Again, suppose we find at the beginning of our explanation somany successive points of actual disagreement, how many of thosedivergences constitute a sure and certain refutation or disproof ofidentity? If, for example, we discover four successive disagreementsof pattern need we go any further in our researches ? Are goose andgander not to be served with the same sauce ? Is the defence to havea different measure meted out to it from that given to the prosecution?If again, we find the first four elements examined to prove infalliblythat the source of the two prints is one and the same, and the. Thumb-print of Alfred Stratton (enlarged).Fig. 25. Deptford Mask Murders. 77 defence thereafter has the audacity to go on and find that the fifthand sixth elements in succession are quite discrepant, what is to beour final deduction in the case? Taking the matter up in a severely practical way let us now inimagination divide the two imprints vertically in the middle. Thensupposing the patterns to be composed of flexible twigs which canbe straightened out into a kind of runic alphabet, let us arrange themthus in serial order. Fig. 26. Analytic diagram of an important pattern. Those to the right represent diagrammatically the lineations at theright upper side of the thumb-print, counting towards the bottom ofthe figure. Compare these straightened lines with the curved line-ations of the patterns and dismissing all thought of the allegedincongruousness of the curves from the problem, do we then find asuccessive coincidence of
