"No, sir; this man's name is Futashima. There was another Jap in the works, a chap named Itu, a pal of Futashima's, but he's left."
"Ah! I don't know either of them. By the way, usen't there to be a cab-yard just about here?"
"There's a yard up Rankin Street where they keep vans and one or two cabs. That chap Itu works there now. Taken to horseflesh. Drives a van sometimes. Queer start for a Jap."
"Very." Thorndyke thanked the man for his information, and we sauntered on towards Rankin Street. The yard was at this time nearly deserted, being occupied only by an ancient and crazy four-wheeler and a very shabby hansom.
"Curious old houses, these that back on to the yard," said Thorndyke, strolling into the enclosure. "That timber gable, now," pointing to a house, from a window of which a man was watching us suspiciously, "is quite an interesting survival."
"What's your business, mister?" demanded the man in a gruff tone.
"We are just having a look at these quaint old houses," replied Thorndyke, edging towards the back of the hansom, and opening his pocket-book, as though to make a sketch.
"Well, you can see 'em from outside," said the man.
"So we can," said Thorndyke suavely, "but not so well, you know."
At this moment the pocket-book slipped from his hand and fell, scattering a number of loose papers about the ground under the hansom, and our friend at the window laughed joyously.
"No hurry," murmured Thorndyke, as I stooped to help him to gather up the papers—which he did in the most surprisingly slow and clumsy manner. "It is fortunate that the ground is dry." He stood up with the rescued papers in his hand, and, having scribbled down a brief note, slipped the book in his pocket.
"Now you'd better mizzle," observed the man at the window.
"Thank you," replied Thorndyke, "I think we had;" and, with a pleasant nod at the custodian, he proceeded to adopt the hospitable suggestion.

"Mr. Marchmont has been here, sir, with Inspector Badger and another gentleman," said Polton, as we entered our chambers. "They said they would call again about five."
"Then," replied Thorndyke, "as it is now a quarter to five, there is just time for us to have a wash while you get the tea ready. The particles that float in the atmosphere of Limehouse are not all mother-of-pearl."
Our visitors arrived punctually, the third gentleman being, as we had supposed, Mr. Solomon Löwe. Inspector Badger I had not seen before, and he now impressed me as showing a tendency to invert the significance of his own name by endeavouring to "draw" Thorndyke; in which, however, he was not brilliantly successful.
"I hope you are not going to disappoint Mr. Löwe, sir," he commenced facetiously. "You have had a good look at that hat—we saw your marks on it—and he expects that you will be able to point us out the man, name and address all complete." He grinned patronizingly at our unfortunate client, who was looking even more haggard and worn than he had been on the previous morning.
"Have you—have you made any—discovery?" Mr Löwe asked with pathetic eagerness.
"We examined the hat very carefully, and I think we have established a few facts of some interest."
"Did your examination of the hat furnish any information as to the nature of the stolen property, sir?" inquired the humorous inspector.
Thorndyke turned to the officer with a face as expressionless as a wooden mask.
"We thought it possible," said he, "that it might consist of works of Japanese art, such as netsukes, paintings, and such like."
Mr. Löwe uttered an exclamation of delighted astonishment, and the facetiousness faded rather suddenly from the inspector's countenance.
"I don't know how you can have found out," said he. "We have only known it half an hour ourselves, and the wire came direct from Florence to Scotland Yard."
"Perhaps you can describe the thief to us," said Mr. Löwe, in the same eager tone.
"I dare say the inspector can do that," replied Thorndyke.
"Yes, I think so," replied the officer. "He is a short strong man, with a dark complexion and hair turning grey. He has a very round head, and he is probably a workman engaged at some whiting or cement works. That is all we know; if you can tell us any more, sir, we shall be very glad to hear it."
"I can only offer a few suggestions," said Thorndyke, "but perhaps you may find them useful. For instance, at 13, Birket Street, Limehouse, there is living a Japanese gentleman named Futashima, who works at Badcomb and Martin's mother-of-pearl factory. I think that if you were to call on him, and let him try on the hat that you have, it would probably fit him."
The inspector scribbled ravenously in his notebook, and Mr. Marchmont—an old admirer of Thorndyke's—leaned back in his chair, chuckling softly and rubbing his hands.
"Then," continued my colleague, "there is in Rankin Street, Limehouse, a cab-yard, where another Japanese gentleman named Itu is employed. You might find out where Itu was the night before last; and if you should chance to see a hansom cab there—number 22,481—have a good look at it. In the frame of the number-plate you will find six small holes. Those holes may have held brads, and the brads may have held a false number card. At any rate, you might ascertain where that cab was at 11.30 the night before last. That is all I have to suggest."
Mr. Löwe leaped from his chair. "Let us go—now—at once—there is no time to be lost. A thousand thanks to you, doctor—a thousand million thanks. Come!"
He seized the inspector by the arm and forcibly dragged him towards the door, and a few moments later we heard the footsteps of our visitors clattering down the stairs.
"It was not worth while to enter into explanations with them," said Thorndyke, as the footsteps died away—"nor perhaps with you?"
"On the contrary," I replied, "I am waiting to be fully enlightened."
"Well, then, my inferences in this case were perfectly simple ones, drawn from well-known anthropological facts. The human race, as you know, is roughly divided into three groups—the black, the white, and the yellow races. But apart from the variable quality of colour, these races have certain fixed characteristics associated especially with the shape of the skull, of the eye-sockets, and the hair.
"Thus in the black races the skull is long and narrow, the eye-sockets are long and narrow, and the hair is flat and ribbon-like, and usually coiled up like a watch-spring. In the white races the skull is oval, the eye-sockets are oval, and the hair is slightly flattened or oval in section, and tends to be wavy; while in the yellow or Mongol races, the skull is short and round, the eye-sockets are short and round, and the hair is straight and circular in section. So that we have, in the black races, long skull, long orbits, flat hair; in the white races, oval skull, oval orbits, oval hair; and in the yellow races, round skull, round orbits, round hair.
"Now, in this case we had to deal with a very short round skull. But you cannot argue from races to individuals; there are many short-skulled Englishmen. But when I found, associated with that skull, hairs which were circular in section, it became practically certain that the individual was a Mongol of some kind. The mother-of-pearl dust and the granules of rice starch from the inside of the hat favoured this view, for the pearl-shell industry is specially connected with China and Japan, while starch granules from the hat of an Englishman would probably be wheat starch.
"Then as to the hair: it was, as I mentioned to you, circular in section, and of very large diameter. Now, I have examined many thousands of hairs, and the thickest that I have ever seen came from the heads of Japanese; but the hairs from this hat were as thick as any of them. But the hypothesis that the burglar was a Japanese received confirmation in various ways. Thus, he was short, though strong and active, and the Japanese are the shortest of the Mongol races, and very strong and active.
"Then his remarkable skill in handling the powerful caretaker—a
