I do not think my mind was occupied in any way. About the only occasions on which, to my knowledge, my mind is actually passive or inert is when crossing the Channel in The Foam from Dover to Calais, when I am always, in every weather, abjectly seasick—and thoughtless. But as I now lay on my bed, uncomfortable, squeamish, without knowing why—I was in the same inactive mental condition. But not for long.

I saw something that startled me.

First, it appeared to me as if the lappet of my overcoat pocket were in movement, being raised. I did not pay much attention to this, as I supposed that the garment was sliding down on to the seat of the sofa, from the back, and that this displacement of gravity caused the movement I observed. But this I soon saw was not the case. That which moved the lappet was something in the pocket that was struggling to get out. I could see now that it was working its way up the inside, and that when it reached the opening it lost balance and fell down again. I could make this out by the projections and indentations in the cloth; these moved as the creature, or whatever it was, worked its way up the lining.

"A mouse," I said, and forgot my seediness; I was interested. "The little rascal! However did he contrive to seat himself in my pocket? and I have worn that overcoat all the morning!" But no—it was not a mouse. I saw something white poke its way out from under the lappet; and in another moment an object was revealed that, though revealed, I could not understand, nor could I distinguish what it was.

Now roused by curiosity, I raised myself on my elbow. In doing this I made some noise, the bed creaked. Instantly the something dropped on the floor, lay outstretched for a moment, to recover itself, and then began, with the motions of a maggot, to run along the floor.

There is a caterpillar called "The Measurer," because, when it advances, it draws its tail up to where its head is and then throws forward its full length, and again draws up its extremity, forming at each time a loop; and with each step measuring its total length. The object I now saw on the floor was advancing precisely like the measuring caterpillar. It had the colour of a cheese-maggot, and in length was about three and a half inches. It was not, however, like a caterpillar, which is flexible throughout its entire length, but this was, as it seemed to me, jointed in two places, one joint being more conspicuous than the other. For some moments I was so completely paralysed by astonishment that I remained motionless, looking at the thing as it crawled along the carpet—a dull green carpet with darker green, almost black, flowers in it.

It had, as it seemed to me, a glossy head, distinctly marked; but, as the light was not brilliant, I could not make out very clearly, and, moreover, the rapid movements prevented close scrutiny.

Presently, with a shock still more startling than that produced by its apparition at the opening of the pocket of my great-coat, I became convinced that what I saw was a finger, a human forefinger, and that the glossy head was no other than the nail.

The finger did not seem to have been amputated. There was no sign of blood or laceration where the knuckle should be, but the extremity of the finger, or root rather, faded away to indistinctness, and I was unable to make out the root of the finger.

I could see no hand, no body behind this finger, nothing whatever except a finger that had little token of warm life in it, no coloration as though blood circulated in it; and this finger was in active motion creeping along the carpet towards a wardrobe that stood against the wall by the fireplace.
