at the great fireclay drum, Marchmont and Humperdinck began to yawn in the most portentous manner. I rather wondered that they did not go, for the investigation was no business of theirs, and there was little entertainment in gazing at the outside of the furnace or watching Polton and the Superintendent gather up the masses of slag from the plate and drop them into the casket. But I supposed that they, like myself, were consoling themselves for the tedium of the chemist's manipulations by the prospect of satisfying their curiosity as to the final result of the experiment.

      When at length, the last charge was ready, Woodfield withdrew the white-hot crucible from the furnace and stood it on the iron plate. But this time he did not pour out the contents. Instead, he tilted the iron mould, and, picking out the conical masses of slag that it contained, one by one, lowered them with his tongs into the hot crucible. Then, having thrown in a little fresh flux, he returned the crucible to the furnace. "Why didn't he pour out the melted stuff this time?" Marchmont asked.

      "Because," Thorndyke replied, "I want, for certain reasons, to have the total result of the analysis in a single mass. Each of those little cones of slag contains the result from a sixth part of the ash; the crucible now contains the matter extracted from the whole of the ashes. For my purposes this is more suitable, as you will see in a few minutes—for we shall not have to leave the crucible in the furnace so long this time."

      "I'm glad of that," said Marchmont, "though this has been a most interesting, and I may say, fascinating experience. I am delighted to have had an opportunity of witnessing these most instructive and—er—aw—"

      The rest of the sentence was rendered somewhat obscure by a colossal yawn; but very soon the interest of the proceedings was revived by Woodfield, who approached the furnace with a determined air and removed its cover with somewhat of a flourish. "Now we shall see, Thorndyke," said he, turning off the gas and reaching down into the glowing cavity with his tongs. He lifted out the crucible and, standing it on the iron plate, took out the nails, tapping each on the side of the pot as he withdrew it. "Do you want me to pour it out, or shall I break the pot?" asked Woodfield.

      "That rests with you," replied Thorndyke.

      "Better break the pot, then," said Woodfield.

      This entailed a further spell of expectant waiting, and we all stood round, gazing impatiently at the crucible as it slowly faded from bright red to dull red and from this to its natural dull drab. It was quite a long time before Woodfield considered it cool enough to be broken, indeed I half suspected him of prolonging our suspense with deliberate malice. At length he took up a peculiarly-shaped hammer which Polton had handed to him, and, laying the crucible on its side, struck it sharply near the bottom with the pointed beak; then he turned the pot over and struck a similar blow on the opposite side; upon which the bottom of the crucible broke off cleanly, exposing the mass of dark, glassy slag, and, embedded in it, a bright button of metal. "What metal is that?" Jervis demanded eagerly.

      The professor struck the button smartly with the hammer, whereupon it detached itself from the slag and rolled on to the plate. "Lead," said he. "I don't vouch for its parity, but it is undoubtedly lead."

      Jervis turned to Thorndyke with a puzzled look. "You can't be suggesting," said he, "that this was a case of acute lead poisoning. The circumstances didn't admit of it, and besides, the quantity of lead is impossibly large."

      "I should suppose," interposed Miller, "that the doctor was suggesting a most particularly acute form of lead poisoning, only that it is impossible to imagine that a cremation certificate would be granted in a case where a man had been killed by a pistol shot."

      "I am not so sure of that," said Thorndyke; "though it is not likely that a cremation certificate would be applied for under those circumstances. But I am certainly not suggesting lead poisoning."

      "What do you say is the weight of this button, Thorndyke?" the professor asked.

      "That," replied Thorndyke, "depends on its relation to the total content of lead in the ashes. What percentage do you suppose has been lost in the process of reduction?"

      "Not more than ten per cent. I hope. You may take this button as representing ninety per cent of the total lead; perhaps a little more."

      Thorndyke made a rapid calculation on a scrap of paper. "I suggest," said he, "that the total lead in the ashes was three hundred and eighty-six grains. Deducting a tenth, say thirty-eight and a half grains, we have three hundred and forty-seven and a half grains, which should be the weight of this button."

      Woodfield picked up the button and striding over to the glass case which contained the chemical balance, slid up the front, and, placing the button in one pan, put the weight corresponding to Thorndyke's estimate, in the other. On turning the handle that released the balance, it was seen that the button was appreciably heavier than Thorndyke had stated, and Woodfield adjusted the weights with a small pair of forceps until the index stood in the middle of the graduated arc. "The weight is three hundred and forty-nine and a half grains," said Woodfield. "That means that my assay was rather better than I thought. You were quite right, Thorndyke, as you generally are. I wonder what the object was that weighed three hundred and eighty-six grains. Are you going to tell us?"

      Thorndyke felt in his waistcoat pocket. "It was an object," said he," very similar to this."

      As he spoke, he produced a rather large, dark-coloured bullet, which he handed to Woodfield, who immediately placed it in the pan of the balance and tested its weight. "Just a fraction short of three hundred and eighty-seven grains," said he.

      The Superintendent peered curiously into the balance-case, and, taking the bullet out of the pan, turned it over in his fingers. "That's not a modern bullet," said he. "They don't make 'em that size now, and they don't generally make 'em of pure lead."

      "No," Thorndyke agreed. "They don't. This is an old French bullet; a chassepot of about 1870."

      "A chassepot!" exclaimed Humperdinck, with suddenly-awakened interest. "Yes," said Thorndyke; "and this button,"—he picked it up from the floor of the balance-case as he spoke,—" was once a chassepot bullet, too. This, Father Humperdinck," he added, holding out the little mass of metal towards the Jesuit, "was the bullet which struck your friend, Vitalis Reinhardt, near Saarbrück more than thirty years ago."

      The priest was thunderstruck. For some seconds, he gazed from Thorndyke's face to the button of lead, with his mouth agape and an expression of utter stupefaction. "But," he exclaimed, at length, "it is impossible! How can it be, in the ashes of a stranger!"

      "I take it," said Marchmont, "that Dr. Thorndyke is suggesting that this was the body of Vitalis Reinhardt."

      "Undoubtedly I am," said Thorndyke.

      "It sounds a rather bold supposition," Marchmont observed, a little dubiously. "Isn't it basing a somewhat startling conclusion upon rather slender data? The presence of the lead is a striking fact, but still, taken alone—"

      "But it isn't taken alone," Thorndyke interrupted. "It is the final link in a long chain of evidence. You will hear that evidence later, but, as it happens, I can prove the identity of these remains from facts elicited by the examination that we have just made. Let me put the argument briefly.

      "First, I will draw your attention to these plaster casts, which you have seen me make from the original bones, Take, to begin with, these small fragments. Dr. Jervis will tell you what bones they are."

      He handed the small casts to Jervis, who looked them over—not for the first time—and passed them to me. "I say that they represent two complete fingers and the first, or proximal, joint of a right thumb. What do you say, Jardine?"

      "That is what I had already made them out to be," I replied.

      "Very well," said Thorndyke. "That gives us an important initial fact. These remains contained two complete fingers and the first joint of a thumb. But these remains profess to be those of a man named Septimus Maddock. Now this man is known to have had deformed hands, of the kind described as brachydactylous. In such hands all the fingers are incomplete—they have only two joints instead of the normal three—and the first, or proximal joint of the thumb is absent. Obviously, then,
