Passing into the laboratory first, I noticed that a trestle-work similar to that in the court-yard stood in the centre of the floor, and that it was surmounted by a shallow pan of zinc, fitted at one end with a waste-pipe, like that of a bath-tub, leading to the gutter of the court. I was still further surprised to note, when I passed on into the studio, that the centre of that chamber also contained what might be termed a supplement to the trestle-work, in that the furniture had been moved to one side to make room for an improvised table on which rested an ordinary mattress. In addition to this a bureau-bed had been unfolded and set in readiness at one of the walls, while a blazing fire burned in the grate, although the day was anything but cold. Before I had time to speculate upon the meaning of all these mysterious preparations, I heard Burnham calling, so throwing my coat on a settee I hastened to join him. I found him engaged in firing up a small portable steam-engine that stood in one corner of the yard, and in affixing to the exhaust-pipe of the cylinder another pipe, several feet in length, with a movable arm, evidently for the purpose of ejecting steam in any desired direction. “Now,” he said, as he completed the connection, “while the boiler is getting up steam, you and I must get to work and uncover our package. I expected Dr. Dunne here before this, but doctors, you know, are always entitled to latitude in non-professional matters.” So saying, he took a knife and began to cut away the ropes from the package, I following his example. Then we removed layer after layer of sacking, the air growing, I thought, all the time sensibly colder, till upon removing the last of the sack-cloth--we could not, of course, remove the wrapping on which the weight rested, but merely contented ourselves with ripping the top open and letting it fall on either side--what was my surprise to see before me an immense oblong block of blue, pellucid ice. But who shall express my feelings when, a moment after, I discerned _imbedded in the heart of the transparent crystal the form of a man_.
