"I have every expectation," said the Chemist, "that this suit and harness will contract in size uniformly with me. If the harness should not, then I shall have to hold the vials in my hand."
On the table, directly under the light, he spread a large silk handkerchief, upon which he placed the ring. He then produced a teaspoon, which he handed to the Doctor.
"Please listen carefully," he said, "for perhaps the whole success of my adventure, and my life itself, may depend upon your actions during the next few minutes. You will realize, of course, that when I am still large enough to be visible to you I shall be so small that my voice may be inaudible. Therefore, I want you to know, now, just what to expect.
"When I am something under a foot high, I shall step upon that handkerchief, where you will see my white suit plainly against its black surface. When I become less than an inch high, I shall run over to the ring and stand beside it. When I have diminished to about a quarter of an inch, I shall climb upon it, and, as I get smaller, will follow its surface until I come to the scratch.
"I want you to watch me very closely. I may miscalculate the time and wait until I am too small to climb upon the ring. Or I may fall off. In either case, you will place that spoon beside me and I will climb into it. You will then do your best to help me get on the ring. Is all this quite clear?"
"Very well, watch me as long as I remain visible. If I have an accident, I shall take the other drug and endeavor to return to you at once. This you must expect at any moment during the next forty-eight hours. Under all circumstances, if I am alive, I shall return at the expiration of that time.
"And, gentlemen, let me caution you most solemnly, do not allow that ring to be touched until that length of time has expired. Can I depend on you?"
"After I have taken the pills," the Chemist continued, "I shall not speak unless it is absolutely necessary. I do not know what my sensations will be, and I want to follow them as closely as possible." He then turned out all the lights in the room with the exception of the center electrolier, that shone down directly on the handkerchief and ring.
The Chemist looked about him. "Good-by, gentlemen," he said, shaking hands all round. "Wish me luck," and without hesitation he placed the four pills in his mouth and washed them down with a swallow of water.
