unquestionably Caucasian.
This was encouraging, despite the fact that most of the facts obtained were already known to Dr. Thane. If the deceased was, as the scientist had expected and had assumed, a Latin-American, then the blood specialist had been right; there would be traces of negro and Indian blood in the specimens submitted. And if, argued the scientist, the report on the pigmentation of the skin confirmed this, then he would have been proved correct, for the puzzling hair neither confirmed nor contradicted the other report. But when at last the report on the skin reached Dr. Thane, he was as far from making headway as ever. The skin, so the report stated, showed no traces of either African or Indian pigmentation, but was distinctly Caucasian, with some doubtful characteristics pointing toward a slight Mongolian strain.
"Hmm," mused Dr. Thane, "All this time wasted on these investigations and no definite results. I wonder what the fellow actually was. Let me see. To sum up: Assuming all the reports correct, we haveâCaucasian, predominant; Mongolian, fairly certain, as reported both in skin and blood; possibility of African and Indian. Hump! By Jove!" suddenly alert. "That would be possible, yes, highly probable, for a Latin-American. But the hair! Freak, abnormal, an aberrant form of growth probably. Yes, Iâ"
Dr. Thane's thoughts were rudely interrupted by the jingle of his telephone bell.
"That you, Doctor?" came in familiar tones. "Yes, this is Haley speaking. Can you meet me at the morgue in twenty minutes? Have a man here who feels positive he can identify the body of the ash-can murder. What's that? Oh, yes. Just arrived in the city. Thought you'd be interested."
CHAPTER VÂ
Positive Identification
Dr. Thane reached the morgue a few minutes before Captain Haley, who was accompanied by a rather good-looking man dressed in neat but inexpensive clothes. His face was deeply sunburned, and something in the expression of his gray eyes and his manner told the scientist that he was a member of the seafaring profession.
The detective introduced him as Captain Scarsdale, adding the information that he had arrived on his ship the preceding evening. Having seen the pictures of the murdered man in some old papers, and being sure that he had recognized the victim of the tragedy, he had lost no time in coming to identify the body.
"If you have no objections, Captain Scarsdale," said Dr. Thane, "I would like to ask you a few questions before you view the body. As, no doubt, Mr. Haley has told you, we have had many identifications, all of which have so far proved incorrect. Very often, I have found, a man's or a woman's mental processes play them false. Having once come to the conclusion that they know the deceased, they always see a resemblance in the cadaver's altered countenance and features which, in their rather excited psychological state, appears most striking and unmistakable. As a result, they feel positive that the body is that of the individual whom they have already, quite unconsciously, decided it to be!"
The mariner laughed. "Guess you won't find me much excited or making any mistake," he declared confidently. "But I see your point. Sort of autosuggestion, as the books call it. Folks make up their minds it's Tom, Dick or Harry, and jolly 'emselves into believing it is, eh?"
"Precisely," agreed Dr. Thane. "But if you will answer a few queries before viewing the murdered man, it may make identity more certain. Would you mind giving us a detailed description of the man whose body you surmise was found?"
"Not a bit," declared the captain. "Chap about five foot six; stocky build, black hair a bit gray on the sides; eyes grayish-brownâguess you'd call 'em hazel. Small black mustache; good teeth, and about forty-six years old. How does that fit?"
"Excellently, excellently," cried the scientist. "But not exactly. You say this man wore a small mustache. The body has a clean-shaven face and there
