Jails would be more numerous than churches, were natural criminals surely shadowed forth in visible signs such as long, tapering fingers; rodent eyes, or those bead-like, shifty, countersunk and narrowly spaced; bull neck, connected with a vertically-lined back head; laterally-extended side-jaw bones; protruding fore jaw; the ape's forehead, marked by the ape's fuzzy hairline, the same fuzzy hair extending inward from under the outer edges of the eye sockets; eagle's beak, or more commonly, the tangential, flattened nose of the gorilla, with arms like his, unusually long and big-boned as compared with the rest of the frame; thin lips, emphasizing a cruelly-set mouth, or thick lip above a ponderous jaw; and ears in all sizes, conformation, setting and contour, opposed to the perfect model. It is true that the predal felon frequently features several of such as the signs indicated. It is also true that millions of honest freemen feature the same signs, and do no worse than dissemble, as more or less do all humans. And it is further true that, in so far as emphasis on such symbols is concerned, the bulk of lawbreakers would pass unnoticed in a promiscuous crowd. Still, close parallels prevail as between members of classes of the anti-social. They ply the same tools, speak the same language, are bound by and large by the same laws of clan, foregather in the same caves of earth, affect the same mannerisms and mental attitude, and spend ill-gotten gain for intrinsically the same things, if over different counters; but they do not yield of themselves in the same measure to the powers of darkness. If they did, the bulk of them would be capital criminals, instead of offenders against property. Usually the pack are of one mind as to the method of procedure, else they wouldn't "pal" it as one. Type then matches type as closely as members of criminal types match; yet no two will be actuated by absolutely the same motives, and no two will have come by motives to act in absolutely the same way. The demarcation may call for the most careful of research; but it will be there, and it will demarcate, if only by shading so slight as to escape other than the truly expert examiner. Glaring cross-matches of type evolve not infrequently, as for example: of two on the same job, the one would ride rough-shod and quickly over human life to what he seeks. The other balks, then and there, at ruthless spilling of blood, and will "queer the deal" rather than be party to a killing.
