancing at the chart on the table I saw the patient was seriously ill.
