XV1 DESCRIPTION OF THE PLATES

PAGE

VII.-Fig. 11. Standard, patterns of Arches, together with some transitional forms, all with their names below 7 5

Fig. 12. As above, with respect to Loops 75

VIII.-Fig. 13. As above, with respect to Whorls . 75

Fig. 14. Cores to Loops, which may consist either of single lines,

here called rods, or of a recurved line or staple, while the ridges that immediately envelops them is called an envelope . 76

Fig. 15. Cores to Whorls 77

IX.-Fig. 15. Transitional patterns, enlarged three times, between Arches and either Loops or Whorls .

X.-Fig. 16. Transitional patterns, as above, but between Loops

and Whorls. 79

XI.-Fig. 17. Diagram showing the nine genera formed by the corresponding combinations of the two letters by which they are expressed, each being i, j, or o as the case may be. The first two diagrams are Arches, and not strictly patterns at all, but may with some justice be symbolised by jj . .

Fig. 18. Ambiguities in minutiae, showing that certain details in them are not to be trusted, while others are . 92

XIL-Fig. 19. The illustrations to Purkenje's Commentatio. They are photo-lithographed from the original, which is not clearly printed .

XIII. -Fig. 20. Enlarged impressions of the same two fingers of V. H. Hd., first when a child of 21, and subsequently when a boy of 15 years of age. The lower pair are interesting from containing the unique case of failure of exact coincidence yet observed. It is marked A. The numerals indicate the correspondences . .

XIV.-Fig. 21, Contains portions on an enlarged scale of eight couplets of finger prints, the first print in each couplet having been taken many years before the second, as shown by the attached dates. The points of correspondence in each couplet are indicated by similar numerals

XV.-Fig. 22. The fore-finger of Sir W. J. Herschel as printed on

two occasions, many years apart (enlarged scale). The numerals are here inserted on a plan that has the merit of clearness, but some of the lineations are thereby sacrificed . 95

Fig. 23. Shows the periods of life over which the evidence of identity extends in Figs 20-22. [By an oversight, not perceived until too late

for remedy, the bottom line begins at set. 62 instead of 67] . 97
